Second of two videos for my MatE115 Crystallography Project. This one covers Martensite and should be watched after the other one since I refer back to it quite a few times. As mentioned before, I was hoping to be able to do animations, especially for the rotations, but this didn't work out. Unfortunately, showing pictures of the rotations just results in several identical pics (as you can imagine), so I had to gloss over that a bit. Still, I think the models I made help with the visualization of the rotations, so it's not a total loss. Lastly, I want to emphasize again that the amount of information I could include was limited. The written report should make up for much of this, so assume any glaring omissions are covered there. P.S. Just noticed that after uploading to YouTube, some of the text is kind of hard to read. Original video files are available upon request.

Ni-Ti Shape Memory Alloys (SMA) alloys have been attracting attention due to a number of desirable properties (shape memory effect,...) The basis of the shape memory effect is a reversible solid-state phase transformation. Ni-Ti SMA transform martensitically from B2 cubic austenite into monoclinic B19' martensite either directly or via rhombohedral R-phase. In the form of films they have also the potential for batch fabrication and, thus, Ni-Ti films are attractive materials for microfabrication and integration in micro-miniature systems composed of mechanical elements, actuators, sensors and electronics made on one chip. Applications? ...use your imagination...

Roll forming is the best practice for utilizing steels of 80+ ksi tensile and yield strength. As superior roll forming, we use world class materials under the SAE J2340 Ultra High Strength steel specifications. Our ability to over bend angles combined with the progressive nature of the process makes roll forming ideal for producing high quality, low cost in weight, ultra high strength steel components. Materials that are up to 7 times stronger than conventional steel reduce weight and in many instances reduce cost because the gage drop can often be enough to overcome the increase cost per pound for the higher grade materials.

Shock along Fe-bcc(001), piston velocity=417m/s Shock waves were initiated by a 'momentum mirror' (B.L. Holian and P.S. Lomdahl, Science 280, 965 (1998)), which specularly reflects any atoms atoms reaching reaching the face of of the perfectly flat infinitely massive piston (left) moving at a piston velocity. The resulting shock waves in the iron single crystal moves (from left to right) along the (001) direction in the initial bcc structure (gray). Above the threshold for the structural transformation (about 15GPa, about 10 percent uniaxial compression, or about a piston velocity of 5 percent of the longitudinal sound velocity) into the close-packed structure (red) many grains of the close-packed material nucleate in a displacive manner (martensitic-like) within the uniaxially compressed bcc structure (blue). Crystallographic different oriented grains are separated by grain boundaries (yellow). Depending on the shock strength the transformed region can be a mixed phase region and the resulting shock wave structure is a split two-wave structure consisting of an elastic precursor and a slower transformation wave. The initial nucleation takes place along the (bcc011) close-packed planes transforming into the close-packed planes of the close-packed material. The comparison of the nucleation process for three different shock strength (increasing from left to right in the movie) is shown in the last movie where only atoms with a lateral displacement larger than about 1/6 of the nearest neighbor distance are shown. The samples consist of aprox 8 million atoms (i.e. 40.2nm x 40.2nm x 57.4nm) and was simulated for 8.76ps.

My 30 watt ULS powered Laser table with 54x30x9 dimensions. Cost about $6000AUD Still a few things to add like a rotary attachment and a martensitic stainless steel top. Update--- I have finished the rotary attachment which works fairly well but still needs a little bit of work to be done to it and the stainless steel top is in place. The music is Andy McKee's 'Into the Ocean' and Catherine D'uc for the end one but I can't remember the name of that one.

Martensitic transformation at low temperatures. Cubic iron-nickel alloy nano-particles (only half of the sample is shown in order to see the interior) undergo a martensitic transformation (first movie) from the high temperature fcc austenitic phase (red) into the low temperature bcc martensitic phase (green) (due to technical reasons the surface is green or blue depending on the orientation of the surface). The heterogeneous nucleation starts at defects like corners and grows into the interior of the nano-particle with a fraction of the sound velocity (that is, the growth velocity depends on the crystallographic direction.) with a transient mixed phase region having a needle-like pattern. The final structure is twinned and can undergo a transformation back to the original austenite structure (second movie). The sample contains one million atoms (edge length=24nm) and was simulated for 67.5ps.

I open and consume a canned German cheeseburger that I ordered on the internet.

the knife i made over the last year or so. its large! the blade is 93x raindrop RWL34 and PMC27 grade martensitic stainless damascene, the blade was lightly forged so that the rake angle cuts through the lamination of steels to reveal the pattern.

Reflectogenesis........... Is the difference between us and Neanderthals the fact that we had the technology of Mirrors? Recent discovery says that Neanderthals had the genes for language - so did the technology of mirrors act as a catalyst for language - by giving rise to the spread of the concept of 'self' or 'I' and so spark the evolution or creation of language by affecting the expression of those genes in other species than Neanderthal. i.e neanderthals evolved without mirrors (so their language genes were not expressed because they did not have a strong expression of 'self' through mirrors and so language and social construct) so didnt develop language in the same way that those humans who displaced them. {A bit like the 'wheel' in South America} So is there a 'wheel' gene? Just how important are mirrors in the development of modern human. Is it the driving force behind bi-lateral brain abstract thought,consciousness and self. Maybe mirrors produced a phase transformation in the brain which produced consciousness - that is to say hat consciousness emerged from the use of mirrors. Analogous to a martensitic transformation in metals. Do mirrors present an incongruous visual problem at the same time as stimulating the discovery of the first person in association with ones own body parts? Note that recent discoveries show the sense of self to be linked to ones own visual appearance. Note also the use of mirrors in teaching speach to deaf people by association of movement to sound. Ist der Unterschied zwischen uns und Neandertalern der Tatsache, die wir die Technologie der Spiegel gehabt haben? Neue Entdeckung sagt, dass Neandertaler haben gehabt die Gene für Sprache - so hat gemacht die Technologie der Spiegel als ein Katalysator für Sprache - durch Verursachen der Ausbreitung vom Begriff von „Selbst" oder „ich" handelt, und zündet deswegen die Entwicklung oder die Schöpfung der Sprache durch Beeinflussen des Ausdrucks von den Genen in anderer Spezies als Neandertaler. ich. E, das Neandertaler ohne Spiegel entwickelt haben (deshalb wurden ihre Sprachengene weil nicht ausgedrückt Sie haben keinen starken Ausdruck des „Selbst" durch Spiegel gehabt und so Sprache und sozial baut) deshalb didnt entwickelt Sprache im gleichen Weg, den die Menschen die sie versetzt haben. {Ein Bit wie das „Rad" in Südamerika} So ist dort ein „Rad" gen? Nur, wie wichtig Spiegel in der Entwicklung modernen Menschen sind. Ist es die treibende Kraft hinter bilateralem Gehirn und zieht hat gedacht ab. Überreicht es ein widersinniges visuelles Problem gleichzeitig, als die Entdeckung von der ersten Person in Vereinigung mit derjenig anregend, besitzen Körperteile? Merkt, dass neue Entdeckungen den Sinn des Selbst zeigen, zu derjenig verknüpft zu werden, besitzen visuelle Erscheinung. Merken Sie auch den Gebrauch der Spiegel in Lern speach zu tauben Leuten durch Vereinigung der Bewegung, zu ertönen. ¿Está la diferencia entre nosotros y los Neandertales el hecho que tuvimos la tecnología de Espejos? El descubrimiento reciente dice que Neandertales tuvieron los genes para el idioma - tan hizo la tecnología de espejos actúa como un catalizador para el idioma - ocasionando la extensión del concepto del "ser" o de "yo" y tan chispea la evolución o la creación del idioma afectando la expresión de esos genes en otra especie que Neandertal. neandertales yo.E evolucionaron sin espejos (tan sus genes de idioma no fueron expresados porque Ellos no tuvieron una expresión fuerte del "ser" por espejos y tan idioma y social construye) tan didnt desarrolla el idioma de la misma manera que esos humanos que los desplazaron. ¿{un poco como la "rueda" en Sudamérica} Tan está allí un gene de "rueda"? Justo cuán importante son los espejos en el desarrollo del humano moderno. Es la fuerza motriz detrás de cerebro bilateral y abstracto pensó. ¿Presenta un problema visual incongruo a la vez que estimulando el descubrimiento de la primera persona conjuntamente con unos posee las partes del cuerpo? Note que los descubrimientos recientes muestran la identidad para ser ligado a unos posee la apariencia visual. Note también que el uso de espejos en el speach docente a personas sordas por la asociación del movimiento para sonar. 是在我们和 Neanderthals 之间的差异我们有镜子的技术的事实？ 近来的发现说 Neanderthals 为语言有基因 - 这样做镜子的技术为语言充当一种催化剂 - 通过引起概念的扩张 ' 自己 ' 或者 ' 我 ' 所以通过在其他种类中影响那些基因的表达激起语言的发展或者创造较之穴居人。即穴居人没有镜子发展（这样他们的语言基因没有被表达因为他们没有强表达 ' 自己 ' 通过镜子所以语言和社会的构思）这样 didnt 在同样的路线发展语言那取代他们的那些人类。{ 有点喜欢 ' 轮子 ' 在南美洲 } 这样在那里 ' 轮子 ' 基因？ 只是怎样重要是在现代人类的发展中的镜子。是它在双边脑子后面的推动力和提取想法。做它礼物在作为拿着一自己的身体零件在联合中刺激第一人的发现的同时的一个不适宜视觉的问题？ 请注意，近来的发现显示到一副自己视觉的外表有待连接的自己的意义。 也在通过运动的协会教 speach 学聋的人听起来方面注意镜子的使用。
