Abstract
A Study on the Interface Behavior of Aluminium Alloy Matrix Composites Reinforced with W Fiber. In this study the tungsten fiber reinforced 7072 aluminium alloy martrixcomposites were fabricated using vacuum hot press. The fiber has been aligned on the aluminium alloy sheets and these sheets were bonded with diffustion at 873K and 49Mpa. The behaviors of interface layer and mechanical properites have been investigated as a function of holding time at 873K. Several compounds were formed at the interface layer. These compounds were growing in propotion to holding time. XRD analysis showed that these compounds were
7072Al 을 기지로하고 W 섬유를 강화재로 사용하여 진공 hot press 에서 복합재료를 제조한 후 시간을 변수로 열처리하여 처리시간에 다른 계변층의 변화와 이에 따른 기계적 성질의 변화를 비교 검토하였다. 각종기기(SEM, XRD 등)를 사용하여 계면층을 분석한 결과 처리시간이 10시간까지는 계면층의 변화는 미미하였으나 10시간을 초과하면서 계면층은 현저히 성장하기 시작했다. 이 계면층은 취성이 있는
