Hot deformation of cast-homogenized and extruded (in both the extrusion transverse directions) ZK60 magnesium alloy was conducted using Gleeble® 3500 thermal-mechanical simulation testing system. A new approach to model high temperature constitutive behavior done two well-known equations (i.e. hyperbolic sine Ludwig equations). For this approach, conditions were divided into regimes low strain rate (four regimes). Constitutive development in each regime material parameters (P) evaluated as...
A novel variable temperature range, shear range in-situ processing cell is used to examine crystallization and polymorphic phase transformations in cocoa butter fat. Under static conditions, polymorphs III IV are observed, while under sheared conditions V present at a specified of temperatures. Increased shearing rate significantly raises the which observed resulting an associated reduction induction times. Also, as base holding lowered times for forms decrease (depending on whether sample sheared).
The hot deformation behavior of dual-phase Mg–9Li–3Al alloys was investigated by the isothermal compression tests using Gleeble-3500 thermal-mechanical simulation testing system over a temperature range from 473 to 623 K and strain rate 0.001–1 s−1. flow curves exhibited obvious serrations periodic fluctuation at high rates, which can be considered as Portevin-Le Chatelier effect. relationship among stress, rate, analyzed. activation energy (Q) some basic material factors (A, n, α) were...
The effect of set-back distance on the thermo-mechanical behavior strip during twin roll casting (TRC) an AZ31 magnesium alloy was modeled using finite element method (FEM). Model validation done by comparing predicted and measured exit surface temperature as well secondary dendrite arm spacing (SDAS) through thickness sheet to those experiments. results showed increases, decreases solidification front moves toward entry gap. cast also experiences more plastic deformation consequently,...
