Hot Deformation Behaviors and Processing Maps of

The isothermal hot compression tests of as-cast and homogenized 2024 aluminum alloy were carried out under wide range of deformation temperatures (623-773 K) and strain rates (0.001-10 s1). The constitutive equations for both initial states were established based on Arrhenius model, and the processing maps were constructed based on the dynamic material model. A Characterization for the Deformation Behavior of As-Cast Thus, the application of the as-cast P91 alloy steel constitutive model on the CHE hot extrusion process should be further studied and explored. The finite element (FE) method is the efficient and economical alternative method for studying the flow stress behavior during hot deformation [1921]. Hence, the constitutive model of the as-cast

An evaluation of H13 tool steel deformation in hot

H13 tool steel behaviour under elevated temperature and excessive load (Miland and Panasiuk 1982). The understanding of the non-uniform deformation and work hardening of the material is of critical importance. Deformation at high temperature on the tool is down to the localise stress and strain Behavior of Hot-Mix Asphalt Containing Blast Furnace Slag Significant amounts of blast furnace slag (BFS) are generated daily as by-product from iron and steel industries. This waste material usually has interesting physical properties and mineralogical and chemical composition, which can be useful as granular aggregate in the production of hot mix asphalt (HMA). Effect of Deformation Temperature on Microstructure

  • AbstractIntroductionExperimental ProcedureResults and DiscussionConclusionsConflicts of InterestThis work addresses the influence of deformation temperature in a range from 40°C to 200°C on the microstructure evolution and mechanical properties of a low-carbon high-manganese austenitic steel. The temperature range was chosen to cope at the time during sheet processing or car crash events. Experimental results show that yield stress and ultimate tensile strength gradually deteriorate with an increase in the tensile testing temperature. The dominant mechanism responsible for the strain hardeniNon-isothermal deformation behavior and FE simulation of Apr 08, 2016 · In the current work, the effects of initial deformation temperature and strain rate on flow behavior and microstructure of boron-alloyed steel after non-isothermal deformation were investigated. Based on the stress-strain curve obtained in the non-isothermal tensile experiment with a Gleeble 3500 system, finite element software was used to carry out the thermal mechanical coupled simulation of
