1. The addition of small amounts of boron (0.002%) and its distribution in the boundaries of zones and its interaction with carbon make it possible to obtain a substructure of martensite that is finer and more even in size after quenching of highly d

1. Diffusion aluminizing sharply increases (300\2-600%) the thermal stability of heating equipment and machine parts of carbon steels, particularly rolled sections. 2. Our results failed to confirm the reported effectiveness of substituting aluminize

Small additions of boron (0.002%) substantially increase the fracture toughness and change the fine structure of the steel investigated. The block size decreases and the dislocation density in subboundaries increases, which changes the overall charac

1. When alloyed with ∼0.003% B, steel 40GR with a section as large as 40 mm has a higher fracture toughness and lower cold brittleness threshold than steel 40G after quenching and tempering to a hardness of HB 290. 2. After quenching and low-temper

Normalization of low-alloy steel of type 10G2S1 in the range of Ac1-Ac3 leads to the formation of nonequilibrium structures, with an increase of the cold brittleness threshold as compared with standard normalizaiton.

1. The use of 36RL, 40GR, and 45R steels containing chromium in place of the carbon alloys and 45G2 and 40G steels makes it possible to improve the technological and working properties of machine parts made of these steels. 2. The use of 40GR steel f
