FIELD: process engineering. ^ SUBSTANCE: invention relates to composite tool materials and may be used and may be used for production of various-purpose tools with higher mechanical properties. Proposed material consists of metal and composite components at preset relationship between ceramic component particle mean size and that of metal component, and specified particle size of ceramic component. Ceramic component particle mean size relates to that of metal component as 1:3-1:5 at mean particle size of ceramic component varying from 1 to 3 mcm, and amount of components, in wt %: ceramic component - 20-50, metal component making the rest. ^ EFFECT: higher mechanical properties of proposed material. ^ 2 cl, 1 tbl, 1 ex |
