摘　　要：开发新型Al-Mn40中间合金,配料选用A00级纯铝锭与Mn粉,在中频炉中熔炼;获得了成分合格,金相观察组织清晰洁净的中间合金。实验过程中,通过适当提高融入温度,提高了Mn粉的融入速度,但Mn粉出现了少量烧损。通过提高模温、延缓冷却速率,降低了缩孔尺寸。The new Al-Mn40 intermediate alloy was developed using A00 aluminum ingot and Mn powder, melting in medium furnace. The intermediate alloys have qualified components and good microstructure. During the experiment, the infusing speed of Mn powder was increased by appropriately increasing integration temperature. But there was a small amount of Mn powder burning. The size of shrinkage was reduced by increasing the mold temperature and slowing cooling rate.
