This book presents one of the most complete compendiums of notch-tensile, tear, and fracture toughness data ever compiled. Information and data are included for a wide range of aluminum alloys, tempers, and products (sheet, plate, extrusions, forgings, and castings). Much never-before-published data is included. Typical and minimum plane-stress and plane-strain fracture toughness values are given for many of the high strength alloys for which such values have been generated. The effects of temperature are covered extensively, especially for the notch-tensile and tear data. Fracture data for welds, as well as the parent alloys and products are also included. This volume will be helpful for alloy selection and design, and particularly useful in assisting materials specialists and designers in judging the relative toughness of aluminum alloys, tempers, and products being considered for critical applications. All data was thoroughly reviewed by a select committee of the Aluminum Association Inc.
