摘要: 研究了经室温拉变形后的纯铜包覆Q195 钢的不同线径的线材的显微组织及力学性能。结果表明,显微组织自原
始的等轴晶变为细长条纤维状,纤维长度与形变量的平方近似地成正比,纤维直径与形变量近似地成反比。经室温拉变
形的包覆线材的抗拉强度,随形变量增大而增大,与形变量平方根呈直线关系;但延伸率降低,延伸率波动偏高与晶界融
合及Q195 钢的渗碳体球化现象吻合。根据原始纯铜和Q195 钢的抗拉强度值,可以用复合材料强度的混合法则来近似
地预测不同线径的包覆线材的抗拉强度。

Abstract : The micro structure and mechanical properties of pure copper clad Q195 steel wires in different diameters by drawing at room temperature were studied in this paper . The results show that the micro structure of the cladding wire by drawing at room temperature is vimineous grain which was drawn from prime equiaxed grain. The fibril length is in direct proportion to square root of deformation and the fibril diameter is in inverse proportion to deformation approximately. The ultimate tensile strength of the cladding wire by drawing at room temperature goes up in direct proportion to square root of deformation, and the elongation comes down.  A little increment of the elongation of the cladding wires is a coincidence of partial grain boundary amalgamation and sphericized cementite in Q195 steel . Based on the original values of  the ultimate tensile strength of prime pure copper and Q195 steel , the ultimate tensile strength of  the cladding wires in different diameters can be doped out by mix principle of composite material .
Key words : clad copper steel wire ; micro structure ; mechanical property

再谈拉丝机的新发展
是啊

要是有全文多好！

不但能接触到心的技术还能温习自己的专业英语！

等待着楼主的再次奉献！

没有原文的话最好别在这里贴

看着着急没办法

看起来困难。
