Abstract
FIELD: powder metallurgy. SUBSTANCE: billets are produced from initial material like tungsten-copper or molybdenum-copper with copper share of 15 - 70 mas % and sintered in hydrogen medium under temperature of 1200 C. Sintered billets are rolled by rolling mills with total deformation of 20 -80 % . In the case ratio of working rollers diameter (D) and thickness of initial sintered billet (H) is determined as D/H = 12.8 A-96, with A - coefficient, corresponding to copper percentage of the billet. EFFECT: decrease of anisotropy of linear thermal coefficient of material expansion. 1 tbl
