Mechanical Properties of Titanium–Titanium Boride Composites Through Nanoindentation and Ultrasonic Techniques — An Evaluation Perspective

Abstract

In this work, the mechanical properties such as elastic moduli, shear moduli, and hardness of titanium–titanium boride composites with 20% and 40% of titanium boride reinforcements were estimated by ultrasonic and nanoindentation techniques. The estimated values obtained from the both measuring techniques are compared. The composites were processed by three powder metallurgical techniques such as spark plasma sintering, hot isostatic pressing, and vacuum sintering. The composites processed through spark plasma sintering and hot isostatic pressing showed better mechanical properties compared to the vacuum sintered composites. The effects of titanium boride reinforcements and their morphological influences on the mechanical properties are also described.
