, Pullenvale,QLD 4069, Australia摘 要:The microstructure, hardness, and precipitate free zones(PFZ) of V55Ti30Ni15 alloys during heat treatment have been investigated in this study. The microstructure resulting from different heat treatment conditions has a great influence on hardness. The microstructure resulting from different heat treatment conditions has a great......
in %) alloy by the cyclic heat treatments was studied. The heat treatment scheme included a tempering at 1250°C and cyclic tempering at 1000 and 1200°C three times after solution treatment at the temperature above α phase transus followed by immediate fan cooling. The fine and homogeneous near-γ microstructure can be obtained by this heat treatment, which causes the breakdown of as-cast......
%Si-5 wt%Cu alloy(AR alloy) by a novel short duration heat treatment process. The elevated temperature(100°C) dry sliding wear behavior of an AR alloy was studied after microstructural modification using the proposed heat treatment. The study revealed considerable microstructural modifications after the heat treatment and the heat treated alloy was designated as HT(heat treatment) alloy. A higher......
