Effect of Stress State on Primary Creep Behavior of PM Al-Mg-Sc-Zr-SiC p Composite
Abstract
Primary creep strain is very important for components that are limited by total creep strain. a common design practice is to define the maximum stress that results in certain total creep strain in a particular application. the stress state also appears to play a major role in case of primary strain in many powder metallurgy (PM) aluminum alloys and composites. We have studied the effect of stress state on primary creep behavior of PM Al-6Mg-1Sc-1Zr-10 vol. % SiCp composite designed for high temperature applications. Composite was tested under tension, compression and shear to evaluate the primary creep behavior under different tests conditioned. It was observed that primary creep strain varies significantly with stress state.
