Embodiment 1

[0034] A metal material comprises the following components by weight percentage:

[0035] C1.6%, B0.2%, Mn0.3%, Cr12%, Sn0.8%, Al0.7%, Ti0.1%, Bi0.4%, Ce1.0%, Cu0.2%,

[0036] The rest is Fe.

[0037] The preparation method of the metal material is as follows: according to the formula, each component is put into a melting furnace for heating and melting, after melting, pouring is performed at 1570-1600°C, and after cooling to 920-950°C, put it into an incubator and cool to room temperature , and finally tempered at 400 ° C ~ 430 ° C.

Embodiment 2

[0039] A metal material comprises the following components by weight percentage:

[0040] C2.6%, B0.8%, Mn1.2%, Cr23%, Sn2.3%, Al1.5%, Ti0.8%, Bi1.0%, Ce1.5%, Cu1.0%, the rest is Fe .

[0041] The preparation method of the metal material is the same as in Example 1.

Embodiment 3

[0043] C2.1%, B0.5%, Mn0.8%, Cr16%, Sn1.7%, Al1.0%, Ti0.6%, Bi0.5%, Ce1.3%, Cu0.7%, the rest is Fe .

[0044] The preparation method of the metal material is the same as in Example 1.

Abstract

The invention provides a metal material and a preparation method thereof. The metal material comprises the following components by weight percentage: C1.6-2.6%, B0.2-0.8%, Mn0.3-1.2%, Cr12- 23%, Sn0.8‑2.3%, Al0.7‑1.5%, Ti0.1‑0.8%, Bi0.4‑1.0%, Ce1.0‑1.5%, Cu0.2‑1.0%, and the rest is Fe. The metal material has excellent mechanical properties, wear resistance, corrosion resistance, cold resistance, heat resistance and fluidity, its hardness can reach HV670, its strength can reach 635MPa, and it has excellent toughness, plasticity, stiffness and resistance In addition, the metal material has a tight texture and good quality, and can be widely used in the field of metal materials.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a 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, B, 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 for furt...
