TO IMPROVE THE STRENGTH CHARACTERISTICS OF BUILDINGS CUTTERS CUTTERS USING THE METHOD OF EQUAL CHANNEL ANGULAR PRESSING
Influence of grain size on the mechanical and performance properties of metallic materials is analyzed. Methods for grain refining - equal channel angular extrusion (ECAE) is re- viewed in the article. The method of equal channel angular pressing is described. Influence of ECAE on mechanical properties is investigated. The experiment of ECAE and conclusions about influence of compression on mechanical properties of metals are made.
