Microstructure and texture development in AISI430 ferritic stainless steel
… range, AISI 430 alloys undergo a partial phase transformation of ferrite to austenite when subjected to hot rolling temperatures. Consequently, the alloys consist of ferrite and austenite during processing. The presence of austenite and ferrite influences the microstructure evolution and texture …

An analysis of ferromagnetic shape memory alloys produced by melt spinning, sputtering and pulsed laser deposition.
… magnetic field has been shown to affect the transformation strain on cooling. Ni-Mn-Ga alloys form a Heusler (L21) lattice which, on cooling, undergoes a diffusionless transformation beginning at the martensite start temperature Ms into either a tetragonal ororthorhombic martensite, both of …

Soft Self-assembly and Densest Packings in Colloidal Models
… phase transitions, focusing on the kinetics of a diffusionless transformation between two crystal phases. Experiments are conducted on a monolayer of magnetic and nonmagnetic spheres suspended in a thin layer of ferrofluid and exposed to a tun- able magnetic field. A theoretical model of hard …

Theory and significance of retained austenite in steels
… following the bainite and martensite phase transformations have been examined, together with the influence of retained austenite on the properties of low alloy steels. It was found that the upper and lower bainite transformations are separate reactions, although both involve a displacive …
