Microstructural Study of Devitrified Amorphous Alloys

Abstract

Several amorphous alloys were subjected to thermal processing subsequent to their rapid solidification. These alloys have been characterized utilizing metallographic (optical, TEM, and SEM) and x-ray methods. Also, mechanical property evaluations have been made. The alloys exhibit extremely fine grain size; some have a high degree of preferred orientation and second-phase precipitates in the submicron size range. Most have good modulus, high yield and ultimate strength, high reduction in area but limited percent elongation.
