Abstrakt: The peculiarities of defect formation in composite materials based on Grade 2 titanium alloy formed by friction stir processing with an addition of pure copper powder particles are studied. The results show that a macroscopically inhomogeneous structure is formed in the samples, which depends both on the number of tool passes along the processing line and on the volume fraction of the powder material added into the stir zone. The main stir zone defects include beading (flash), penetration of substrate fragments, formation of discontinuities and cracks. The stir zone homogeneity can be improved by increasing the number of tool passes along the processing line. However, in the case where the volume fraction of the added powder is large, even a multi-pass mode might fail to achieve a homogeneous stir zone structure. [ABSTRACT FROM AUTHOR]
