Deformation and martensitic transformation

Analysis of deformation induced martensitic transformation in stainless steels

Many studies monitoring the formation of martensite during the tensile deformation of austenite report data which are, in principle, affected by both the applied stress and the resulting plastic strain. It is not clear in these circumstances whether the transformation is stress induced (i.e. the stress provides a mechanical driving force) or whether the generation of defects during deformation ...

Deformation-Induced Martensitic Transformation in Cu-Zr-Zn Bulk Metallic Glass Composites

The microstructures and mechanical properties of (Cu0.5Zr0.5)100−xZnx (x = 0, 1.5, 2.5, 4.5, 7, 10, and 14 at. %) bulk metallic glass (BMG) composites were studied. CuZr martensitic crystals together with minor B2 CuZr and amorphous phases dominate the OPEN ACCESS

Driving force for martensitic transformation in steels

recently determined LVl~ to be 111918 J mol-I at temperatures below 1000 K, and pointed out that their experimental data were free from various 'intercept effects' which had dogged earlier investigations. Similarly, for T<1000K, they deduced '\~s=51.44Jmol-IK-I. There seem to be no data on the variation of LVl~ or ,\~s as a function of x. However, Lobo and Geigerl found that LVll: and ,\S~S do ...
