Wear-resistant aluminium alloy and method for working thereof.

摘要

An aluminum-alloy, which is wear-resistant and does not wear greatly the opposed cast iron or steel, and which can be warm worked, is provided by the following composition and structure. Composition: AlaSibMcXdTe (M is at least one element selected from the group consisting of Fe, Co and Ni; X is at least one element selected from the group consisting of Y, Ce, La and Mm (misch metal); Y is at least one element selected from the group consisting of Mn, Cr, V, Ti, Mo, Zr, W, Ta and Hf; a=50 - 85 atomic %, b=10 - 49 atomic %, c=0.5 - 10 atomic %, d=0.5 - 10 atomic %, e=0 - 10 atomic %, and a+b+c+d+e=100 atomic %).Structure: super-saturated face-centered cubic crystals and fine Si precipitates.
