Nitrogen-Induced Amorphization of BCC Type Solid Solution Alloys by Mechanical Alloying

概要

Mixtures of elemental metal powders consisting of the group 5A and 6A metals, which form the bcc type solid solution alloys, have been mechanically alloyed using the planetary ball mill in an argon and nitrogen atmosphere. The products were characterized by X-ray diffractometry, transmission electron microscopy, differential scanning calorimetry and chemical analysis. The bcc type solid solution alloys were produced by mechanical alloying (MA) in an argon atmosphere. On the contrary, amorphization by the additive effects obtained by combining MA with nitrogenation was demonstrated in the alloys consisting of the group 5A and 5A metals, the group 6A and 6A metals, and Ta_<50>Mo_<50>. The factors controlling nitrogen-induced amorphization during MA and the formation conditions of the amorphous alloys were discussed.amorphousnitrogenmechanical alloyingtransition metalssolid solution
