【摘要】 选择黄铜、工业纯铁进行滑移带观察样品的制备。黄铜的压缩率控制在3%～4%即可,可以观察单滑移、多(复)滑移现象;工业纯铁主要观察交滑移现象,压缩率控制在5%～6%。实验课程的运行过程中,还可以选择铝合金固溶处理后的样品,采用锤击的简单形式由同学自己亲自制备滑移带样品,可以起到更好的实践锻炼作用。更多还原

【Abstract】 Brass and ingot were selected for the preparation of slip band samples.If compression ratio of brass samples is controlled within the range of 3%～4%,both of single slippage and multiple slippage phenomena can be observed.As for ingot samples,cross slippage phenomenon could be mainly observed below 5%～6% compression ratio.During experimental course performance,students can prepare slip band samples on their own with hammering of aluminum alloy processed through solution treatment,so that they can gain more opportunities for practice.更多还原
