摘要
通过多因素正交试验，对比分析了常规热处理工艺与ＬＴＭＴ工艺所生产的硅青铜挡块性能上的差异，得出了ＬＴＭＴ工艺为较佳生产工艺，并分析研究了ＬＴＭＴ工艺参数对材料性能的影响规律，得出最佳工艺为：淬火温度９００～９５０℃，保温时间０．５～１ｈ，变形程度５０％～７０％，时效温度４５０～５００℃，时效时间３～５ｈ．
おhrough orthogonal tests,the different effects of ordinary heat treatment process and LTMT process on the property of damblock material of silicon bronze were described in this paper.As a result,the LTMT process was proved to be feasible.The optimum parameters of this process were obtained.They were:solid solution temperature 900～950 ℃,solid solution time 05～1 h,deformation ratio 50%～70%, aging temperature 450～500 ℃,aging time 3～5 h.
