An ideal model for stress-induced martensitic transformations in shape-memory alloys [PDF]
Fracture and Structural Integrity, 2014 In this paper, a novel model for stress-induced martensitic transformations in shape-memory alloys is proposed. Accordingly, the constitutive pseudo-elastic behavior of these materials is described.

Omega transition accompanied by mechanically-induced twinned martensite
Materials Research Express, 2020 We present here an analysis on omega transition process during martensitic transformation. Martensitic transformation occurred during deformation at room temperature, avoiding the influence of auto-tempering on metastable omega phase.
