Abstract: In the low-temperature range, the engineering yield strength of polycrystalline bcc metals can change by a factor of 10 or more with serious consequences appearing in the form of catastrophic ...

Abstract: In this study, a set of two parameters was used to describe the state of dynamic equilibrium for hardening and softening behavior in a variety of metallic materials, subjected to cyclic and ...

Abstract: The influence of temperature and strain rate on the upper yield point of ingot iron was studied. Torsion tests were conducted using strain rates of 12.5/sec, 0.25/sec, and 0.0001/sec over the ...

Abstract: Corrosion fatigue crack growth rates for SAE 4340 steel in distilled water environments were investigated utilizing fracture mechanics techniques. Crack growth rates, resulting from various forms ...

Abstract: Plastic deformation that accumulates with running time may constitute a mode of failure in some rolling element applications, particularly at elevated temperature. This phenomenon is studied in ...

Abstract: The yield behavior of niobium (columbium) has been studied under conditions of different states of stress, temperatures and strain rates, material compositions, and microstructures. Using data ...
