FIELD: processing of titanium chips. SUBSTANCE: before cold-pressing, the chips are roasted in vacuum at 700-800 C for 0.5-1 h. After hot-pressing the resulting briquettes are homogenized at 1150-1220 C for 3-4 h. Cold-pressing is carried out at a pressure of 370-550 MPa while hot-pressing, at 400-600 MPa and a temperature of 1100-1200 C. EFFECT: higher efficiency. 2 cl, 1 tbl
