Abstract

The invention discloses an alloy material for power mechanical parts and a preparation method thereof. The alloy material comprises the components of titanium boride, aluminum, iron, manganese, nickel, lanthanum or cerium, tin, zinc, silicon, phosphorus and copper, wherein the weight percentages of the components of the alloy material are as follows: 3-4.5% of titanium boride, 17-19% of aluminum,10-11.5% of iron, 3-4.5% of manganese, 4-5.5% of nickel, 2-3.5% of lanthanum or cerium, 1-2.5% of tin, 1-3.5% of zinc, 0.5-1.5% of silicon, 0.5-1% of phosphorus, and the balance of copper. Titanium boride ceramic particles are added in traditional bronze materials for improving the hardness of casting alloy materials; and corresponding rare earth elements of lanthanum or cerium are properly addedfor further refining and improving the particle size structures of alloy internal materials, so that the strength and the hardness off the alloy materials can further meet the requirements of materials for nuclear power steam turbine wear resisting pump blocks under the precondition of no need of further forging or heat treatment of the materials.

Description

technical field [0001] The invention relates to the field of alloy materials, in particular to an alloy material for power machinery parts and a preparation method thereof Background technique [0002] Bronze material has good properties such as ductility and forgeability, so it is widely used. It is mainly used in the technical field of nuclear power steam turbines, specifically for forging various valve blocks and wear-resistant pump blocks. However, with the vigorous development of the nuclear power industry, the market demands more and better materials. Due to the defects caused by forging, the bronze ingots currently used are increasingly unable to meet the domestic and foreign high-standard pump and valve alloy ingots. demand. In addition, due to the internal structure of the material, the bronze material cast by sand casting is very easy to produce air hole surface inclusions, and it is not easy to secondary molding.
