摘要: Efforts to reduce fuel consumption have led renewed interest in the use of magnesium alloys for lightweighting transportation structures. Powder metallurgy offers a processing route target unique compositions, microstructures and high performance alloys. Recent advances production, qualification, characterisation gas atomised AZ91E, WE43 Elektron21 alloy powders are highlighted. The structure powder was investigated using TEM. Fulfilling potential these emerging applications involves establishing compatibility with viable consolidation processes such as cold spray, laser assisted deposition, forging extrusion. Preliminary results this endeavour reported.
