Abstract

1,178,966. Heat-treating aluminiummanganese alloy. ALCAN RESEARCH & DEVELOPMENT Ltd. May 11, 1967 [June 29, 1966], No.29293/66. Heading C7A. A cast ingot of an alloy containing in percentage by weight:- Mn 0À6-2 Si up to 0À6 Fe up to 0À7 Cu up to 0À2 Zn up to 0À1 other impurities up to 0À1 each Al balance. is given a homogenising treatment in the range 515‹ C. to 625‹ C. and is then subjected to a treatment at a temperature at least 50‹ C. below that of the homogenising treatment and within the range 400‹ to 550‹ C. to effect precipitation of a major part of the manganese. The ingot may be cooled to ambient temperature between the two stages, or may be cooled directly from the first to the second temperature, 3 ingots treated in this way are said to develop fine grain size on subsequent working.
