INFLUENCES OF MICRO  ALLOY AND HEAT  TREATMENT PROCEDURE ON THE HARDENING OF DJ108TI ALLOY

Abstract

Abstract: The influences of micro alloy and heat treatment procedure on the hardening of DJ108Ti alloy, which is based on the electrolytic Al Si(2 05%) Ti(0 25%) Fe(0 30%) multi component alloy, have been investigated. The results indicate that the micro alloy based on the multi component alloy makes α Al dendrites in DJ108Ti alloy refined; that the improved heat treatment procedure makes the eutectic Si phases granulated , the Fe phase refined, and the strengthening phases of Mg2Si and Al2Cu fully precipitated. The micro alloy and the heat treatment procedure harden DJ108Ti alloy and benefit the abrasion resistance of the alloy

Key words: electrolytic Al Si(2 05%) Ti(0 25%) Fe(0 30%) multi component alloy, micro alloy, heat treatment procedure, hardening
