The effect of thermal action at 1100 °C on the kinetics of phase transformations in the coating obtained after aluminizing of 12Kh18N10T steel by immersion in a melt is studied. It was shown that after 500 hours of exposure, the chemical composition is leveled over the entire volume of the sample. Moreover, the predicted retention time of the heat-resistant properties of the coating at 1100 ° C is about 2000 hours.

The microstructure and mechanical properties of Ti joints brazed with a Zr41.2Ti13.8Ni10.0Cu12.5Be22.5 (at.%) amorphous filler were investigated. With a Zr-based amorphous filler, in this study, Ti joints with a homogeneous composition could be obtained by heating to well below the α-β transformation temperature for a short time, so that the undesirable effects of the high temperature heating are considerably diminished. The joints brazed at 790 °C for 10 min consisted of the coarse acicular structure rather than the fine Widmanstätten structure which generally deteriorates the ductility of the joints. The joints with the homogenous coarse acicular structure, i.e. without a residual liquid region, show almost the same mechanical properties as those required for base metals without heating. Although the residual liquid region in the joints deteriorates the ductility of the joints, this region could be successfully removed by a diminution in the quantity of the filler.

The effect of thermal action at 1100 °C on the kinetics of phase transformations in the coating, obtained by hot-dip aluminizing of 12Cr18Ni10Ti steel, is studied. It was shown that, after 500 h of exposure, the chemical composition is leveled over the entire volume of the sample. Moreover, the predicted retention time of the heat-resistant properties of the coating at 1100 °C is about 2000 h.
