The Effect of Heat-Treatment on Youngs Modulus, Damping, and Microhardness of SiC/Ti-15-3
Mechanical and physical properties of a laminated, continuous SiC-fibre-reinforced Ti-15V-3Cr-3Al-3Sn (Ti-15-3) composite were analysed. The dynamic elastic modulus and damping of specimens with both unidirectional and cross-ply laminates were measured with the PUCOT (piezoelectric ultrasonic composite oscillator technique). The values of density, elastic modulus, and damping were evaluated with respect to heat treatment of the specimens. Metallographic examination was also done on the specimens to assess any changes in the microstructure in terms of changes in the mechanical or physical properties.
