Microstructural Evolution of X45CrNiW189 Valve Steel During Hot Deformation
The hot compression tests were carried on X45CrNiW189 valve steel (X45) in the temperature range of 1000– 1200 °C and the strain rate range of 0.004 – 0.5 s-1 in order to study the high temperature softening behavior of this steel. For the exact prediction of flow stress, the effective stress-effective strain curves were obtained from experiments under various conditions. On the basis of experi...
متن کاملOrientation and deformation of mineral crystals in tooth surfaces.
Tooth enamel is the hardest material in the human body, and it is mainly composed of hydroxyapatite (HAp)-like mineral particles. As HAp has a hexagonal crystal structure, X-ray diffraction methods can be used to analyze the crystal structure of HAp in teeth. Here, the X-ray diffraction method was applied to the surface of tooth enamel to measure the orientation and strain of the HAp crystals. ...
متن کاملPseudoelastic Deformation of CuAlMn Single Crystals
Martensitic transformation associated with a tensile deformation of CuAlMn single crystals in [loo] direction was studied using in-situ transmission electron microscopy. Stress/strain curves obtained during pseudoelastic deformation of microscopic samples were slightly different fiom bulk ones due to martensite formation in the stage of stress increase and a permanent deformation during the fir...
متن کاملPlastic deformation of CoO single crystals
2014 Constant strain rate compressions along 001 > have been performed on CoO single crystals (03B5 ~ 6 x 10-5 s-1). Yield stresses and work hardening rates have been measured between 77 K and 1 400 K; CoO is very strong when compared to similar compounds. Vickers indentations have been performed on { 100 }, { 110 } and { 111 } faces around the Néel temperature, i.e. between 0 °C and 40 °C...
متن کاملPlastic deformation of single nanometer-sized crystals.
We report in situ electron microscopy observations of the plastic deformation of individual nanometer-sized Au, Pt, W, and Mo crystals. Specifically designed graphitic cages that contract under electron irradiation are used as nanoscopic deformation cells. The correlation with atomistic simulations shows that the observed slow plastic deformation is due to dislocation activity. Our results also...
