| 摘要 |
The invention relates to a method for the heat treatment of cast parts produced from a light metal melt, especially an aluminium melt, whereby internal stresses of cast parts formed in a complex manner can be especially effectively eliminated, and said method can be implemented in an economical manner and in such a way that it is efficient in terms of bell production. The respective cast part is quenched following an annealing process or from the casting heat, cooled to a low temperature, and then suddenly heated to a high temperature by being immersed in a salt melt at a temperature above the boiling temperature of water at a normal pressure. |
