This study investigated the hydrogen embrittlement (HE) characteristics of advanced high-strength steels (AHSSs). Two different types of AHSSs with a tensile strength of 1.2 GPa were investigated. Slow strain rate tests (SSRTs) were performed under v

Aim We evaluated and compared the clinical and pathological differences between pregnant and non-pregnant women with adnexal torsion. Methods We retrospectively reviewed 239 women with adnexal torsion from January 2006 to December 2015 in a tertiary

Malakoplakia can be caused by incomplete digestion of Escherichia coli by lysosomes, leading to recurrent urinary tract infections and consequential mass-forming events that mimic tumors.By using ultrastructural findings, we aimed to specify the proc

The effect of nitrogen on the stacking fault energy (SFE) was quantitatively evaluated in Fe–15Mn–2Cr–0.6C–xN (wt.%) twinning-induced plasticity steels using X-ray and neutron diffraction and transmission electron microscopy (TEM). The SFE va

Three Fe–15Mn–0.6C–2Cr– x N (wt.%) twinning-induced plasticity (TWIP) steels with N concentrations of 0.02%, 0.09% and 0.21% were fabricated using a pressure-induction furnace. The variations in tensile properties and deformed microstructure

Tensile tests were used to investigate the effect of grain size on the strain-induced martensitic transformation start temperature in metastable austenitic steel with special attention to ultrafine grain size. The austenite grains were refined to sub

The microstructure, dimple structure, and mechanical properties of a cold-rolled Fe–18Mn–0.6C–1.5Al TWIP steel were investigated as a function of annealing temperature. The recrystallization started at 600 °C and finished at 700 °C for the ho
