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 tem... 

利用场发射电镜及能谱仪研究了取向电工钢薄、厚板坯铸锭中不同区域的析出相差异,确定了MnS、AlN及Fe3C的析出顺序和形貌特征。结果表明AlN以先析出的MnS为形核核心,形成粗大微米级的复合析出相。针状Fe3C既可以在复合析出相表面形成也可以在基体中单独出现,主要受冷却速度的影响。在1250℃保温1～2 h,AlN、Fe3C均可完全回溶,但部分MnS仍不回溶。MnS尺寸随着保温时间延长而增大。导致热轧板中沿轧向分布的粗大MnS,减弱了粒子钉扎力。 Precipitates in thin and thick slabs of electrical silicon steel were investigated by means of field emission SEM and EDS analysis.The precipitation sequence and the morphology of MnS,AlN and Fe3C particles were identified.AlN particles are observed to be nucleated on surface of MnS forming micron-meter-sized complex particles.Acicular Fe3C can precipitate on surface of the complex MnS/AlN particles or directly from matrix depending on cooling rate of the slabs.After holding at 1250 ℃ for 1-2 h,...
