Abstract
A steel fibre reinforced aluminum metal matrix composite (AIMMC) has been tested for use as a local reinforcement in the combustion bowl edge region of automotive pistons for diesel engines. The piston bowl edge is subject to complex superimposed high frequency mechanical (HCMF) and high and low frequency thermomechanical (TMF) fatigue loading with peak operating temperatures reaching up to 440°C. In this study, dilatometric thermal cycle experiments have been carried out to assess the thermal strain/ expansion characteristics of the AIMMC. Finite element modeling (FEM) of the bench test conditions has been carried out on microstructural AIMMC models, extracted using x-ray micro-tomography techniques, to assess the internal inelastic strain trends relative to the specimen thermal strain/ expansion results.
