摘　　要：研究了不同环境温度对高牌号无取向硅钢力学性能的影响。重点研究了温度在-40~200℃范围内变化时,屈服强度、抗拉强度和伸长率的变化规律,结果表明:温度从-40℃升高到200℃时,抗拉强度和屈服强度呈先下降后上升的趋势;而当温度低于-20℃或高于140℃时,伸长率才出现明显的下降。The effects of different ambient temperatures on the mechanical properties of high grade non-oriented silicon steel were investigated,especially the variation of the yield strength,the tensile strength and elongation,when the temperature changed from-40 ℃to 200 ℃.The results showed that the yield strength and the tensile strength decreased first,then became rising.While,the elongation was decreased obviously when the temperature is lower than-20 ℃ or higher than 140 ℃.
