Abstract: Transverse V-notch Charpy specimens prepared from sheet bar of 1045, 4140, and 4340, each in four different metallurgical conditions, were deformed to fracture in slow bending at four diverse ...

Abstract: A general kinematically admissible velocity field applicable to forging of a rectangular strip of a incompressible material is presented. Generalized shape of any dead zone, if assumed, can be ...

Abstract: Rolling-direction tensile specimens of 0.31 C quenched and tempered alloy plate steel displayed cup-and-cone, split-layered, neck-and-split, and square-break fracture configurations over distinct ...

Abstract: A total of 31 stress-rupture data sets for 28 different nickel-base alloys, including 1153 individual test results, have been treated by graphical methods and computer programs to allow ...

Abstract: Demonstrated by results obtained with highly modified or original computer programs, accomplished with 31 data sets for C, Mo, and Cr-Mo steels, is the general superiority of the new Goldhoff-Sherby ...

Abstract: A type of tensile fracture topography encountered fairly often in certain temperature ranges with specimens from forgings, billets, rod, and bar of quenched and tempered steel, is the “star” ...

Abstract: Quenched and tempered plate steel is capable of modified cup-and-cone fractures involving one or more longitudinal cracks “parallel” to the flat plate surfaces. The occurrence was verified by ...

Abstract: V-notch Charpy bars were ruptured at seven deflection rates at test temperatures from the ambient through the blue-brittle range, while unnotched tensile specimens were equivalently tested at ...

Abstract: Available equipment initially developed for welding research studies was used to investigate the creep-rupture behavior of AISI type 347 stainless steel in a very-high-temperature range from 62 ...
