Abstract

The paper investigates the features of bimetal formation from commercially pure titanium alloy and aluminum alloy 5056 using lap friction stir welding. The structure of bimetal and quality of joint depending on the change of tool feed rate is studied. Tensile tests were carried out to determine mechanical properties. The structure of bimetals was studied by methods of light optical and scanning electron microscopy. The results showed that the quality of titanium-aluminum bimetal in general is inversely proportional to the feed rate of the tool.The paper investigates the features of bimetal formation from commercially pure titanium alloy and aluminum alloy 5056 using lap friction stir welding. The structure of bimetal and quality of joint depending on the change of tool feed rate is studied. Tensile tests were carried out to determine mechanical properties. The structure of bimetals was studied by methods of light optical and scanning electron microscopy. The results showed that the quality of titanium-aluminum bimetal in general is inversely proportional to the feed rate of the tool.

喂料速度对搅拌摩擦焊钛铝双金属质量的影响

本文研究了市售纯钛合金与5056铝合金搭接搅拌摩擦焊双金属成形的特点。研究了刀具进给速度变化对双金属接头结构和接头质量的影响。进行了拉伸试验以确定机械性能。用光电子显微镜和扫描电子显微镜研究了双金属的结构。结果表明:钛铝双金属的质量一般与刀具进给速度成反比。本文研究了市售纯钛合金与5056铝合金搭接搅拌摩擦焊双金属成形的特点。研究了刀具进给速度变化对双金属接头结构和接头质量的影响。进行了拉伸试验以确定机械性能。用光电子显微镜和扫描电子显微镜研究了双金属的结构。结果表明:钛铝双金属的质量一般与刀具进给速度成反比。
