Nanoscale Modification of Weld Metal Microstructure

Abstract

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 m to 0 8 m and titanium carbides on surface determine the conditions for the microstructure formation and the level of weld metal mechanical properties
