Abstract

In-phase and out-of-phase thermo-mechanical fatigue (TMF) experiments were conducted on 6061 aluminum alloy reinforced with 15% and 28% (volume fraction) whiskers. The mechanical behavior and deformation mechanism of both TMF were investigated and discussed. The results show that the two kinds of TMF cycling exhibited continuous cyclic softening, out-of-phase TMF loading gave rise to tensile mean stress, whereas in-phase TMF cycling led to compressive mean stress. It is also demonstrated that at an equivalent strain range, the 28% SiCW/6061Al showed higher stress range than the 15% SiCW/6061Al.
