In this paper, the structure and mechanical properties of workpieces made Ti6Al4V alloy in shape blocks manufactured by wire-feed electron beam additive manufacturing processed friction stir processing were investigated. Samples cut from upper lower parts block layer deposition direction using different tool loading forces. Studies have shown that such material forms a clearly defined thermomec...

A variation of FSW, friction stir processing (FSP), has been used to modify selected regions of materials to enhance specific properties while eliminating fusion welding defects such as porosity, cracking, and the cast microstructure. The combination of fusion welding defects and high tensile residual stresses caused by the solidification of the molten weld pool adversely affect the post weld s...

Aluminium—boron carbide metal matrix composites (Al-B4C MMCs) belong to the class of materials extensively used in nuclear industry as a thermal neutron absorber spent fuel casks. This article investigates novel production method Al-B4C MMCs—Friction Stir Additive Processing (FSAP)—as an alternative casting or sintering. FSAP is derived from friction stir welding, which can be local modificatio...

Friction stir welding, a solid state innovative joining technique, is widely being used to join aluminium alloys for aerospace, marine automotive and many other applications of commercial importance. FSW trials were carried out using a vertical machining centre (VMC) on AA6061 alloy. The main objective of the present work was to evaluate the weld processing parameter of friction stir weld (FSW)...
