TL;DR: In this paper, the authors examined how the strain rate affects the room-temperature tensile behavior of hydrogen-charged 316L stainless steels and found that a softening phenomenon was observed in the hardening behavior of the H-charged and homogenized specimen at a strain rate of 2 � 10 � 3 /s.

TL;DR: In this article, the effect of texture variation on the delayed hydride cracking behavior in Zr-2.5%Nb plates, crack growth rate and KIH tests have been carried out at temperature ranges varying from 415 to 506 K after texture modification by rolling.

TL;DR: Differential scanning calorimetric tests were carried out in Alloy 600 from room temperature to 800°C on various specimens, in order to investigate the origin of the exothermic and endothermic reactions that occur during thermal analyses as mentioned in this paper.

TL;DR: In this paper, a delayed hydride cracking (DHC) testing at 250°C was conducted on two CB specimens with the notch directions tilted normal to, and at an angle of 60° to, the transverse direction of a cold-worked and annealed Zr-2.5%Nb pressure tube.

TL;DR: In this paper, the amount of strain-induced martensite (SIM) has been in situ measured at the center region of the gage section of the tensile specimens or ex situ measured on the fractured tensile samples.
