A transformation kinetic model and its application to CuZnAl shape memory alloys—II. Non-isothermal conditions
Eon-Sik Lee,Young G. Kim +1 more
TL;DR: In this paper, it has been demonstrated that the activation energies of the solid state transformations obeying the modified Johnson-Mehl-Avrami/Austin-Rickett type kinetic equation can be determined from both the Kissinger method and the Ozawa method.

Evolution of Principle and Practice of Electrodeposited Thin Film: A Review on Effect of Temperature and Sonication
TL;DR: In this article, the evolution of thin films from surface engineering, their deposition methods, and important issues are discussed. And the effects of temperature and sonication on the structure and morphology of the deposits and nucleation mechanisms, residual stress, and mechanical properties has also been covered briefly.

Distortion in 100Cr6 and nanostructured bainite
TL;DR: In this paper, the effect of heat treatment conditions on the degree of distortion due to phase transformation is established, and it is shown that distortion can be engineered by invoking thermodynamic calculations and employing a neural network.

Mesoscale kinetics produces martensitic microstructure
Oliver Kastner,Graeme J. Ackland +1 more
TL;DR: In this paper, the authors used a binary Lennard-Jones potential to describe a square-to-hexagonal transformation by shear-and-shuffle, and observed the nucleation of wedge-shaped, twinned martensite plates.

The study of low-temperature austenite decomposition in a Fe-C-Mn-Si steel using the neutron Bragg edge transmission technique
TL;DR: In this article, a new technique based on the study of the transmitted neutron beam has been developed to study the low-temperature decomposition of austenite in a 0.4 wt.% C-3 wt.
