摘要：

The purpose of this work is to establish the rules relating the structure and design strength of P/M steels impregnated with copper. The carbon content, measured by the coulometric method, was 0.39 ± 0.05%. The mechanical properties were determined in accordance with GOST 18227-85 and the fracture toughness on type 4 specimens in accordance with GOST 25506-85. The influence of specimen dimensions on fracture toughness (KIc) was investigated on steel containing 0.7% nickel, 4% chromium, and 0.5% molybdenum.
