Science of materials

116-128 1931
Abstract

Data of thermodynamic modeling of balanced structure of powders of the mechanically alloyed thermo-reactive compositions, dependences of powders heating and structure of coverings on temperature of plasma stream, and also the results of optimization of spatter process are given.

129-133 1995
Abstract

Studied characteristics of structure formation in plasma balls anchor coulters planters made from highstrength вч 50.

134-138 480
Abstract

The comparative researches of microstructure of highstrength cast iron after laser and plasma processing are carried out. It is shown that the peculiarity of plasma processing is formation of deeper layers with hardness 950010000 MPa. At laser processing the depth of the strengthened layers is less (about 0,5-0,8 mm), and their hardness is higher (to 11000 MPa).

139-145 498
