摘要

采用振动法制取铝合金颗粒。探索了各工艺参数对颗粒尺寸、形状及冷却速度的影响；分析了颗粒的金相组织，估算了颗粒材料的凝固速度；采用真空热压技术和热挤压技术，将颗粒制成了试验棒材，测试了材料的力学性能。测试结果表明：采用颗粒制造工艺制取的材料的力学性能优于同成分的铸造材料的１～２倍，是一种有发展前途的材料制造加工工艺。

Abstract

Alalloy particulates were prepared by vibration. The effect of different parameters on particulate size

shape and cooling rate is explored. The microstructure and solidification rate of the particulate are analyzed. The rod is made of the particulates by vacuum hot press and thermal extrusion. The mechanical properties of the rod are determined. The mechanical properties of the rod made of the particulate are as higher as that of conventional cast rod in 2￣3 times.
