An Experimentally Generated Constitutive Model for Peak Stress (σ_peak) in Compression Samples

Galang, Kevin Mathew Lopez 01 May 2013 (has links) (PDF)
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°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 Qapp was calculated by using the Zener-Hollomon parameter combined with the low stress law. Qapp ­was calculated to be 311 kJ mol-1 K-1.
