the prepared particles are placed in a furnace for vtd under residual pressure in furnace chamber of 5 u00d7 10 u2212 3 millimeters of mercury at temperature of 550 650 deg c and holding for 1 2 hours the particles are cooled to 200 deg c while maintaining the vacuum pressure in the furnace chamber and a final cooling is executed together with furnace when vacuum pumps are cut off during vtd dirt is removed from the surface of chip scrap deformation cold hardening formed during machining of the alloy and chip scrap crushing is cut off as a result chip scrap pressing effort is reduced by 20 30 at prescribed briquette density the temperature of degassing from 550 deg c to 650 deg c under holding for 1 2 hours provides greatest effect of gas dirt removing and chip scrap surface microhardness cold hardening lowering use of vtd temperature over 650 deg c and holding for over 2 hours is not economically sound because of considerable power inputs the pressing cold molding by means well known in the art of chip scrap particles results in briquettes preferably having relative density in the range of 0 6 0 75 as is known in art for powder metallurgy mechanical or hydraulic presses may be used for the pressing operation steel pressing molds with surface hardness 45 50 hrc without lubricants may be used for transportation of chips and pressed briquettes stainless steel containers may be used the cold molding is carried out at ambient temperature the cold molding is performed under a steadily applied force applied.
