EFFECT OF FRICTION TIME ON MICROSTRUCTURE AND MECHANICAL PROPERTIES OF FRICTION WELDED INCONEL718 AND SS410 DISSIMILAR JOINTS
Keywords:
Friction welding , Friction Time, Microstructure., Tensile strength, Hardness testAbstract
This paper illustrates the influence of friction time on microstructure and mechanical properties of the friction welded Inconel 718 and SS 410 dissimilar joints. The experiments were conducted by varying the friction time 6 sec to 10 sec at 1500 RPM rotational speed and 189 MPa of friction pressure. A total of five experiments were conducted and the corresponding tensile strength and Vickers micro hardness were recorded. A detailed macro and microstructural analysis were performed at the interface for all the joints and presented. It was found that the friction time plays major role on the mechanical properties of the joint and the ultimate tensile strength and hardness was found to be 679 MPa and 406 HV
