Hardening of Aluminum Alloys Due to Scandium Alloying

  • ALUMINUM ALLOYS
  • Published:
Metal Science and Heat Treatment Aims and scope

The mechanism of hardening of deformed semiproducts from aluminum alloys upon the introduction of scandium into the latter is discussed. The hardening is explained by the presence of secondary dispersed particles of type Al3 Sc and formation of a subgrain structure in the semiproducts. Growth in the strain in fabrication of the semiproducts is accompanied by noticeable intensification of the hardening effect of the scandium additive, which is associated with refinement of the grain structure.
