Influence of Tungsten Carbide and Titanium Carbide Nanoparticles on the Structure and Properties of the Weld Metal
- 2 Downloads
The influence of nanoparticles introduced into a molten weld pool using a flux-cored wire on the structure and impact toughness of the weld metal is considered. The use of a flux-cored wire with tungsten carbide particles is shown to decrease the scatter of the impact toughnesses of the weld metal. The use of titanium carbide allows one to increase the average impact toughness.
