Al-8wt.%Fe 분말의 기계적 합금화 거동과 열적안정성에 미치는 Ce의 영향
Effects of Ce on the Mechanical Alloying Behavior and Thermal Stability of Al-8wt.%Fe Powder
초록
The effects of Ce on the mechanical alloying behavior and the thermal stability of Al-8wt.%Fe were investigated. The steady states of Al-8wt.%Fe and Al-8wt.%Fe-4wt.%Ce powders with 1.5 wt.% stearic acid as a process control agent were reached after mechanical alloying for 1000 minuties and 1300 minuties respectively at the conditions of the impeller revolving velocity of 300 rpm and the ball to powder input ratio of 50 : 1. The hardness of Al-8wt.%Fe specimen hot extruded and isothermally aged at various temperatures for up to 1000 hours decreased rapidly at 50
