Abstract
- In the present research work, dissimilar metal joints of nickel-based superalloy (IN718) and low-alloy steel (EN24) round bars were carried out by using continuous drive friction welding. The joining of specimens was performed by varying friction time in the range of 2-10 s and keeping other welding parameters (friction pressure, 50 bar; upset pressure, 80 bar; upset time, 3 s; and rotational speed, 1400 rpm) constant. The main focus is to understand the characteristics of weld interface (WI), burn-off length and mechanical behavior of weld samples. It is noteworthy that significant changes in the microstructure caused variation in hardness across the weld interface. Moreover, it was observed that burn-off length increased linearly from 4.2 to 12.9% with increasing friction time. The tensile test results revealed that joint efficiency ~ 100% can be achievable by selecting the appropriate parameters. [ABSTRACT FROM AUTHOR]
