Effects of Ca, Si on the Microstructure and Aging Characteristic of AZ91 Alloy
AZ91합금의 조직(組織)과 시효특성(時效特性)에 미치는 Ca 및 Si의 영향(影響)
Abstract
The effects of calcium and silicon on microstructure and aging characteristics of AZ91 magnesium alloy during T5 treatment was investigated. The addition of 0.88% calcium or 0.25% silicon to AZ91 alloy made dendrite cell smaller. Especially, silicon is more effectively acted as refinement of the dendrite cell than calcium. It is due to that
