Results showed that the increase in smooth or notohed fatigue limit amounts to 57 or 200% respectively. The fatigue sensitivity to notch may be greatly reduced,and so the q value may become negative. During surface rolling of hcp Mg alloy,the plastic deformation and strengthening may be carried out by the way of slip and twin.The high compressive residual stress is favourable to improve the notched fatigue hmit and to modify the fatigue sensitivity to notch. The plastic deformation strengthening may contribute to develop the benificial behaviour of the compressive residual stress.Correspondent: FENG Zhongxin,(Xi'an Jiaotong University,Xi'an 710049) Key words:  Mg alloy      fatigue sensitivity      fatigue strength      plastic deformation      residual stress      Received:  18 September 1994      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/Y1994/V30/I9/422 1黄明志,石德珂,金志浩.金属力学性能.西安:西安交通大学出版社,1986:1552张建中,冯忠信,张定銓,胡志忠,陈新增,胡奈赛.西安交通大学学报,1982;16(1):233周惠久,全达曾,邓增杰,陈黄浦．西安交通大学学报,1982;16(2):14张良运,张振洪,李春霖,涂铭旌,金敏洲.机械工程材料,1992;16:345西安交通大学,上海交通大学.金属机械性能.北京:中国机械工业出版社,1965:1876PompA,HempeLM．ArchEisenhttenwes,1950:2l:537WiegandHempol,TolaschG．Harterei-TechMitt,1967;22S:2l38俞德刚,王育烽,郑经,沈甫法.金属热处理学报,1984;51:219冯忠信,张建中,陈新增.西安交通大学学报,1988;22:10710冯忠信,张建中,陈新增,机械工程学报,1990;26:3,7911未谷茂.残余应力的产生和对策,北京:机械工业出版社,1983:28012陈新增.西安交通大学学报,1985;19(3):49: [1] DU Jinhui, BI Zhongnan, QU Jinglong.
