Nanoscale Modification of Weld Metal Microstructure
The are considered possibilities of influencing the a circular ferrite controlling content on welds metal mechanical properties. The method of adding titanium carbides to the welding bath liquid metal is considered. It is established that non-metallic inclusions with a size of 0.3 μm to 0.8 μm and titanium carbides on surface determine the conditions for the microstructure formation and the level of weld metal mechanical properties.
