Structure and Mechanical Properties of Powder Metallurgy 2024 and 7075 Aluminum Alloys

摘要

The interrelationship among processing, microstructure, and mechanical properties was investigated for commercial aluminum alloys 2024 and 7075 produced by conventional ingot metallurgy (I/M) and powder metallurgy (P/M) techniques. The objective of the investigation was to establish the degree to which the P/M approach influences the ultimate performance of high strength, precipitation hardening aluminum alloy products under fatigue limiting conditions.
