• 論文の詳細を見る

• The paper describes the development of failure maps. These are maps with hydrostatic tensile stress as one axis and fracture strain as one axis and temperatures as the other, showing the fields of dominance of a given micromechanism of fracture : cleavage, ductile fracture, intergranular fracture, and so on. Maps are presented for three structural steels, one high purity chromium stainless steel, one high strength aluminium alloy and one high strength titanium alloy. They give an overview of the micromechanisms by which a given material may fail, and help identify the one most likely to be dominant in a given experiment, or an engineering application. They should give guidance in selecting materials for low-temperature use and in selecting processing parameters in deformation processing of the materials.
