Thermal treatment of cast aluminum alloy

The purpose and type of cast aluminum alloy heat treatment
The mechanical properties of casting aluminum alloy often do not meet the requirements of use, and need to be further improved through heat treatment. The purpose of heat treatment is as follows:
%1 comprehensively improves the mechanical properties of castings, and improves the processedability of alloy. %1 Eliminate the internal stress caused by unevenness of the wall thickness and rapid cooling;
%1, the size and organization of stable castings to prevent and eliminate the edge volume caused by high temperature;
%1, eliminate bias and needle -shaped tissue, improve the micro -tissue and mechanical properties of alloy.
Casting quenching
Put the newly solidified aluminum castings in the water directly into the water to quench, so that the solid solution is saturated, and then the thermal treatment effect similar to T5 and T6 can be obtained, which is called casting quenching. It can save the process of repeatedly heating the cooling casting to the quenching temperature, shorten the production cycle, reduce power consumption, and save production costs. And have certain economic value.
2 Waiting for temperature quenching
Generally, the labor timing is quenching in the cooling medium after the high temperature I solid soluble, and then cooled to the room temperature before performing timely treatment. So -called
Waterless
When the temperature quenching, the alloy solid solution is treated directly to the medium of the artificial time temperature of the alloy, and the heat preservation to the artificial timeliness is completed.
