摘要：
A sintered material for use in an internal combustion engine, such as a valve seat insert, is provided. The material includes a pressed base powder metal mixture and a Cu-rich phase infiltrated in pores of the base powder metal mixture. The base powder metal mixture includes at least one of Mo and W, and at least one additive, such as B, N, and/or C. The amount of the Mo and/or W is 50 wt. % to 85 wt. %, based on the total weight of the material. The at least one additive is present in a total amount of 0.2 to 25 wt. %, based on the total weight of the material, and the Cu-rich phase is present in an amount of 15 wt. % to 50 wt. %, based on the total weight of the material. The material also has a thermal conductivity of at least 70 W/mK.
