SiC–Ti layered material prepared by binder-treated powder sintering

Ti–SiC layered material was prepared by binder-treated powder metallurgy method. Ti, SiC and C powders were ball-milled and then binder treated. Mixture of the treated powder was loaded into a stainless steel mold first and followed by loading the pure Ti powder on top of the treated powder, then compacted under a pressure of 200 MPa at 165 °C with a pressing speed of 250 mm/min. The green compacts were debinded at 500 °C for 1 h and sintered at 1500 °C for 2 h under argon atmosphere. The sintering temperature was determined by measuring the phase formation temperatures between Ti, SiC and C powders, using differential scanning calorimetric method. The reaction products after sintering were analyzed. Microstructure of the prepared Ti–SiC layered material was also studied.
