Deformation of Rapidly Solidified Ti-2Er.

Abstract

The deformation of rapidly solidified Ti-2Er has been studied over a range of temperatures from ambient ot 775C. When compared to the behavior of Ti tested under parallel conditions, the results indicate that although dispersion strengthening occurs, its magnitude is dependent on temperaute, strain rate, and grain size. Minimal strengthening is observed in fine grained materials at high temperatures, low stresses and strain rates. This behavior, combined with microstuctural observations using transmission electron microscopy, indicates a susceptibility to grain boundary sliding at elevated temperatures.
