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

怎么不把文章全文都帖出來交流一下呀，謝謝。

再談拉絲機的新發(fā)展
是啊

要是有全文多好！

不但能接觸到心的技術還能溫習自己的專業(yè)英語！

等待著樓主的再次奉獻！

清冽支持樓主把 原文資料都共享給大家.謝謝您了

都是牛人呀

沒有原文的話最好別在這里貼

看著著急沒辦法

看起來困難。

看來學好英文真是太重要了。

很不錯
