Dynamic recrystallization of the alloy Fe-40at.%Al-Zr-B
Original language description
On the basis of the uniaxial compression tests realized in the temperature range from 800 °C to 1200 °C and at strain rates from 0.05 s-1 to 30 s-1 the value of the activation energy at hot forming of coarse-grained as-cast iron aluminide Fe 40at.%Al-Zr-B was calculated as Q = 502 kJ.mol-1. With use of this material constant, relatively precise mathematical description of the maximum flow stress and the corresponding strain in dependence on the Zener-Hollomon parameter was possible. At high of the Zener-Hollomon parameter slight decrease in flow stress occurs even without significant course of dynamic recrystallization, which was discovered by metallographical analysis.
