304不锈钢与6061铝合金搅拌摩擦焊温度场数值模拟
Numerical simulation of temperature field in friction stir welding of 304 stainless steel and 6061 aluminum alloy
摘要
Abstract
The traditional fusion welding method cannot overcome the interface brittleness problem caused by aluminum-steel intermetallic compounds,resulting in poor weldability of the composite structure of stainless steel and aluminum alloy.Therefore,this paper employs numerical simulation methods to investigate the friction stir welding of stainless steel and aluminum alloy.The welding temperature field is of great significance influence on the microstructure and the macroscopic morphology.A heat source model and boundary conditions suitable for friction stir welding of dissimilar metals were established using commercial finite element software.The quantitative relationship between welding speeds and the temperature field of friction stir welding of 304 stainless steel and 6061 aluminum alloy was analyzed.The results show that the results of numerical simulation are basically consistent with the results of infrared thermal imaging experiments,indicating that the established heat source model has high calculation accuracy.By comparing the temperature distribution on both sides of 304 stainless steel and 6061 aluminum alloy,it shows that the peak temperature of the 304 stainless steel side is higher than the peak temperature of the 6061 aluminum side during friction stir welding.关键词
