Al-0.53Zn合金近快速定向凝固条件下的胞晶间距选择
, PP. 1267-1272
Keywords: Al-Zn合金,近快速定向凝固,胞晶间距,历史相关性
Abstract:
利用Bridgman装置考察了Al—0．53Zn单相合金在近快速定向凝固条件下的胞晶间距选择规律．结果表明在给定的温度梯度下，随着生长速度的增大，定向凝固组织均为胞状晶，胞晶间距λ的分布存在一个较宽范围，其最大、最小及平均间距随生长速度v变化的实验规律可表示为λmax＝948．51v(-0.4961),λmin＝661.16v-0.5015,KGT理论模型较好地预言了近快速定向凝固条件下胞晶平均间距选择的实验规律.台阶变速实验表明，胞晶平均间里的选择具有显著的历史相关性.
