Orientation Dependence of Fatigue Fracture Behavior in Pure Titanium Single Crystals

Cyclic deformation behavior of high-purity titanium single crystals: Part I. Orientation dependence of stress-strain response

Torsion Property and Cyclic Fatigue Fracture Behavior of Nickel-Titanium Endodontic Instruments

The torsion property and rotary fatigue fracture behavior of Smart K file and R reamer made of nickel titanium alloy have been studied by means of Shimadzu Autograph DDS-10T universal tester and man-made cyclic system with curved copper tubes as simulated root canal. The instrument surface and the cyclic fatigue fracture surface have been investigated by optical microscope and scanning electro...

Fatigue and Fracture Behavior of a Cold-Drawn Commercially Pure Aluminum Wire

Fatigue properties and cracking behavior of cold-drawn commercially pure aluminum wires (CPAWs) widely used as the overhead transmission conductors were investigated. It was found that the fracture surface of the CPAWs shows an obvious four-stage fracture characteristic, i.e., crack initiation, planar crack propagation, 45°-inclined crack propagation and final rapid fracture. The crack growth m...

Orientation dependence of the anomalous Hall resistivity in single crystals of Yb14MnSb11

The Hall resistivity, electrical resistivity, and magnetization of single crystals of the tetragonal ferromagnet Yb14MnSb11 are reported as a function of the direction of the current I and magnetic field H with respect to the principal crystallographic axes. With I along the unique c direction and H in the a-b plane, the anomalous Hall resistivity in the limit of zero applied field is negative ...

Orientation dependence of electromechanical properties of relaxor based ferroelectric single crystals.

The orientation dependence of electromechanical properties of relaxor based ferroelectric single crystals Pb(Zn1/3Nb2/3)O3-(6-7)%PbTiO3 and Pb(Mg1/3Nb2/3)O3-33%PbTiO3 has been calculated by coordinate transformation. Different from previous studies, the optimum cutting orientations have been predicted in terms of their piezoelectric responses in the corresponding crystal planes. The calculation...
