The level of disability, along with the indices of the infant mortality rate, morbidity rate, physical development and health demographic processes is a basic index of child health, reflecting the level of economic and social well-being of the countr

Formation of structural morphology in alloys of the Kh23K15T type is accomplished in two heat treatment stages: from ITMT to the final tempering stage at 550–500°C. Depending on the conditions for carrying out stepwise heat treatment at different

1. Alloying with molybdenum makes it possible to lower somewhat the quenching temperature to α solid solution of Fe-15% Co+(20–35)% Cr alloys, although the hot plastic deformation temperature must be raised due to the broader range in which the σ

1. In alloys based on Fe−33% Cr−12% Co−2% Cu alloyed with 1% Al (alloy 2) or 1.5% Nb (alloy 3) the temperature for quenching to α-solid solution is reduced from 1050 (alloy 1) to 1000 (alloy 2) or 950°C (alloy 3). The temperature for the star

1. To simplify the thermomagnetic treatment of alloys YuNDK38T8 and YuNDK40T8 it is necessary to separate the step of “nuclei formation” from the stage of decomposition. 2. Nuclei of α′ phase can be formed in alloys YuNDK38T8 and YuNDK40T8 wit

1. The magnetic properties of the Fe−17.5Co−Cr alloy are extremely sensitive to the temperature and time of isothermal treatment in magnetic field and also to the subsequent tempering temperature. 2. The magnetic properties of the Fe−17.5Co−C

We investigated the effect of the cooling rate from 900 to 600° and high-temperature magnetic tempering at 790–830° on the magnetic properties of YuNDK35T5 alloys.

The magnetic properties of some ternary alloys PrCoxCu(5−x) in the range 4.5 ≥ x ≥ 2 have been investigated. The remanence and coercive force of these alloys both directly after annealing at 1020 °C for 5 h and after tempering for 4 h at 390
