Microstructural and Mechanical Properties of Ti3SiC2-CNF Composite Materials by PM

This study aims to investigate the microstructure and mechanical properties of Ti3SiC2-carbon nanofiber (CNF) composite materials by powder metallurgy (PM). Ti, SiC, graphite CNF powders were used produce Ti3SiC2-CNF materials. After formulated ground in a ball mill, milled pressed at 500 MPa pressure then sintered 1150 °C, 1300 °C 1450 °C. SEM-EDS XRD analysis examine phase formation. Hardness test was carried out with help Vickers hardness apparatus. The densities measured Archimedes’ principle. Three-point bending performed determine transverse rupture strength (TRS) samples. SEM images showed that samples have kink band nanolaminar structures typical MAX presence Ti3SiC2 detected also supports this situation. Depending on sintering temperature, there changes microstructure, density
