A thermomechanically treated aluminum alloy containing 4. 5% Cu, 0. 6% Mn, 0. 6% Mg and 0. 4% Si has been experimentally investigated with regard to its notch sensitivity. The thermomechanical treatment consisted of quenching and ageing with different periods of precipitation, and different degrees of a cold plastic deformation afterwards. Five series of smooth and notched specimens were tested on a standard tensile machine and fracture surfaces were studied by TEM replicas. The Notch-Yield Ratio (NYR) and the fracture appearance were used as a measure of the notch sensitivity. It was found that certain thermomechanical treatments cause notch sensitivity and brittle fracture of notched specimens, even in the case of the low value of sigma //0//,//2/// RHO ratio. Thermomechanical treatment consisting of 120 minutes precipitation and 30% or 40% deformation degree of cold rolling deformation can be recommended as the most suitable for structural application.
