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．

Abstract: Through 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 0.5～1 h,deformation ratio 50%～70%, aging temperature 450～500 ℃,aging time 3～5 h.
