摘要:
本文研究了快速凝固Al-Si-Ti-Pb合金中Pb的沉淀特征。在冷却速度达5～6×10~5K/s的合金条带中,透射电子显微镜(TEM)分析表明合金元素Si、Ti基本上已超固溶于α-Al基体内部,而唯有细小的Pb相颗粒仍偏聚在α-Al的微细胞晶边界,并且同α-Al基体之间保持有严格的位向关系,在电子衍射中呈现出别致有趣的双衍射花样。这些工作加深了对Pb在合金凝固过程中所具特性的认识。
Abstract:
This article studies the precipitation characteristics of PB in the fast solidification Al-Si-Ti-PB alloy. In the alloy band with a cooling speed of 5 ～ 6 × 10 ~ 5K/s, the analysis of the transmission electron microscope (TEM) shows that the alloy element Si and TI are basically super solid inside the α-Al matched body. The relationship presents a chic and interesting dual diffraction pattern in the electronic diffraction. These tasks have deepened their understanding of the characteristics of PB in the process of alloy solidification.
