| Popis: | This investigation was conducted to determine whether variations in the heat treatment of 220 alloy would improve its resistance to stress corrosion cracking, and to compare the stress corrosion resistance of other high strength cast alloys with that of the 220-T4 alloy. Specimens of the alloys were stressed at 75 percent of their yield strengths while being intermittently immersed in a sodium chloride-hydrogen peroxide solution. The period of exposure was usually 60 days unless earlier failure occurred. Variations of magnesium contents between 9.1 and 12.7 percent did not affect the low resistance of alloy 220-T4 to stress corrosion cracking. Slow quenching from the solution heat treating temperature slightly improved this resistance. A sensitizing treatment or prolonged natural aging rendered the alloy more susceptible to stress corrosion cracking. The resistance to stress corrosion cracking of alloys A356-T61 and 357-T6 was rather uniform and was considerably better than that of 220-T4. The re... |
