This study demonstrates transformation-induced plasticity (TRIP) in conjunction with twinning-induced (TWIP) α + β titanium alloys by introducing metastable retained β-phase. By annealing at 850 °C followed water quenching, β-phase (∼25%) was obtained Ti–6Al–4V alloy. Stress-induced phase transformation the produced orthorhombic α′′-martensite associated (021)α′′ twinning, which significantly i...

In this study, based on the sensitivity of chemical composition fluctuation to thermodynamic parameter, which controls level stacking fault energy (SFE), a series high Cr–Mn–N twinning-induced plasticity (TWIP) stainless steels are designed by using sublattice model, and their mechanical properties micro deformation mechanism analyzed The formation twins (Mts) during makes test steel show perfe...

the dynamic behavior of three high manganese steels with very different stacking faultenergy (sfe) values (4-30 mj/m2) were studied using high strain rate torsional tests. the hotrolledmicrostructure of the steel with the lowest sfe of 4 mj/m2 consisted of a duplex mixture ofaustenite and ε-martensite, but those of the other two steels were fully austenitic. the deformedmicrostructures were stu...

Abstract Carbon is a well known austenite stabiliser and can be used to alter the stacking fault energy stability against martensitic transformation in medium Mn steels, producing range of deformation mechanisms such as Transformation Induced Plasticity (TRIP) or combined Twinning (TWIP + TRIP) effects. However, effect C beyond quasi-static tensile behaviour less known. Therefore, two steels wi...
