Technical field

The present invention relates to rare-earth alloy material technical fields more particularly to a kind of rare-earth alloy material and preparation method thereof.

Background technique

Rare earth has the laudatory title of " industrial vitamin ", nowadays has become extremely important strategic resource.Rare earth material is wide General applies in fields such as oil, chemical industry, metallurgy, weaving, ceramics, glass, permanent-magnet materials, with advances in technology and application technology Continuous breakthrough, the value of rare earth oxide will be increasing.Rare-earth alloy material is in production, in order to guarantee the intensity of product And mechanical property, Zn, Mg element is often added, forms multielement enhanced phase.But the addition of Zn, Mg element, rare earth alloy can be made The crack-resistance sensitivity and anticorrosion stress-resistant reduced performance of material, are unfavorable for the raising of product quality.Based on this, how one is designed The all more excellent rare-earth alloy material and preparation method thereof of kind properties is the technical problems to be solved by the invention.

Summary of the invention

In view of the deficiencies of the prior art, the present invention provides a kind of rare-earth alloy materials and preparation method thereof.

The present invention is realized by following technological means solves above-mentioned technical problem:

A kind of rare-earth alloy material, each component including following mass percent: Zn4-6wt%, Sn0.4-0.6wt%, Y0.5-0.7wt%, Si1-3wt%, Mg2-4wt%, Mn1-3wt%, Fe24-28wt%, Co5-7wt%, Ni20-26wt%, Remaining is Cr；

A kind of preparation method of rare-earth alloy material, comprising the following steps:

(1) high temperature furnace, refining is added in Zn, Sn, Y, Si, Mg, Mn, Fe, Co, Ni, Cr；

(2) cooling is carried out to obtain the final product to raw material after refining.

Preferably, the preparation method of a kind of rare-earth alloy material, refining temperature is 1550-1840 in step (1) ℃。

Preferably, the preparation method of a kind of rare-earth alloy material, the cooling means in step (2) are as follows: using high Pressure water cools down to raw material after refining as coolant.

The present invention has the advantages that rare-earth alloy material of the invention adds Zn, Mg element, it is easy to form multielement enhanced Phase effectively improves rare-earth alloy material tensile strength and comprehensive mechanical property；Using Cr as essential element, Zn, Mg element are made up Addition cause the defect of rare-earth alloy material crack-resistance sensitivity and anticorrosion stress-resistant performance；The addition of Mn element, on the one hand Hardening constituent can be formed with Zn, Mg element, the welding performance of rare-earth alloy material on the other hand can be improved；Each element cooperation, makes The rare-earth alloy material excellent combination property that must be produced, has a wide range of application.
