Abstract
PURPOSE: To allow an Al-Zr-type alloy of a specified compsn. contg. Fe and Si to exhibit high heat resistance while holding high electruc conductivity and mechanical strength by casting the alloy followed by cooling, reducing work, heat treatment, cold working, etc. under specified conditions.
CONSTITUTION: An alloy consisting of Zr 0.2W1.5%, Fe and/or Si 0.1W1.0%, and the balance Al and inevitable impurities is melted, cast, and worked at a reduction ratio of 80% or more while being cooled to 200°C or below at a cooling rate of 5°C/ sec or more. Thus, a supersaturated solid soln. of Zr is obtd., and dislocation is introduced into the matrix. This alloy is then heat treated at 300W450°C for 5W200hr to form Zr fine precipitates, cold worked at 65% or more to introduce a cell structure of dislocation, and heat treated at 300W450°C for 0.5W5hr to shift the cell of dislocation to a thermally stable structure.
