Effect of quenching in new media on the properties and structure of aluminum alloys
- 32 Downloads
For quenching of alloys D16, V95, and AK4-1, a 0.3–1.0% PEO solution with molecular weight≥3·106 is optimal. The permissible thickness of the quenched part varies with the type of alloy and PEO concentration.
The distortion after quenching in 0.5% PEO solution is 4–5 times smaller than after quenching in water, while the mechanical properties and corrosion resistance of semifinished products of alloys D16, V95, and AK4-1 meet the technical specifications.
The extent of decomposition of the solid solution in alloy D16 quenched in PEO solutions can be determined by the acoustical method.
