真空烧结温度对Cu-Al-Mn形状记忆合金性能的影响
Effects of Vacuum Sintering Temperature on Properties of Cu-Al-Mn Shape Memory Alloy
摘要
Abstract
The Cu-12Al-2.5Mn shape memory alloy was produced by powder metallurgy technology at different sintering temperature. Consequently, the properties and microstructure of the alloy that sintered at different temperature were compared by SEM, metallographic observation, EDS, hardness test and shape memory effect test. Then the optimum sintering temperature was obtained. The results show that the bonding way between elements is metallurgical bonding and the alloying rate rises with the increase of sintering temperature, the optimum sintering temperature ranges from 850 ℃ to 900 ℃. The edge of the sample has higher hardness, and the alloy sintered at 850 ℃ and 900 ℃ has uniform and high hardness value after quenched, the hardness of the alloy sintered at 850 ℃ is HRB42.5, while the hardness of the alloy sintered at 900 ℃ is HRB 52. The shape memory effect of the alloy sintered at 850 ℃ is better than that sintered at 900 ℃.关键词
