Abstract Scope |
The Aluminium and Cerium alloy is fabricated by casting in binary composition of 10-12 wt% Ce and followed by homogenization. Compression testing is appropriate for bulk size Al-12Ce alloy and is utilized in the current investigation. Homologous temperature range (near to 0.5Tm) and dynamic strain rates are selected for testing. Arrhenius equation proposed by Sellars and Tegart is used for constitutive analysis during hot deformation. The activation energy and stress exponent is determined to be 632 kJ/mol and 3.85 respectively. The maximum instability region occurred in the regions of all temperatures between 430°C to 490°C and between the strain rates of 0.001 to 0.01 /sec. The optimum hot working condition of Al-12Ce are all true strain occurs in the temperature range of 430°C to 490°C and strain rate range of 0.1 to 1 /sec with optimum processing window (i.e. maximum power dissipation efficiency) occurs at 470 °C and 0.1 /sec |
