MATEC Web of conferences Vol. 243. P. 00019 (1-5)Abstract: Three-layer materials consisting of the V-4.9Ti-4.8Cr/ferrite steel 17Cr-12Ni-Fe /V-4.9Ti-4.8Cr
were obtained in the paper. Phase composition and microstructure of the transition zone of the three-layer
material of vanadium alloy V-4.9Ti-4.8Cr and ferrite steel 17Cr-12Ni-Fe were considered. The use of the
method of direct laser growing allowed obtaining a three-layer material with qualitative interconnection of
layers, as well as decreasing a multistage nature of deformation and thermal operations used when obtaining
a three-layer material in earlier works. Additional thermal treatment of a three-layer alloy led to growth of
matrix grains up to 100 m of the vanadium alloy. A uniform distribution of main elements V, Ti, Cr was
observed in the transition zone both before and after annealing. A zone of interdiffusion of the metals
amounted to 250-350 μm.
