Fatigue Behaviour in Fine Grained Aluminium Alloys
The effects of alloy production method on microstructure and hence fatigue crack growth rate and fracture mechanism have been examined for a variety of fine-grained/high dispersoid Al-Li-Mg-Zr and Al-Li-Cu-Mg-Zr alloys. Microstructures have been assessed by scanning and transmission electron microcopy, together with electron back scattered diffraction pattern assessment. In these fine-grained/h...
متن کاملOn the mechanical behavior of single crystal NiTi shape memory alloys and related polycrystalline phenomenon
Room temperature monotonic and cyclic stress–strain curves for single crystal and polycrystalline NiTi shape memory alloys containing Ti3Ni4 precipitates are presented. The tensile and compressive single crystal results illustrate the importance of crystallographic texture, the unidirectional nature of the martensitic transformation, and martensite detwinning on tension-compression stress–strai...
متن کاملEffect of frozen spin on the magnetocaloric property of La0.7Ca0.3CoO3 polycrystalline and single crystal samples
Polycrystalline (PC) and single crystalline (SC) samples of La0.7Ca0.3CoO3 (LCCO) with the perovskite structure were synthesized by conventional solid-state reaction and the floating-zone growth method. We conducted isothermal magnetization measurements of the PC and SC samples at temperatures from 2.8 K to 140 K, and evaluated the magnetic entropy change (−ΔSM) under zero field cooling (ZFC) a...
متن کاملSegregation of boron to polycrystalline and single-crystal
Strong boron segregation to polycrystalline Si1 x yGexCy alloys from Si has previously been reported [MRS Symp. Proc. 669 (2001) J6.9]. In this study, we investigate potential mechanisms for this effect. We find that comparable segregation also occurs in both polycrystalline Si1 yCy and single-crystal Si1 x yGexCy, indicating neither Ge nor grain boundary effects are needed for it to occur. In ...
متن کاملUltrafast Dynamics of Single Crystal and Polycrystalline VO2
In recent decades, interest has rapidly developed in the group of materials known as strongly correlated electron systems. These systems exhibit numerous startling behaviors ranging from high temperature superconductivity to the topic of this thesis: metalinsulator transitions, specifically in the material vanadium dioxide (VO2). Unfortunately, due to wide variations within and between sampl...
