Rotary Friction welding is a process of solid state joining, broadly in shaft and pipe weld, in the field of automobile, defence, aeronautical, chemical and nuclear environment assembly pipe lines. Due to its some distinctive advantages similar to ease of fabricate, environmentally sociable, high fabrication value and appropriate for similar, dissimilar metal joint. Now a day’s Titanium alloy and stainless steel materials are very popular material in industrial application due to its high mechanical potency, and non-corrosive in nature. In this study an attempt was made to join commercial rod of Ti-6Al-4V and Stainless steel304L with some methods and evaluates the joint strength. Different intermediate metals are taking on in this process and the outcomes are witnesses. From that study the best method of in-between metal was analyzed by carry out mechanical and metallurgical test.

Bending Behavior

In this research, high-density polyethylene rods were joined together using rotary friction-welding. The effects of nanoparticle reinforcement and weld surface shape on the welded joint strength were investigated. To this aim, high-density polyethylene rods with a length of 50 mm and a diameter of 22 mm were machined, and three weld surface shapes, that is, flat, step, and conic shapes (on male and female counterparts), were created. The high-density polyethylene rods were rotary friction-welded with the addition of ZnO and SiO2 nanoparticles. The bending strength of rotary friction-welded rods was assessed by conduction of three-point bending tests. The results showed that both the weld surface shape and nanoparticles influence the bending strength of the welded joints. It was found that the step sample welds have higher bending strength (average bending depth and force of 6.27 mm and 2027.8 N, respectively). Furthermore, except for the case of flat samples, the addition of the reinforcement nanoparticles resulted in the improvement of the bending strength of the rotary friction-welded rods.

In the present study, the microstructure and strength properties of diffusion bonded joints of duplex stainless steel (SS) to Ti alloy (TiA) with and without nickel alloy (NiA) as an intermediate material was investigated in the temperature range of 800-950°C for 60 mins in vacuum. In the case of directly bonded stainless steel and titanium alloy, the layer wise σ phase and λ+FeTi phase mixture were observed at the bond interface. However, when nickel alloy was used as an interlayer, the interfaces indicate that Ni3Ti, NiTi and NiTi2 are formed at the nickel alloy-titanium alloy interface and the stainless steel-nickel alloy interface is free from intermetallics up to 875°C and above this temperature, Fe-Ti and Fe-Cr-Ti base intermetallics were formed. The irregular shaped particles have been observed within the Ni3Ti intermetallic layer. The joint tensile and shear strength were measured; a maximum tensile strength of ~519.2MPa and shear strength of ~398.3MPa were obtained for direct bonded joint when processed at 875°C. However, when nickel base alloy was used as an interlayer in the same materials at the bonding temperature of 900°C the bond tensile and shear strength increases to ~596.5MPa and ~434.4MPa, respectively.
