Abstract

The efficiency of using a vanadium barrier layer and a bimetallic composition composed of 08Kh18N10T stainless steel + VT1-0 titanium obtained by means of explosion welding in order to prevent occurrence of an intermetallic layer is studied in different temperature ranges. The evolution of the heat-affected zone in the samples subjected to heating to 600, 700, 800, and 900°C with exposure times of 1, 3, 5, and 10 h is studied with the use of scanning electron microscopy and metallography, and also the microhardness is measured. It is shown that the vanadium barrier layer reliably prevents mutual diffusion between steel and titanium at a high temperature, which excludes the formation of intermetallic compounds in the heat-affected zone. The efficiency of the barrier layer is evaluated.

不锈钢-钛双金属中高温钒阻挡层的效率

摘要

研究了在不同温度范围内使用钒阻隔层和由08Kh18N10T不锈钢+ VT1-0钛组成的双金属组合物的效率，该双金属组合物通过爆炸焊接获得，以防止金属间层的出现。使用扫描电子显微镜和金相学研究了加热至600、700、800和900°C，暴露时间分别为1,3、5和10 h的样品中热影响区的演变，并且还测量了显微硬度。结果表明，钒阻挡层可靠地防止了钢和钛在高温下的相互扩散，从而排除了在热影响区中金属间化合物的形成。评估阻挡层的效率。
