The grain size, dislocation density and the nature of their distribution in the matrix were determined by the EBSD method. It was found that effects of Ti on the structure and mechanical properties of cast ZG35 steel are complex, involving three adverse and one beneficial influence.

A single high-temperature tempering of the surfacing sample with the substrate was shown to increase the microhardness of the deposited layer to 5.96 GPa, which is approximately twice the hardness of the substrate (30KhGSA steel). Microhardness remains nearly uniform across the surfacing thickness. Double tempering led to a further increase in the microhardness of the surface layer (100 μm thick) to 7.1 GPa. In this case, microhardness gradually decreases with depth, approaching values observed after single tempering.
