AI Technical Summary

Technical Problem

During the preparation of molybdenum-titanium alloys, molybdenum powder and titanium powder are prone to oxidation, which leads to surface oxides that hinder the diffusion of metal atoms and the bonding between particles, forming weak areas that are prone to cracking. In addition, the oxygen absorption of titanium forms a brittle phase, which affects product quality.

Method used

Molybdenum powder and titanium powder are ball-milled under inert gas protection, the moisture content of the mixture is controlled, and the mixture is pressurized and sintered in an inert gas environment. The sintering temperature is controlled at 1200-1600℃. After forming a dense alloy block, it is processed into products by forging, rolling or extrusion, and then annealed.

Benefits of technology

It effectively avoids oxidation of molybdenum powder and titanium powder, reduces the risk of cracking, improves the density and mechanical properties of the product, and ensures product quality.

Abstract

The invention relates to the technical field of molybdenum-titanium alloy materials, in particular to a preparation method and application of a molybdenum-titanium alloy material.The preparation method of the molybdenum-titanium alloy material comprises the following steps that 1, molybdenum powder and titanium powder are fully mixed under protection of inert gas through a ball mill; 2, the mixed powder is subjected to pressure forming, and a billet is formed; 3, heating and sintering the billet under the protection of inert gas; and 4, the sintered compact alloy block is machined into a product through forging, rolling or extruding. According to the prepared molybdenum-titanium alloy material, in the preparation process, after molybdenum powder and titanium powder are treated through deionized water, some impurities on the surfaces can be removed, after the molybdenum powder and the titanium powder are wrapped with water, oxygen is not prone to being accumulated on the surfaces, in the subsequent ball milling process, oxygen can be effectively prevented from being clamped between the molybdenum powder and the titanium powder, and the service life of the molybdenum-titanium alloy material is prolonged. And the molybdenum powder and the titanium powder are not prone to being oxidized, finally, the billet is not prone to cracking in the sintering process, and the product quality is guaranteed.
