Ti/SiC Based Metal Matrix Composites by Using Self-Propagating High Temperatures Synthesis (SHS)

Popis výsledku v původním jazyce

In the present paper, Ti/SiC composite materials have been fabricated by using Self-propagating high temperatures synthesis (SHS). SHS is a well-known method for fabrication of the advanced materials in a single step process and is based on a system that involves an exothermic combustion. Titanium powder (Ti/p) with average particle size 100 µm and Silicon carbide (SiC) with 100-320 µm particle size range has been mechanically activated by attrition mill. Powder weighing has been prepared in accordance to the size of each volume fraction where the ratios for Ti/SiC are 70:30% and 60:40%. The optimal density results were achieved in the volume fraction of 70:30% at 1000ºC for 4.54 gr/cm3. The porosity test data has shown that the porosity value has been increased during the increasement of the SHS sintering temperature. The lowest porosity was produced at a volume fraction of 70:30% in a sintering temperature at 900ºC with the corresponding value 2.36%. The highest and lowest hardness value varied from 194 HV to 40 HV. The results have shown that mechanical properties of the Ti/SiC composite materials have been increased in comparison to the commercially pure titanium substrate and almost close to mechanical properties of Al/SiC composite materials.
