Abstract

This paper describes the shape memory effects of TiNi fiber Al matrix (TiNi/Al) composites on enhancement of its mechanical properties: tensile and fatigue resistance. A TiNi/Al composite was processed by a powder metallurgical route. The yield stress and fatigue resistance showed that they would increase with prestrain at temperature above the austenitic finish temperature of TiNi fiber (A_f). The increases in tensile properties (yield stress) and fatigue resistance were attributed to the compressive stress field in the matrix which was induced when prestrained TiNi fibers shrank to its initial length upon heating above A_f. The predictions based on the analytical model agreed reasonably well with the experiment.
