Embodiment 1

[0025] A new type of metal material includes the following components by weight percentage:

[0026] C1.6%, Si0.2%, Sn12%, Sr0.8%, Al0.7%, Ti0.1%, Bi0.4%, and the rest is Fe.

[0027] The preparation method of the metal material is as follows: according to the formula amount, each component is put into a melting furnace for heating and melting, and after melting, pouring is performed at 1580-1590°C, cooled to 920-950°C, and then placed in an incubator to cool to room temperature , and finally tempered at 460-480°C.

Embodiment 2

[0029] A new type of metal material includes the following components by weight percentage:

[0030] C2.6%, Si0.8%, Sn23%, Sr2.3%, Al1.5%, Ti0.8%, Bi1.0%, and the rest is Fe.

Abstract

The invention provides a novel metal material and a preparing method thereof. The metal material comprises, by weight, 1.6-2.6% of C, 0.2-0.8% of Si, 12-23% of Sn, 0.8-2.3% of Sr, 0.7-1.5% of Al, 0.1-0.8% of Ti, 0.4-1.0% of Bi and the balance Fe. The metal material has the excellent mechanical property, wear resistance, corrosion resistance, cold resistance, heat resistance and liquidity, the rigidity of the metal material can reach HV690, the strength can reach 640MPa, the metal material has the excellent toughness, plasticity, rigidity and wear resistance, in addition, the texture of the metal material is compact, the quality is good, and the metal material can be widely applied to the field of metal materials.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a novel metal material and a preparation method thereof. Background technique [0002] Alloy metal materials are more widely used in the current metal materials, and the general metal materials are basically composed of C, Si, Fe and other elements. These metal materials can meet general industrial needs, but in some fields that require high performance of metal materials, conventional metal materials are far from meeting the needs. my country's rare earth resources are at the forefront of the world. Due to their unique properties, infiltration of rare earth elements into steel can improve the performance of steel. Therefore, the current research on rare earth elements in the metallurgical industry has begun to be more in-depth. However, rare earth elements are generally expensive, and their addition amount and combination with those components are still a target f...
