Abstract
Aluminium base alloys containing 0.1-15% Mg are heated to 400-750 DEG F. but below the critical oxidation temperature for 1-45 minutes in an atmosphere containing at least 75 m. grms. boron trifluoride per cubic foot. The boron trifluoride may be added as a vapour or by means of a solid which releases boron trifluoride at the furnace temperature, e.g. ammonium fluoborate or calcium fluoborate. The atmosphere may contain air, nitrogen, helium argon or fuel gas and may be contaminated with SO2, HCl, NH4, CO, or CO2 and water vapour in amount between 1/4 and 45 grains per cu. ft. may be present. The treated article may be degassed at a temperature above 750 DEG F. and may be age hardened. The alloy may contain 0.1-12% Cu, 0.25-14% Si, 0.1-20% Zn and 0.1-3% Mn and a maximum of 3% of the following "hardeners" may be present: 0.05-0.5% Cr, 0.01-0.5% Ti, 0.25-2.5% Ni, 0.01-0.5% B, 0.002-2.0% B and 0.1-0.5% of one or more of Mo, Zr, Ta, Nb, and Co. Specification 494,274 and U.S.A. Specification 2,379,467 are referred to.
