摘要

An investigation of the influence of the structural state conditioned by different types of deformation-heat treatment (rolling and deformation on Bridgtnan anvils and following annealing) on wear under conditions of dry friction of bronze on steel was carried out. It was established that after casting, an alloy with a heterogeneous, dendrite structure was most susceptible to wear. A considerable decrease of wear was seen in materials with ultrafine-grained and subfine-grained structural states with equiaxial grains (0.2 to 0.3 mum).
