Abstract

The invention relates to a structural alloy material and a preparation method thereof. The structural alloy material comprises the following components in percentage by weight: 0.6-0.8% of Mg, 0.3-0.4% of Rb, 0.1-0.2% of Hf, 0.2-0.3% of Pd, 0.5-0.8% of Co, 3.3-3.6% of Ni and the balance of Fe. The preparation method of the structural alloy material comprises the steps of material taking, vacuum melting, press forming and cooling. The obtained structural alloy material has very high hardness and impact resistance and can be used for structural parts of large scale equipment to increase the hardness and the impact resistance of the equipment.

Description

technical field [0001] The invention relates to an alloy material and a preparation method thereof, in particular to a structural alloy material and a preparation method thereof. Background technique [0002] Metal alloy materials with different properties and uses can be prepared by melting several different metal materials at high temperature. Alloy materials with different compositions have different uses. Alloy materials are very versatile and can be used in various metal devices. For metal equipment such as some large equipment, the metal material of the structural components of the equipment has a very important effect on the equipment. If the hardness of the metal material of the structural part is low, the operation stability of the equipment will be reduced during the application process, not only The hardness of the metal material and the impact resistance of the metal material are also very important, which largely determine the performance of the structural par...
