The creation of powder composite materials with high functional properties, such as maraging steel powders resistant to brittle degradation at negative temperatures, is one of the primary trends of modern material science. These steels are well machined by cutting, easily deformed and subject to heat treatment. The processes of sintering, hot extrusion, heat treatment, and structuring of porous compacts pressed from the maraging PS-H18K10M5Re steel powder obtained by synthesizing complex oxides have been studied. As a result of the research, a technology has been developed for obtaining products from maraging steel powder, including the processes of pressing porous steel powder, sintering compacts, hot extrusion and heat treatment. It is shown that the resulting powder steels are not inferior to the standard ones in terms of their physical, mechanical and technological properties, and in some cases even surpass them. |
