摘要：
Effect of additives of 0.2-4.0% ultrafine nickel and 0.2-0.6% carbon on the sintering and physical and mechanical properties of stainless steel 17Cr-2Ni (Kh17N2) is studied. It is shown that complex addition with 0.5% Ni and 0.3% C obtained from the mixture of nickel oxalate and graphite powders after heating in hydrogen activates the process of sintering and increases density, hardness and toughness of the steel.
