On the correlation of mechanical and physical properties of 6061-T6 and 7249-T76 aluminum alloys

Al 6061-T6 was exposed to 75 heat treatments and Al 7249-76 was exposed to 90 heat treatments. The solution treatments, cooling rates and age hardening treatments were varied to simulate pitfalls that heat treaters may encounter. The physical and mechanical properties of thermally treated alloys were correlated and discussed.
