Evolution of the Structure and Phase Composition of Rapidly Solidified Al–Mg–Mn–Sc–Zr Alloys during Deformation in a Bridgman Anvil

摘要

Metallography and electron microscopy are used to study the formation of submicrocrystalline and nano-structured states in Al–Mg–Mn alloys with scandium and zirconium during shear at a high hydro- static pressure. The evolution of the structure and changes in the hardness of the alloys are discussed in relation to their composition and casting and heat treatment conditions.
