Abstract
Results of investigations of the processes of development of deformation of titanium interlayers with a plate-shaped microstructure, situated between the components of an alloy with a globular (equiaxed, fine-grain) structure, in diffusion welding conditions, are presented. It is shown that the reduction in relative thickness of a component with plate-shaped microstructure is accompanied by an increase in the creep rate of the microstructure, referred to as softening. Equations were derived for evaluating the coefficients of softening of the components with plate-shaped structures in dependence on their relative thickness and applied pressure.
