Determination of the Critical Stress Associated with Dynamic Phase Transformation in Steels by Means of Free Energy Method [PDF]
The double differentiation method overestimates the critical stress associated with the initiation of dynamic transformation (DT) because significant amounts of the dynamic phase must be present in order for its effect on the work hardening rate to be ...

Predicting the Critical Stress for Initiation of Dynamic Recrystallization
The critical stress for initiation of dynamic recrystallization (DRX) can be identified from the inflection point on the strain hardening rate (qds/de) versus flow stress (s) curve. This kind of curve can be described by an equation that fits the experimental q-s data from zero to the peak stress.

In cold regions, the permanent settlement of embankment is mainly caused by the repeated freeze-thaw process and long-term repeated train loads. Meanwhile, the critical dynamic stress (σdcr) is an important parameter index for determining embankment ...

Determination of the impact of strain rate on dynamic recrystallization of hot-deformed 2205 duplex stainless steel [PDF]
2205 duplex stainless steel suffers poor hot workability, especially whe1981hot-deformed. This investigation aims to determine the strain rate’s effect on the material’s dynamic recrystallization after heat treatment.

Norwegian Police Use of Firearms: Critical Decision-Makingin Dynamic and Stressful Situations [PDF]
Abstract This is the first study of police decision-making regarding the use of firearms in the Norwegian context; its purpose is to study how police emergency response officers make decisions on the use of firearms, and to understand the contextual factors underlying these decisions.
