摘要

以QSn7-0.2合金为研究对象

以进给比、首轮压下比、退火温度为变量因素

建立了单因素试验表

研究了不同参数对QSn7-0.2合金的晶粒尺寸的影响

并对其晶粒尺寸存在差异性的原因进行了分析。结果表明

当进给比增大时

微观组织内平均晶粒度呈现先减小后增大的趋势;当首轮压下比增大时

组织内平均晶粒尺寸变化不明显;当退火温度升高时

合金的平均晶粒尺寸略有增大。

Abstract

Effects of different processing parameters

such as feeding ratio

the first induction and annealing temperature on grain size in the QSn7.0-2 alloy were analyzed by the single factor experimental table.The origination of difference on grain size was described.The results show that the average grain size in the microstructure is decreased firstly and then increased with the feed ratio increase.However

the increase of first induction can be ignored to effects on grain size change.With increasing in annealing temperature

the average grain size is increased slightly.
