|Title:||Deformation behaviour and microstructure evolution of AlMg6Mn alloy during shear spinning|
|Authors:||Radovic, Ljubica |
|Abstract:||Deformation behavior and microstructure of AlMg6Mn alloy subjected to shear spinning were studied by means of mechanical characterization, optical and SEM+EDS microscopy. Specimens were shear spun on an industrial spinning machine using different mandrels, providing reductions of wall thickness of 30, 50 and 68. The grain structure developed during shear spinning refines gradually. The grains elongate in axial direction with increase of reduction, and also stretches along circumferencial direction. Optimal combination of strength and elongation is observed. This is attributed to grain refinement and dislocation reactions with particles and atoms of Mg and Mn in solid solution. © 2012 The Nonferrous Metals Society of China.|
