The effects of the deformed temperature, determed rate and deformated degree to flow stress were analysed. At the same time, non-linear regressions to mathematical models with different structure were conducted. Through comparision and analysis, mathematical models with higher fitting accuracy were proposed.Correspondent: GUAN Kezhi, professor, Institute of Mechanical Engineering, University of Science and Technology Beijing, Beijing 100083 Key words:  brass      flow stress      mathematical model      cam plastometer      Received:  18 July 1996      Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1996/V32/I7/749 1AM著,林治平译．金属与合金的塑性变形抗力手册．北京:机械工业出版社,1984:3322 管克智,周纪华,伦怡馨．钢铁,1989;24(9):273 刘志万．实验数据的统计分析和计算机处理．合肥:中国科学技术大学出版社,1989:1224 吴继庚．实用数值计算方法与程序．北京:冶金工业出版社,1991:129 [1] Xiangru GUO, Chaoyang SUN, Chunhui WANG, Lingyun QIAN, Fengxian LIU.
