Influence of Aging Conditions on Fatigue Fracture Behaviour of 6063 Aluminum Alloy

Sultan Qaboos University Journal for Science, 2001
Aluminum - Magnesium - Silicon (Al-Mg-Si) 6063 alloy was heat-treated using under aged, peak aged and overage temperatures. The numbers of cycles required to cause the fatigue fracture, at constant stress, was considered as criteria for the fatigue ...
