Cu-Mn solid solution phase strengthened aluminum alloys and manufacturing method thereof

摘要

PURPOSE: for enhancing aluminium alloy Cu-Mn complete solid solutions and preparation method thereof, to minimize entire weight by being applied to the aircraft of diesel engine piston and part. ;CONSTITUTION: a kind of manufacturing method of aluminium alloy includes next step for Reinforced Cu-Mn complete solid solutions. The Cu-Mn complete solid solutions that first aluminium alloy contains first amount are provided. First aluminium alloy is put into aluminium molten metal. Aluminium molten metal casting to manufacture the second aluminium alloy. Second aluminium alloy has the Cu-Mn complete solid solutions of the second amount, less than the first amount. Comprising steps of providing the first aluminium alloy includes next step. Cu, Mn are placed in the first aluminium molten metal, and the first aluminium molten metal is poured. ;The 2012 of copyright KIPO submissions
