In this work, the variant selection of martensite in a stainless maraging steel was investigated by electron backscattering diffraction and new protocol parent phase reconstruction. The reconstruction enables digital austenite reversion into prior microstructure provides information from large number grains. It found that strong occurred when grains were significantly refined annealing or sever...

the pseudo-elastic behavior of shape memory alloy (sma) truss and cantilever beam are investigated. brinson’s one-dimensional material model, which uses the twinned and detwinned martensite fractions separately as internal variables, is applied in the algorithm to establish the sma stress-strain characteristics. this material model also incorporates different young’s modulus for austenitic and ...

The effects of starting microstructure and intercritical annealing temperature on the phase-transformation kinetics microstructural evolution a prototype Fe–0.15C–5.56Mn–1.1Si–1.89Al medium-Mn third-generation advanced high-strength steel are examined. microstructures comprise 1) an as-received cold-rolled (CR) containing significant fraction ferrite tempered martensite 2) austenitized quenched...

$${\left\{112\right\}\langle {111}\rangle }_{\beta }$$ twins are observed in a superelastic β Ti-24Nb-4Zr-8Sn (wt.%) single crystal after tensile test. A careful Schmid factor analysis shows that these formed the antitwinning sense regarding classical twinning system of bcc structures. These then antitwins. Moreover, full stress-induced martensitic (SIM) transformation phase into α" martensite ...
