| Abstract: | The high nitrogen stainless steel prepared by pressure smelting was introduced. The development of high nitrogen stainless steel prepared by powder metallurgy technology was summarized, including the powder preparation of high nitrogen stainless steel (such as high-pressure gas atomization technology and mechanical alloying) and the forming and densification method of high nitrogen stainless steel powder (such as injection molding, hot isostatic pressing technology, hot extrusion, powder-sintering-free forging, and spark plasma sintering). The problems on the preparation of high nitrogen stainless steels by powder metallurgy were pointed out, and the future development trend was predicted. |
