摘　　要：在Gleeble-3500热/力模拟试验机上对HW600钢进行高温压缩试验,研究在不同试验条件下的变形抗力。试验结果表明:变形温度对变形抗力的影响最为显著,在相同的变形速率下,随着变形温度的升高,变形抗力降低;在同一变形温度下,变形速率增大,变形抗力增加;在同一变形温度、变形速率下,随着变形程度的增加,变形抗力急剧增大,真应变达到0.1后,变形抗力增加趋势变缓。The high -temperature compression test is done for HW600 steel with Gleeble -3500 thermal simulation testing machine to research its resistance to deformation under different test conditions. It is showed from result that deformation temperature has greatest effect On the resistance, and along with the temperature getting higher the resistance lowered under same deformation rate; the resistance increases along with deformation rate getting greater under same temperature; and under same deformation temperature and rate the resistance gets sharply increased with deformation extent increased; the resistance increases slowly after real strain reaches at 0.1.
