An ideal model for stress-induced martensitic transformations in shape-memory alloys [PDF]
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.

Validity for a phase-field model on the martensitic phase transformations [PDF]
We show the existence of global-in-time solutions to an initial-boundary value problem in one space dimension of a phase-field model on the martensitic phase transformations, which consists of the equations of degenerate and a nondegenerate nonlinear parabolic equation of second order.

A Phase Field Model for Martensitic Transformations [PDF]
AbstractThe martensitic transformation is described using a phase field model which is in mathematical terms the regularization of a sharp interface approach. In this work, up to two martensitic orientation variants are considered. The evolution of microstructure is assumed to follow a time dependent Ginzburg‐Landau equation. The coupled problem of the

Microstructural characterization of AISI 431 martensitic stainless steel laser-deposited coatings [PDF]
High cooling rates during laser cladding of stainless steels may alter the microstructure and phase constitution of the claddings and consequently change their functional properties.

Omega transition accompanied by mechanically-induced twinned martensite
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.

The role of phase interface energy in martensitic transformations: a lattice Monte-Carlo simulation
To study martensitic phase transformation we use a micromechanical model based on statistical mechanics. Employing lattice Monte-Carlo simulations and realistic material properties for shape-memory alloys (SMA), we investigate the combined influence of ...
