Abstract

The present research focuses on the comparison of Cr solubility and microstructure evolution during high-energy ball milling in Al-7at%Cr and Al-10at%Cr alloys. The nanostructured Al-based solid solution and Al₇Cr-phase precipitates were formed during milling for both alloys and the Cr increase facilitates the process. The maximum Cr solid solubility was 8.3 at% in Al-10at%Cr alloy milled for 15 h and 6.8 % in Al-7at%Cr alloy milled for 25 h. An increase in Cr solubility and improvement of powder/crystalline refinement with increasing Cr was attributed to an increased strain hardening effect.
