In this paper, the superplastic characteristics of a 15 SiC(vol. pct) whisker reinforced Zn-22AI alloy composites, fabricated by low pressure infiltration and solute treatment after extrusion with the extrusion rate of 10:1, was investigated. The result showed that the composite exhibited a tensile elongation of 150% and a strain rate sensitivity value of about 0.33 at the initial strain rate of 6.67×10~(-2)s~(-1) and at 658 K where an appropriate amount of liquid phase was presented in the composite.

我是一名小学班主任。参加工作以来,一直担任班主任工作。刚开始的时候,花费的时间不少,耗费的精力也不少。但由于不懂科学管理,很多事情往往是事与愿违。后来在不断的反思和总结中,工作经验逐渐丰富起来,班主任工作相对来说就比较得心应手了。下面,我就从五个方面把自己在班级管理工作中的具体做法做一下简单的总结,以飨读者。 一、在“德”上作垂范 小学低年级,尤其是一年级的孩子,刚刚摆脱了学前那种“手
