Abstract
In this paper, TiNiCo/Al shape memory composites were fabricated by powder metallurgy method. TiNi and TiNiCo were used as fiber for reinforcement. To investigate the fatigue crack propagation behavior due to the compressive residual stress which exists in the composites, fatigue test was performed at room temperature and above the inverse transformation temperature A_f of TiNi and TiNiCo shape memory alloy. Results are as follows; At 363 K, both composites have lower fatigue crack propagation rate than pure matrix in the same ΔK area and the fatigue crack propagation of TiNi/Al composite is lower than that of TiNiCo/Al composite.
