The development of advanced creep constitutive equations for high chromium steel P91 at low stress range [PDF]
, 2013 Diffusion dominates the creep deformation at low stress range for high chromium steel P91. Brittle creep fracture is caused by cavity nucleation, growth and coalescence of cavities and large precipitates (Laves phase and M23C6) at grain boundary under ...

HIGH STRAIN RATE LOADING OF ZIRCALOY
Le Journal de Physique Colloques, 1985 High strain rate tensile loading behaviours of Zircaloys subjected to various treatments were investigated at room temperature and at 300°C, and compared with those of static cases. It was observed that the dynamic stress-strain profiles were different depending upon the specimen treatment and that the higher peak stress and the lower sectional area ...

Effect of high strain rate on micro-indentation test in pure aluminum
EPJ Web of Conferences, 2012 The indentation properties of pure aluminum (99.9%, 3N aluminum) and high purity aluminum (99.999%, 5N aluminum) with respect to the strain rate dependence of strength are experimentally investigated in order to clarify the effect of strain rate on the ...

Retention of ductility in high-strength steels [PDF]
, 1969 To produce high strength alloy steel with retention of ductility, include tempering, cooling and subsequent tempering. Five parameters for optimum results are pretempering temperature, amount of strain, strain rate, temperature during strain, and ...

Decoherence of electron spin qubits in Si-based quantum computers
, 2002 Direct phonon spin-lattice relaxation of an electron qubit bound by a donor impurity or quantum dot in SiGe heterostructures is investigated. The aim is to evaluate the importance of decoherence from this mechanism in several important solid-state ...

A novel method for severe plastic deformation at high strain rate
EPJ Web of Conferences, 2018 Severe plastic deformation (SPD) processing is defined as any method of forming under an extensive hydrostatic pressure that may be used to impart a very high strain to a bulk solid without any significant change in dimensions of the sample, producing ...

High Strain-Rate Material Model Validation for Laser Peening Simulation
The Journal of Engineering, 2015 Finite element modeling can be a powerful tool for predicting residual stresses induced by laser peening; however the sign and magnitude of the stress predictions depend strongly on how the material model captures the high strain rate response.

Quasi-Static and High Strain Rates
Procedia Engineering, 2011 AbstractCylindrical samples of a 0/90° cross-ply Nextel 610™/Al-6061 (∼55Vf%) metal matrix composite have been subjected to compression testing at quasi-static and high strain rates over a range of angles between 0° and ±45° with respect to the principal fiber directions.

Validating performance of automotive materials at high strain rate for improved crash design [PDF]
, 2006 This paper investigates sources of performance variability in high velocity testing of automotive crash structures. Sources of variability, or so called noise factors, present in a testing environment, arise from uncertainty in structural properties ...
