Transformation plasticity in titanium alpha double prime martensiteO.M. Ivasishin and R.V. Teliovich

In this paper, explanation of an exceptionally low yield strength and high plasticity of α"-martensite is given using the experimental data on martensite crystal structure of Ti-7%Mo (wt). It is supposed that as-quenched martensite microstructure is a highly nonuniform set of distorted due to compositional modulation microvolumes. Interaction between internal stresses generated in martensite modulated microstructure and external applied stresses modifies crystal lattice in a specific way, leading to a transformation induced plasticity.
