摘要

摘要:以ZL114A合金为研究对象，采用铸造合金熔体凝固特性分析仪对该合金进行动态凝固应力测试，研究了铸造工艺参数对ZL114A合金应力框铸件应力影响。实验结果表明，ZL114A合金凝固过程对应力框铸件的应力状态及变化有重要影响。随着浇注温度的升高，粗杆最小应力值和最终应力值增加。冷却速率增加，粗杆最小应力值变小，最终应力值增加。与未变质试样相比，经Sr变质处理后，粗杆最小应力值减小，最终应力值增加。

Abstract

Abstract:The dynamic solidifying stress of ZL114A alloy was tested by stress testing equipment in this work.The effect of casting process parameters on solidifying stress of stress frame specimen was studied.The testing results show that the solidifying process has an important effect on the stress state and change of stress frame specimen with ZL114A alloy.The minimum stress value and final stress value of coarse bar in stress frame specimen increase with increasing of pouring temperature.The minimum stress value decreases and finial stress value increases with increasing of cooling rate.Compare to the specimen with unmodified treatment

the minimum stress value decreases and finial stress value increases for the modified ZL114A alloy with Sr
