Abstract

The invention provides a high-hardness alloy forged piece and a preparation process thereof, and relates to the technical field of metal forged piece machining. The high-hardness alloy forged piece ismade of the following raw materials of, in percentage by weight, 10.2%-12.4% of Ti, 6.8%-8.2% of Ni, 5.3%-6.2% of C, 2.6%-3.8% of Si, 0.8%-1.4% of Tb, 4.6%-5.4% of Al, 1.2%-1.6% of V, 3.8%-6.4% of Fe, 1.6%-2.3% of Cr, 0.4%-0.8% of W, and the balance Cu. According to the high-hardness alloy forged piece and the preparation process thereof, the defects in the prior art are overcome, the strength ofthe forged piece is improved while the toughness of the forged piece is ensured by adopting a novel alloy formula matched with the steps of carrying out forging and quenching, carrying out subzero treatment and the like, the hardness of the forged piece is further enhanced, the application value of the forged piece is improved, and the economic benefit is enhanced.

Description

technical field [0001] The invention relates to the technical field of metal forging processing, in particular to a high-hardness alloy forging and a preparation process thereof. Background technique [0002] A forging is an object in which metal is pressured to form a required shape or a suitable compression force through plastic deformation. This force is typically achieved through the use of a hammer or pressure. The forging process creates a refined grain structure and improves the physical properties of the metal. [0003] Generally speaking, forgings have higher toughness, but compared with castings, their strength is lower than that of castings in the same formula. And because the rapid development of metal industrialization now has higher requirements for metal forgings, in addition to ensuring the necessary strength of its metal parts, it is also necessary to increase its hardness according to the application range, so how to improve the formula and preparation pr...
