Microstructure development of molybdenum during rotary friction welding
Materials Characterization, 2019Abstract Rotary friction welding is a solid state welding process where the required heat for welding is generated by friction caused by the relative movement between a stationary part and its rotary counterpart. As the melting temperature is not reached, this welding technique does not produce typical welding defects known from fusion welding.

Study on the friction interface evolution during rotary friction welding of tube
Journal of Adhesion Science and Technology, 2019AbstractIn this study, evolution characteristics of the friction interface during rotary friction welding of tube were investigated. The friction interface that obtained at different welding stage were observed by confocal laser scanning microscopy. The results show that the friction interface transforms from sliding friction state to visco-plastic ...

A comparison between friction stir welding, linear friction welding and rotary friction welding
Advances in Manufacturing, 2016Three friction welding processes are compared for temperature, stresses and strains, as well as strain rates developed in the early phases of the processes, which are essential in their successful development. These are friction stir welding (FSW), linear friction welding (LFW) and rotary friction welding (RFW).

Characterization studies on weld strength of rotary friction welded austenitic stainless steel tubes
Materials Today: Proceedings, 2021Abstract Austenitic stainless steel (SS304) tubes of outer diameter 19 mm, 2 mm thickness are joined together by rotary friction welding (RFW). The characterization studies are done by varying heating load, upset load, heating time, upset time and keeping constant spindle speed of 1100 rpm.

Rotary friction welding of AlCoCrFeNi2.1 eutectic high entropy alloy
Journal of Alloys and Compounds, 2020Abstract AlCoCrFeNi2.1 eutectic high entropy alloy was rotary friction welded, and the evolution of microstructure and the mechanical properties of the resultant joints were investigated. Compared with the base material, the amount of eutectic cells in the heat-affected zone decreased slightly, while most grains were bended and elongated in thermal ...

Nonlinear Numerical Model of Friction Heating during Rotary Friction Welding
Journal of Friction and Wear, 2018A calculation procedure to determine the temperature field during rotary friction welding of metal is proposed. An axisymmetric nonlinear boundary value problem of heat conduction taking into account the frictional heating of two cylinders (specimens) of finite length is formulated. It is assumed that the materials of specimens are thermally sensitive,

Rotary friction welding of an Fe3Al based ODS alloy
Materials Science and Engineering: A, 2002Abstract An Fe 3 Al based oxide dispersion strengthened (ODS) alloy is under consideration for possible use as tubes in advanced heat exchangers, and it is necessary to investigate methods of joining the alloy to itself, and to Haynes 230 alloy. Previous experience on iron aluminides has shown them to be weldable by several processes, but it is known
