Microstructure development of Ca-doped Mg-Zn alloy during hot deformation

Popis výsledku v původním jazyce

Structure and properties of magnesium can be modified by addition of solutes as well as by the metal working operations. To elucidate the alloying effect on both the deformation and the recrystallization mechanism, the present work compares the development of the microstructures of Mg-4Zn and Mg-4Zn-0.4Ca alloys (in wt.%) processed via two different deformation processes: the uniaxial compression (UC) and the equal channel angular pressing (ECAP). The stress-strain curves exhibited the classic evolutionwith the strain rate sensitivity slightly higher for Mg-4Zn than for Mg-4Zn-0.4Ca whereas the absolute value of the stress was higher in case of the ternary alloy during two deformation processes. Microstructure analysis showed that the hot deformationresulted generally in formation of the bimodal structure composed of fine grains of several micrometers and coarse unrecrystallized grains. Moreover, lower strain rates condition led to deformation-induced precipitation. The aim of the cu
