The flow-stress data of steel 55SiMnVB has been determined at 900—1200℃ and strain rateof 1--100s~(-1), true-strain of 0.08--0.8. An available evaluated formula on the flow-stress has been obtained by means of non-linear regression. It can express clearly thephysical process of hot-deformation. Key words:  flow-stress      steel 55SiMnVB      evaluated formula      hot-deformation      Received:  18 May 1989      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/Y1989/V25/I5/119 1 大森正信.高温部份,日本铁钢协会监修,铁钢热加工金属学,经田连会馆三阶,东京,1982:77 2 永吉日出男.日本铁钢协会监修:铁钢热加工金属学,高温部份,东京,1982:1 3 Dieter G E.
