| Abstract | Shape Memory Alloys (SMAs) offer specific adaptability to complex shaped structural parts. In this study, twodissimilar shape memory alloys are welded by friction welding and put through mechanical testing to find the best results forthose alloys that are welded together. On finding the best match of the alloys, we can compare the results with the alloy's baseproperties. The shape memory alloy is welded with another shape memory alloy by solid-state welding that enhances themechanical properties like hardness, tensile strength, flexibility, and improves its properties additionally in heat resistance andvibration resistance cost-efficiently. Friction welding was done using different parameters, and tensile testing was conducted forall the welded specimens. Metallurgical study was conducted for the highest tensile strength welded joint to produce a legitimateweldment that is capable of enduring sustained heat and vibration from other metals and gives a sustainable bond between thealloys, so they can be used in a large number of applications reducing the cost, creating a shape memory alloy weldment withanother base alloy and to improve their characteristics without any loss of desired properties. |
