... for aluminum alloy 2014-T6 and the hardness surpassed the minimum hardness required for aluminum alloy 2014-T6. An abrupt change in the direction of grain flow across the fracture plane indicated that the wall had buckled during forging. This evidence supported the conclusion that the wheel half failed...
