AZ91합금의 조직(組織)과 시효특성(時效特性)에 미치는 Ca 및 Si의 영향(影響)
Effects of Ca, Si on the Microstructure and Aging Characteristic of AZ91 Alloy
초록
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
