Abstract

The thermal cycling behavior of a creep-resistant AE42 alloy, AE42 alloy reinforced with 20 vol% saffil short fiber as well as various volume fractions of saffil short fiber and SiC particulate was examined in the temperature range of $30-350 ^o C$. The plastic deformation due to internal thermal mismatch stresses above $250 ^oC$ increases and coefficient of thermal expansion decreases with increasing volume fraction of SiC particulates. The only microstructural change observed after thermal cycling is an increased precipitation in the matrix.
