Abstract The influence of temperature, heating rate and strain rate on the tensile and yield strength of 30CrMnSi at the temperature range from 100℃ to 900℃ has been investigated. At low temperature region the performance parameters of material with a rise of temperature is dropped slowly and the heat treated condition has a great effect on the behavior of material, but the effect of elevating temperature rate can not be neglected. At high temperature region the material strength reduced greatly is not changed notably with the increase of temperature, heating rate and the heat treated condition. At the middle temperature region,the performance of material is fast dropped with the increase of temperature and the effects of the elevating temperature rate and the heat treated condition are not obvious.Correspondent: WANG Chunkui, associate professor,Institute of Mechanics, Chinese Academy of Sciences,Beijing ,100080
