Abstract

Quantitative optical microscopy, ultrasonic sound velocity measurements, and transmission electron microscopy (TEM) have been used to follow the kinetics of the isothermal martensitic transformation in an uranium 1.6 at. pct gallium alloy. The results indicate that the apparent relatively slow growth of the α′ martensite plates within the β-uranium matrix actually consists of the nucleation of numerous new martensitic platelets on the martensitic plate-matrix interface and their subsequent growth at a rate similar to that in athermal martensites.
