半固态Y112铝合金的压缩变形力学行为
摘要
采用Gleeble-1500热模拟机
研究了基于半固态等温热处理技术制备的Y112铝合金
在不同变形温度和变形速率下的半固态压缩变形力学行为。结果表明
当压缩应变低于0.8时
随着压缩应变的增加
合金的半固态压缩应力首先快速增加
然后快速减小
最后逐渐保持不变;同时
在不同变形温度和变形条件下
合金在压缩应变近似为0.07时均可获得最大的半固态压缩应力;此外
随着变形温度降低或变形速率升高
合金的半固态压缩变形应力增加。
Abstract
The compression deformation behavior of semi-solid Y112 aluminum alloy manufactured by semi-solid isothermal treatment has been examined by means of Gleeble-1500 thermal-mechanical simulator in the conditions of different deformation temperatures and different deformation rates. It is found that when the compression strain is less than 0.8
compression stress of semi-solid aluminum alloy is firstly rapidly increased then rapidly decreased with the increase of compression strain. The maximum compression stress of semi-solid aluminum alloy can be observed with the compression strain approximately 0.07 at both different deformation temperaturse and different deformation stresses. In addition
the compression stress can be increased with decreasing in deformation temperature or increasing in deformation rate.
