AbstractAdding nickel to a magnesium alloy (AM60B) during melting produced two types of intermetallic particles in the alloy: manganese nickel aluminide (Al 60Mn 11Ni 4) and nickel aluminide (Al 0.42Ni 0.58). The addition of 0.5 wt.% of Ni by wire dissolution resulted in the formation of Al 60Mn 11Ni 4 particles that were normally fine and uniformly distributed in the cast ingot, promoting grain refinement and significant improvement of tensile properties. Al 0.42Ni 0.58 particles were formed when nickel was added in powder form, and the particles were prone to coarsening and segregation during the melting process.
