Cyclic Characterisation and Plasticity Modelling of AM30

Anisotropic fatigue and cyclic behaviour of AM30 Mg alloy extrusion is investigated by performing fully-reversed strain-controlled tension-compression cyclic tests at strain amplitudes between 0.3% and 2.3%, along extrusion (ED) and transverse (TD) directions. Cyclic Deformation Behavior of a Rare-Earth Containing Dec 04, 2014 · The present study was aimed at evaluating strain-controlled cyclic deformation behavior of a rare-earth (RE) element containing Mg-10Gd-3Y-0.5Zr (GW103K) alloy in different states (as-extruded, peak-aged (T5), and solution-treated and peak-aged (T6)). The addition of RE elements led to an effective grain refinement and weak texture in the as-extruded alloy. While heat treatment resulted

Influence of Rolling Reductions on Recrystallization

Abstract:The recrystallization texture in commercially pure Al is investigated after the samples are rolled differently and annealed.The samples with low rol- ling reductions could be generally recovered or recrystallized in situ and characterized by the re- tained G{110}. 001>component.This recovery process decreases during annealing with the increase of reduction.The appearance of the B/R{359}. Low cycle fatigue behavior of the extruded AZ80 The yield asymmetry complicates the cyclic deformation and fatigue properties of wrought magnesium alloys. The cyclic deformation and fatigue properties of wrought magnesium alloys have been reported in many studies. The rare-earth element containing extruded magnesium alloys GW123K [8] and GW103K [9] showed symmetric hysteresis loops under fully reversed strain controlled cyclic deformation, Mechanistic origin and prediction of enhanced ductility in Jan 26, 2018 · The deleterious effect of Zn also corroborates the texture evolution during rolling, where the DPRD texture, driven by . slip in Mg-Ce (33, 34), Mg-Y , and Mg-Ca (19, 36), weakens or disappears upon additions of Zn (13, 19, 37). However, alloying with dilute RE solutes can easily yield > 1 at low Zn concentrations.

Risks and Complications of Breast Implants FDA

Sep 28, 2020 · Asymmetry:The breasts are uneven in appearance in terms of size, shape or breast level. Extrusion:The skin breaks down and the implant appears through the Tension-compression-tension tertiary twins in coarse Apr 07, 2015 · The microstructure, texture and mechanical properties were evaluated by electron backscattering diffraction and mechanical test. The results showed that the corresponding yield strengths for as-extruded fine-grained pure Mg were 130.8 MPa in tension and 125.6 MPa in compression, leading to a greatly improved yield asymmetry ratio.British Library EThOS:Thermomechanical processing of Extrusions showed low ambient yield asymmetry. The highest measured yield stresses were correlated with partial RX. These two observations can be explained by a balance of texture, Hall-Petch strengthening and work hardening. One unexplained observation of note is that the maximum observed yields generally correspond to a reversed yield asymmetry.
