The Influence of Extrusion on Crystallization of Amorphous Ti-43at%Cu powder prepared by Mechanical Alloying

Abstract

The influence of extrusion on crystallization of amorphous was investigated on amorphous Ti-43at%Cu powder prepared by mechanical alloying. The crystallization behavior is observed by X-ray diffraction method and differential thermo analysis. The crystallization is accelerated with increasing of the extruding pressure at the temperature close to the crystallization starting point.
However. at the temperature lower than the crystallization starting point.the influence of extrusion is not clear.
