Effect of Additional Element on Weld Solidification Crack Susceptibility of Al-Zn-Mg Alloy (Report III) : Enhancement of Beneficial Effect of Zirconium on Improvement of crack susceptibility by Application of Electromagnetic Stirring(Materials, Metallurgy & Weldability)
Search this Article
It appeared that electromagnetic stirring was very effective to improve the susceptibility of solidification cracking in weld metal of Al-2%Zn-3%Mg alloy with 0.24% zirconium. This beneficial effect of electromagnetic stirring was mainly due to the grain refinement of weld metal, but it was not seen for the alloys with less zirconium content than 0.24%.
