20090038720 | Heat Treatment of Aluminium Alloy High Pressure Die Castings - A method for the heat treatment of a casting produced by high pressure die casting, that may exhibit blister forming porosity in the as-cast condition, of an age-hardenable aluminium alloy, includes solution treating the casting by heating the casting to and within a temperature range enabling solute elements to be taken into solid solution. The casting then is cooled to terminate the solution treatment by quenching the casting to a temperature below 100° C. The cooled casting is held in a temperature range enabling natural and/or artificial ageing. The solution treatment is conducted to achieve a level of solute element solution enabling age-hardening without expansion of pores in the casting causing unacceptable blistering of the casting. | 02-12-2009 |
