Preparation of W–Al alloys by mechanical alloying

Preparation of W–Al alloys by mechanical alloying

W 1− x Al x ( x=0–0.86) alloys were synthesized by mechanically alloying the pure metal powder mixtures at designated compositions by conventional high-energy ball milling. The W–Al alloys were stable under high pressure and high temperature. The alloys were lighter than W. The hardness and oxidatio...

Beschreibung
Zusammenfassung:W 1− x Al x ( x=0–0.86) alloys were synthesized by mechanically alloying the pure metal powder mixtures at designated compositions by conventional high-energy ball milling. The W–Al alloys were stable under high pressure and high temperature. The alloys were lighter than W. The hardness and oxidation resistance of the alloys was greatly improved compared to both W and Al.
