HEAT TREATMENT OF ALUMINIUM ALLOY HIGH PRESSURE DIE CASTINGS. |
摘要 |
<p>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 degree 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.</p> |
