摘要

钛合金是一种重要的金属材料，具有优异的比强度，广泛应用于航空航天、核工业、化学医药、军工等领域。为了研究TC4钛合金与316L不锈钢在不同温度下的连接情况，在真空条件下对Ti57Zr13Cu21Ni9钎料进行了钎焊试验。采用扫描电镜(SEM)、能谱仪(EDS)和x射线衍射仪(XRD)对接头的微观结构、形貌和物相进行了表征。对接头的室温显微硬度和抗剪强度以及TC4与316L的结合机理进行了研究。结果表明:扩散层的主要相为Ti基固溶体和Ti- fe (TiFe和TiFe2)金属间化合物(IMCs)，钎焊中心主要由Ti- fe IMCs、(Ti, Zr)2(Ni, Cu)、Ti基固溶体组成。随着钎焊温度的升高，平均抗剪强度先升高后降低，在960℃时达到最大值133.9 MPa。

Effect of brazing temperatures on microstructure and properties of TC4/Ti57Zr13Cu21Ni9/316L

Titanium alloy is an important metal material with excellent specific strength, which is widely used in aerospace field, nuclear industry, chemical medicine, and military industry. In order to investigate the connection conditions of TC4 titanium alloy and 316L stainless steel at different temperatures, the braze welding measurement with Ti57Zr13Cu21Ni9 filler metal was conducted in vacuum. The microstructure, morphology and phase of the joint were characterized by SEM (scanning electron microscope), EDS (Energy Dispersive Spectrometer) and XRD (X-ray diffraction), respectively. Microhardness and shear strength of the joint at room temperature and the bonding mechanism of TC4 and 316L were also investigated. The obtained results revealed that the main phases in the diffusion layer were Ti-based solid solution and Ti-Fe (TiFe and TiFe2) intermetallic compoundsands (IMCs) the center of the braze was mainly composed of Ti-Fe IMCs, (Ti, Zr)2(Ni, Cu), Ti-based solid solution. Additionally, the increase of brazing temperature firstly increased and then decreased the average shear strength with the maximum value of 133.9 MPa at 960 °C.

期刊介绍： Metallurgical Research and Technology (MRT) is a peer-reviewed bi-monthly journal publishing original high-quality research papers in areas ranging from process metallurgy to metal product properties and applications of ferrous and non-ferrous metals and alloys, including light-metals. It covers also the materials involved in the metal processing as ores, refractories and slags. The journal is listed in the citation index Web of Science and has an Impact Factor. It is highly concerned by the technological innovation as a support of the metallurgical industry at a time when it has to tackle severe challenges like energy, raw materials, sustainability, environment... Strengthening and enhancing the dialogue between science and industry is at the heart of the scope of MRT. This is why it welcomes manuscripts focusing on industrial practice, as well as basic metallurgical knowledge or review articles.
