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.
