| Abstract: | A process to develop the valve seat inserts in JL462Q engine is studied. The material is an iron-based alloy without Cr. The results show that the microstructures and properties of the product are as good as those of the product made in Japan. The effects of Mo. Ni. Co. Cu etc. in the alloy are also discussed respectively. |
