Structure and properties of powder-metallurgical materials of the Fe-Cr-Cu-C system

Autor: N. A. Nikishov, I. V. Bogolyubova, S. Yu. Lopukhin

Publikováno v: Metal Science and Heat Treatment. 34:700-703

1. In powder-metallurgical, composites of the Fe-Cr-Cu-C system, upon varying the chromium content and the sintering temperature bright regions are formed based on the starting chromium containing special chromium carbides. Upon increasing the chromi

Influence of heating rate on the alpha?gamma-transformation critical temperatures in 40Kh steel

Autor: V. G. Ul'yanov, N. A. Nikishov, A. M. Sokolov

Publikováno v: Metal Science and Heat Treatment. 33:561-564

1. In heating at rates of vh≅0.7–36 deg/sec 40Kh steel with an original ferritic-pearlitic structure has higher critical α→γ-transformation temperatures than with a martensitic structure. 2. With heating rates up to ∼3 deg/sec the critical

Effect of methods of heating during sintering on the properties of iron-base powder materials

Autor: N. A. Nikishov, I. V. Bogolyubova, N. V. Nikitina

Publikováno v: Metal Science and Heat Treatment. 33:61-64

1. The use of induction instead of furnace heating during the sintering of powder materials of different compositions leads to the formation of a structure with no, or only a small quantity of, excess carbide phase. 2. Induction heating improves the
