热氢处理对两相及β钛合金加工组织和性能影响的研究

Study on the Effect of Hot Hydrogen Treatment on the Microstructure and Properties of Two Phase and β-Titanium Alloy Processing

摘要

钛合金具有优异的机械性能、耐腐蚀性及高温稳定性，在航空航天、医疗器械、化工装备、汽车制造等领域发挥着重要作用，其中双相钛和β钛合金由于其优异的综合性能受到人们的广泛关注。然而钛合金在制备过程中普遍存在晶粒粗大和微观结构不均匀的难题，严重限制了其性能发挥及应用范围的拓展。热氢处理是一种新兴的热处理技术，为解决上述难题提供了新思路，利用氢可逆合金化效应，热氢处理可显著细化钛合金晶粒，改善组织结构，提高其加工性能与服役性能，有广阔的应用前景。

Abstract

Titanium alloys have excellent mechanical properties, corrosion resistance, and high temperature stability, and play an important role in aerospace, medical equipment, chemical equipment, automotive manufacturing, and other fields. Among them, duplex titanium and beta titanium alloys have attracted widespread attention due to their excellent comprehensive properties. However, titanium alloys commonly suffer from problems such as coarse grain size and uneven microstructure during the preparation process, which severely limits their performance and application scope. Hot hydrogen treatment is an emerging heat treatment technology that provides new ideas for solving the above problems. By utilizing the reversible alloying effect of hydrogen, hot hydrogen treatment can significantly refine the grain size, improve the microstructure, and enhance the processing and service performance of titanium alloys, with broad application prospects.
