Abstract

The difference in the carbon concentration in a weld and in a base metal causes the divergence of crystal lattice parameters and generates stresses on the boundaries between the weld and the base metal. It has been shown, on the example of carbon steels, which are solid solutions with the structure of -Fe type, that it is possible to regulate the lattice parameter of the weld. This regulation has been performed by using the admixture of Al, Mn, and Ti metals that are supplied with a powder welding wire. The formula for the zero increment of the lattice parameter with respect to that of the α-Fe lattice of the solid solution, is proposed δa = 0.01763ai+ 0.01763ti+ 0.00494mn+ 0.00188Cc– 0.00619si– 0.00849Cp= 0.
