Amorphous metallic alloys were synthesized by the methods of rapid quenching and by mechanical alloying. In contrast to rapid quenching, mechanical alloying is a new process in producing amorphous alloys. In this paper we wilt report the amorphization of Ti-Cu, Hf-Cu, Hf-Ni and Fe-Ni-B alloys. The crystallization behaviour of these amorphous alloys was examined by DTA measurements with different heating rates in the range from 1 to 80 K / rain. The data of mechanically alloyed powders will be compared with those of rapidly quenched materials. Further characterizations were done by X-ray diffraction, SEM and EDAX analyses. In general, the examined amorphous materials prepared by mechanical alloying or rapid quenching show very similar properties.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
