Correlation of microstructure with tensile and crack tip opening displacement properties at low temperatures in API linepipe steels
The correlations of the microstructural factors with the tensile and crack tip opening displacement (CTOD) properties at −20 and −60 °C for three kinds of API linepipe steels were investigated. The C steel com...

Adiabatic shear banding and cracking phenomena occurring during cold-forging simulation tests of plain carbon steel wire rods by using a split Hopkinson’s pressure bar
Adiabatic shear banding and cracking phenomena occurring during cold forging of plain carbon steel wire rods, whose carbon content was varied from 0.2 to 0.8 wt%, were analyzed by forging simulation test using...

Dynamic compressive properties obtained from a split Hopkinson pressure bar test of Boryeong shale
Dynamic compressive properties of a Boryeong shale were evaluated by using a split Hopkinson pressure bar, and were compared with those of a Hwangdeung granite which is a typical hard rock. The results indicat...

Edge-Cracking Behavior of CoCrFeMnNi High-Entropy Alloy During Hot Rolling
This work investigated edge-cracking behavior of equiatomic CoCrFeMnNi high-entropy alloy during hot rolling at rolling temperatures 500 ≤ TR ≤ 1000 °C. Edge cracks did not form in the material rolled at 500 °C, ...

Effect of Microstructural Features on the High-Cycle Fatigue Behavior of CoCrFeMnNi High-Entropy Alloys Deformed at Room and Cryogenic Temperatures
In this study, we examined the effect of deformation twins and dislocation cell structures on the fatigue properties of the CoCrFeMnNi high-entropy alloy using rotational bending fatigue tests. The dislocation...
