| 11 | Sintering Mechanism of Stainless Steel in Powder Injection Molding显示文摘Stainless steel samples were made by Powder injection Molding (PIM) process with-400 mesh powder in order to investigate the sintering mechanism in this system and develop the PIM of stainless steels. The process included mixing, injection molding, debin- ding and sintering. Neck growth model was used to analyze the sintering mechanism. The results show that lattice (volume) diffusion is the main mechanism in the sintering process, the products with higher density (>95%) and properties are obtained. At lower temperatures, grain boundary diffusion may play a role in the sintering densification. | Chengchang Jia Shimin Fan Ying Peng Xiaojie Zhao Xiaosen lu Material Science and Engineering School, University of Science and Technology Beijing, Beijing 100083, China Beijing Tungsten and Molybdenum Factory, Beijing 102206, China Beijing Hard Me | 2000 | International Journal of Minerals,Metallurgy and Materials2000，14，1： | 0 |
