Investigation and Joint effect Analysis of Ti-6AL-4V & SS-304L in Aerospace Applications

Abstract

The friction welding basic principle is connecting two materials with the help of friction generated between them using pressure and frictional time. The material used for this is Ti-6AL-4V & SS-304L with aluminum interlayers. The mechanical and metallurgical experimental strengths are investigated successfully. Titanium and stainless steel joined materials are commonly used for different aerospace, chemical, automotive and nuclear applications. The primary investigation of this present work is the connection between titanium and stainless steel with an aluminum interlayer. Initially, stainless steel and aluminum joints were made, and then the aluminum other surface was connected with titanium alloy. Joined welded samples are analyzed with scanning electron microscopes. Welded joint strength and characteristics were determined with the help of the tensile test, micro hardness and impact test. These investigation results were studied and compared with previous experimental studies.

Microstructure and Mechanical Properties of Laser-Welded Joint of Tantalum and Stainless Steel

“…However, due to the scarcity of Ta resources on Earth, high energy consumption in smelting, and high application costs [5], Ta and other metal connection research is urgently needed. Many components for aircraft engines are made of stainless steel [6,7], which is resistant to corrosion and heat, and has high strength and toughness. Using appropriate Ta-steel composite structure parts and replacing local stainless steel materials with Ta can improve the high temperature resistance of components, extend the working life of aircraft engines, and have good economic benefits.…”
