We present a new class of TiBw/Ti6Al4V composites with a network reinforcement architecture that exhibits a significant creep resistance compared to monolithic Ti6Al4V alloys. Creep tests performed at temperatures between 773 K and 923 K and stress range of 100 MPa-300 MPa indicate both a significant improvement of the composites creep resistance due to the network architecture made by the TiB ...

Underground caverns in rock salt deposits are the most secure disposal method and a type of gas-storing facility. Gas storage plays a vital role in ensuring that a strategic relationship is secured between an established energy infrastructure provider and a midstream energy company. The Fischells Brook area is a pillow-shaped body of salts located in the St. George's Bay area of southwest Newfo...

Creep response in a rotating disc made of anisotropic Al-SiC(particle) composite having linearly varying thickness has been carried out using anisotropic Hoffman yield criterion in present study. The steady state creep behavior is described by Sherby’s constitutive model. The material parameters characterizing difference in yield stresses have been used from the available experimental results i...

[1] We present high-resolution measurements of interseismic deformation along the central section of the North Anatolian Fault (NAF) in Turkey using interferometric synthetic aperture radar data from the Advanced Land Observing Satellite and Envisat missions. We generated maps of satellite line-of-sight velocity using five ascending Advanced Land Observing Satellite tracks and one descending En...

In order to research the creep deformation characteristics of frozen soil and effect various influencing factors on creep, indoor uniaxial tests were carried out specimens at temperatures −5, −4, −3 −2 °C under loads 0.25, 0.5, 0.75 σt, respectively. The different load conditions are analyzed unconfined conditions. results show that test conditions, when is low, there no accelerated stage in cu...

Fitting data to classical creep rupture models can result in unrealistically high extrapolated long-term strength. As a consequence, the standard strength values for new steel grades have frequently needed downward correction after obtaining more long-term test data. The reasons for non-conservative extrapolation include the influence of short-term data, which are easiest to produce but tend to...

Introduction: Simple models of geomorphic modification of planetary surfaces by erosion or deposition are reported here. These processes are linear and non-linear creep, uniform accrescence and decrescence, and non-linear airfall deposition. They do not include models of flow whose depth is of the same order of magnitude as the landform, such as glacial flow or relaxation of crater forms in pla...

Reactive infiltration processing was used to fabricate bulk NiAl and fiber-reinforced NiAl composites. Homogenous, pore-free materials were obtained by chemical reaction between nickel and aluminum after complete infiltration with liquid aluminum of preforms of nickel wires (containing tungsten wires for the composites) with low surface-to-volume ratio, high permeability, and regular infiltrati...

Title of Dissertation: CREEP CORROSION OVER PLASTIC ENCAPSULATED MICROCIRCUIT PACKAGES WITH NOBLE METAL PREPLATED LEADFRAMES Ping Zhao, Doctor of Philosophy, 2005 Dissertation Directed By: Dr. Michael Pecht, Professor, Department of Mechanical Engineering Field failures were observed to be caused by the bridging of corrosion products across lead fingers. This phenomenon was identified as creep ...

Transport as well as magnetic relaxation properties of the mixed state were studied on strongly underdoped Y12xPrxBa2Cu3O72d crystals. We observed two correlated phenomena—a coupling transition and a transition to quantum creep. The distribution of transport current below the coupling transition is highly nonuniform, which facilitates quantum creep. We speculate that in the mixed state below th...
