The tensile strain-hardening behavior of pure Ti at 100 K was investigated using X-ray diffraction line-profile analysis and plasticity simulation. The strain hardening was significantly increased at 100 K, compared with that observed at 298 K. Thus,

In order to ensure the integrity of structures such as gas turbines and nuclear power plants, the materials used should have excellent toughness. Especially in the case of nuclear piping materials applied to leak before break (LBB) design, high tough

The yield strength of commercially pure (CP) Ti of ASTM grade 4, the strongest among all the CP-Ti grades, is too low for structural applications that require high-strength materials. Here, we demonstrate the strengthening of grade-4 CP Ti by cryogen

We controlled the twin structure in pure Ti by deforming it at cryogenic temperature (∼77 K). Numerous thin individual twins were formed in the grains, thereby enabling strong twinning-induced grain refinement. The processed material had an ultrafi

Neutron diffraction peak profile analysis was used to determine stacking fault energy (SFE), dislocation density, and twin fault probability (Ptw) in CrCoNi and CrCoNiFe medium entropy alloys at 293K and 140K. The CrCoNi shows higher Ptw (up to 3.8%)

High Mn TWIP steel is regarded as a promising material for the next generation automobile steel because of its high strength and good ductility. Most of the rolling and recrystallization texture studies of TWIP steels have been made at relatively low

The effects of aging temperature on the microstructural evolution and the tensile behavior of precipitation hardened martensitic steel were investigated. Microscopic analysis using transmission electron microscope (TEM) was combined with the microstr
