摘要
根据喷射成型的工艺过程特点， 研究了喷射成型制备的高硅铝合金圆锭凝固组织。结果表明： 喷射成型过程中， 在沉积坯件的上表面存在一个有一定尺寸的液态金属熔池； 沉积坯件的凝固组织与粉末凝固组织有明显差别： 沉积坯件整体上呈逐层凝固，
Based on the characteristic of spray forming process, the solidification progress of the Al 23Si 5Fe alloy billet made by spray forming process was studied. The results showed that there is a metal melt pool on the top surface of the preform in the spray forming process, the microstructure of the over sprayed powders and the preform are different, namely the microstructures of the preform change in different regions corresponding to different heat input and output rates.
