Effect of Nano-oxides on the Structure and Properties of Low-alloy Steel Weld Metal

The article presents the effect of nano-oxides on the distribution of non-metallic inclusions as well as on the weld metal structure during welding of low-alloy steels. It has been ascertained that providing the weld pool with a 0.5% vol. of aluminium and titanium nano-oxides leads to the formation of acicular ferrite structure characterised by high mechanical properties.
