Diffusion Bonding and Post-Weld Heat Treatment of Extruded AZ91 Magnesium Alloys

Medžiagotyra, 2015
The grain size of as-extruded AZ91 magnesium alloys was refined to 12.31 μm from 21.41 μm by recrystallization annealing. The vacuum diffusion welding of as-annealed AZ91 magnesium alloys was researched. The results showed that the maximum shear strength
