A new paper has been published on the unusual microstructure of smectics -- liquid crystals whose molecules are arranged in layers and form ellipses and hyperbolas -- and their similarity to ...

Some organic crystals jump around when heated up. This happens because of an extremely fast change in their crystal structure. Scientists have now demonstrated that the crystals send out acoustic ...

The micrographs below show the effect of annealing at different temperatures on a sample of Fe - 0.7 wt % C steel in which martensite has been formed by quenching. Because of the low carbon content ...

DP steels contain islands of hard martensitic second phase in a ferritic matrix. Steel strength improves when the volume fraction of hard second phases increases. The formation of DP steels involves ...

The formation of MS steels involves transformation of most of the austenite structure existing during the annealing or hot-rolling process to the martensite structure by rapid quenching in the cooling ...

Crystals seen on the fine scale: River-like patterns form and change as the metal morphs A new shape-changing metal crystal is reported in the journal Nature, external, by scientists at University of ...

(a) Diagrams illustrating how columnar grains develop during the LPBF, contributing to microstructural anisotropy; (b) Stress-strain curves showing significant improvements in the mechanical ...

11 December 2006 ARAK, Markazi: Engineers of the Azarab Industries Co. have acquired the technology to produce martensite steel sheets. A press release faxed to Iran Daily by the company quoted the ...

ITHACA, N.Y. - Using the latest computer game technology, a Cornell-led team of physicists has come up with a "suitably beautiful" explanation to a puzzle that has baffled researchers in the materials ...

The transition from austenite to phases stable at lower temperatures also takes place when the material is cooled at a constant rate. The diagram illustrates the transition zone (yellow) and also ...
