本文对供应状态铝合金LY12获得超塑性进行了探讨。研究了LY12超塑予处理工艺和超塑性力学特性,采用定量金相、x射线衍射分析等手段分析了合金的显微组织,并对合金的流动充填性能进行了试验。结果表明,供应状态LY12经超塑予处理后具有一定程度的超塑性,有利于模压成形的应用。
In this paper, the superplasticity of LY12 aluminum alloy is discussed. The processing and superplasticity properties of LY12 superplasticizer were studied. The microstructure of the alloy was analyzed by means of quantitative metallography and X-ray diffraction analysis, and the flow filling properties of the alloy were tested. The results show that the supply status LY12 has a certain degree of superplasticity after being treated by superplasticizer, which is beneficial to the application of press forming.
