Cal Poly
An Experimentally Generated Constitutive Model for Peak Stress (σ_peak) in Compression Samples
Abstract
dc:description.abstract<p>The hot working behavior of AISI 1018 steel was studied by hot-compression deformation tests on the Gleeble 1500 thermo-mechanical simulator at true strain values of -0.143 and -0.405, true strain rate values of 0.01 and 0.1, and working temperatures of 900<sup>°</sup>C and 1000°C. The tests show that a lower working temperature and lower true strain value results in a greater maximum compressive force. The apparent activation energy <em>Q<sub>app</sub></em> was calculated by using the Zener-Hollomon parameter combined with the low stress law. <em>Q<sub>app</sub></em><sub> </sub>was calculated to be 311 kJ mol<sup>-1 </sup>K<sup>-1</sup>.</p>
