1. The alloys of the system Fe−Cr−Co containing 10–12% Co have better magnetic properties than all the known low-cobalt alloys of this calss. 2. Adding titanium to Fe−Cr−Co alloys with 12−10% Co ensures that a sufficient coercive force (4

1. As the titanium content of the alloy is increased, the range in which γ phase exists becomes narrower, the initial temperature of the high-temperature α→γ+α transformation drops, and the time required for the transformation increases. 2. The

1. The sintering of Ni-Fe alloys in the temperature range 1050–1200°C results in the formation of solid solutions of iron in nickel. Raising the temperature increases the degree of homogenization of the alloys, but is incapable of eliminating all

1. Cu-Al alloys made by powder methods show higher resistance to compression than do cast ones of the same composition in the range 20–300°C. 2. This increased resistance in Cu-Al cermets is associated with the oxides, very small grain size, and p

1. During the sintering of mixed copper and aluminum powders at temperatures above the eutectic point, the compacts exhibit growth, which depends on the particle size of the aluminum powder and the rate of heating during sintering. 2. The smaller the
