摘要

The structure and properties of composite materials with a metal matrix based on titanium Grade 2 alloy and a pure copper powder are studied. It is found out that at the constant processing parameter values an excessive penetration of the tool into the workpiece surface is possible with the formation of beading or flash on the edges of the contact zone between the tool arms and the material. There is also stirring of the substrate material in the stir zone with the formation of a coarse dispersed macroscopically inhomogeneous structure. At high copper contents, the sample structure inhomogeneity increases, and in a number of experiments the formation of macroscopic defects is observed. After 1–4 passes of the tool there is an increase in the homogeneity of the powder particle distribution in the stir zone.
