alsi42 alloy | solution treatment
The purpose of the solution treatment of Al-Si alloy is to fully dissolve Mg and Si into the α-Al matrix, which provides preparation conditions for the precipitation of more strengthening phases during subsequent aging; in addition, the morphology of the eutectic silicon phase changes from fibrous to granular transformation to improve the mechanical properties of the alloy.
alsi42 alloy | Effect of heat treatment on the microstructure and properties of cast aluminum-silicon alloys
The heat treatment of cast Al-Si alloy mainly includes solution treatment and aging treatment. Heat treatment will not change the external shape and overall chemical composition of the material, but adjust the internal structure of the material, thereby improving the performance of the material. The effect of heat treatment on α-Al lies in the solid solution of alloying elements in α-Al matrix and the precipitation of strengthening phase.
alsi42 alloy | Applications
alsi42 alloy aluminum-silicon alloy can be used in automobile engines to replace cast iron cylinders and significantly reduce weight. The aluminum-silicon alloy used as a cylinder can be electrochemically treated to etch the surface aluminum and then remain embedded in the basic primary silicon dots on the inner wall of the cylinder, and its scratch resistance and wear resistance are significantly improved. Its silicon content of 11% to 13% alloy has become one of the best piston materials due to its light weight, low expansion coefficient and high corrosion resistance.
