- Abstract
In this work, we describe the fatigue behaviour of silicon carbide (SiCP)-reinforced A359 aluminium alloy matrix composite considering its microstructure and thermo-mechanical properties. A variety of heat treatments have been performed for the 20 vol. % SiCp composite, which resulted in different strength and elongation behaviour of the material. The fatigue behaviour was monitored, and the corresponding S-N curves were experimentally derived for all heat treatments. The fatigue strength was found to depend strongly on the heat treatment. In addition, the fatigue behaviour was monitored non-destructively via the use of lock-in thermography. The heat wave, generated by the thermo-mechanical coupling and the intrinsic dissipated energy during mechanical loading of the sample, is detected by a thermal camera.
