 | Martensitic Transformations, Part I Lecture on the nature of martensitic transformations in steels and other materials. In this part I we examine the characteristics of martensite. In part II we explain these in terms of the crystallographic theory of martensite. The video is particularly relevant to those studying the physical metallurgy of steels www.msm.cam.ac.uk HKDH Bhadeshia 2011年04月24日再生回数 3421 |
 | Martensitic transformation A movie of martensitic transformation in Fe-0.18C-0.2Si-0.9Mn-2.9Ni-1.5Cr-0.4Mo wt% steel, using confocal laser microscopy. The time and temperature are indicated on the left hand corner. The contrast arises from the displacements caused by the phase change from austenite to martensite. The movie has kindly been supplied for educational purposes by Professor Toshihiko Koseki of Tokyo University. The PDF file showing the crystallographic orientation of the different variants of martensite can be obtained from www.msm.cam.ac.uk and more information on martensite at www.msm.cam.ac.uk 2011年06月30日再生回数 6817 |
 | MatE115 Crystal Project - Martensite by Lucas T. 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. PS Just noticed that after uploading to YouTube, some of the text is kind of hard to read. Original video files are available upon request. 2008年10月13日再生回数 5567 |
 | Twins and Martensite The development of improved metallic materials is a vital activity at the leading edge of science and technology. Metals offer unrivalled combinations of properties and reliability at a cost which is affordable. They are versatile because subtle changes in their microstructure can cause dramatic variations in their properties. For example, it is possible to buy commercial steel with a strength as low as 50 MPa or as high as 5500 MPa. They can be made with a microstructure which is finer than that of carbon nanotubes. An understanding of the development of microstructure in metals, rooted in thermodynamics, crystallography and kinetic phenomena is essential for the materials scientist. The majority of the 1.4 billion tonnes of metals produced annually are the result of developments within the last ten years HKDH Bhadeshia Producer: HKDH Bhadeshia Cameraman: Brian Barber Camerawoman: Carol Best 2011年04月24日再生回数 820 |
 | The Ballad of Tempered Martensite From the same people who brought you the hit single, "Ferromagnetic Funk Fluid," we are proud to present our lastest endeavor, "The Ballad of Tempered Martensite." Based on modern civilization's most fundamental alloy, this song tells the epic tale of the many microstructures of quenching and tempering steel in 3 parts. Join us in exploring the microstructures of pearlite, martensite, and tempered martensite through song! This version was recorded live for the Cal Poly 2011 ASM banquet. 2011年05月29日再生回数 584 |

 | Crystallography of Martensite The first of two lectures by Professor Harry Bhadeshia on the crystallography of martensitic phase transformations. The corresponding lecture notes, slide presentations and other materials can be found at www.msm.cam.ac.uk This is one of a series of lectures on crystallography. 2011年04月29日再生回数 754 |
 | Martensite and Bainite: Bain Correspondence This movie shows two adjacent Cubic-F unit cells of austenite, with a body-centred tetragonal (bct) unit cells of austenite highlighted by colouring some of the lattice points in red. Notice that the body-centred cell is simply another representation of austenite. The relationship between the Cubic-F and bct cells is known as the Bain Correspondence. It is important because an appropriate compression applied along the z-axis together with a uniform expansion along the x- and y-axes would convert the bct cell of austenite into the body-centred cubic or body-centred tetragonal cells of martensite, bainite or Widmanstatten ferrite.

 | Characteristics of Martensite in Steels Red hot steel is austenitic. If cooled sufficiently rapidly, it transforms without diffusion into martensite. The characteristics of martensite are explained in this lecture which should be useful to anyone interested in physical metallurgy and steels.
