Plastic anisotropy and associated deformation mechanisms in nanotwinned metals
Anisotropic plastic deformation in columnar-grained copper in which preferentially oriented nanoscale twins are embedded is studied by experimental testing, crystal plasticity modeling and molecular dynamics simulations. The dominant deformation mechanism can be effectively switched among three dislocation modes, namely dislocation glide in between the twins, dislocation transfer across twin bo...
متن کاملDeformation and strength anisotropy of calcareous slates under Brazilian tests
Rock anisotropy plays an important role in engineering behavior of rocks. Slates are anisotropic rocks which have long been used for gable roof, floor tiles, borrow materials, and other purposes. The slates studied in this research are calcareous and have a porphyro-lepidoblastic texture. To determine the role of the anisotropy on the tensile strength and fracture pattern, two variables includi...
متن کاملReviewing the class of Al-rich Ti-Al alloys: modeling high temperature plastic anisotropy and asymmetry
In the last decades, the class of Ti-rich TiAl-based intermetallic materials has replaced many contemporary alloys till 900 °C. Due to higher oxidation resistance, 20% lower density and higher (about 150 °C more) operating temperature possibility of Al-rich TiAl alloys over Ti-rich side, phases from the Al-rich region of this alloy system are considered to be highly potential candidates for hig...
متن کاملRelationship between Af temperature and load changes in Ni-Ti orthodontic wire under different thermomechanical conditions.
Simple three point bending tests were performed on Ni-Ti wires with three different Af points (1 degree C, 13 degrees C and 34 degrees C) to clarify the relationship between Af temperature and load changes under constant deformation. Each wire was deformed at 37 degrees C and then thermal changes were imposed by temperatures of 2 degrees C or 60 degrees C. The load changes with thermal changes ...
متن کاملInfluence of Plastic Deformation on the Temperature Dependence of Ultrasonic Attenuation in Copper Single Crystals
The influence of plastic deformation (O<&<10%) on the MHz-ultrasonic attenuation a in single crystals of pure Cu, Cu50ppmAu and Cul30ppmAu has been measured over the temperature range 4<T<300K. The major contributions to the total attenuation originate from dislocation resonance, double-kink relaxation, phonon-electron interaction (at T<50K) and non-dislocation effects which are discussed espec...
