Influence of the methodology of mathematical processing of experimental data on the calculated value of the activation energy in hot forming was evaluated for three very different alloys: iron aluminide. low-alloyed steel and magnesium alloy. Application of the mean strain rates is appropriate but calculations with use of nominal strain rates of the plastometric tests do not give sign... https://www.roneverhart.com/Christmas-Ornament-Ice-Ball-Molds-Design-Set-Options/
