Research on Heat Treatment Process for New Style CuNiAl Alloy

The heat treatment process for new style CuNiAl alloy was studied.The influences of heat treatment process on the microstructure and mechanical property were studied by metal microscope,TEM and mechanical property measurement.The results show that the alloy has good mechanical property after heat treating at 890 ℃ for 30 min then furnace cooling to room temperature,the α phase,KⅡ and KⅣ phase are dominate phases.
