A high strength, heat treatable aluminum alloy
A high strength aluminum alloy is suitable for ultra thick gauge wrought product. The alloy can have 6 to 8 wt % zinc, 1 to 2 wt % magnesium, and dispersoid forming elements such as Zr, Mn, Cr, Ti, and /or Sc with the balance made of aluminum and incidental elements and/or impurities. The alloy is suitable for many uses, including in moulds for injection-molded plastics.
We report the yield and D/H of water released by stepped heating of bulk Shergotty, Zagami, Chassigny, and the newest martian meteorite, ALH 84001. For comparison, we also report data from Nakhla using the same procedure since the heating steps in this study are slightly different than our previously reported nakhlite analyses.
