The mathematical model of the mean flow stress for MgAl3Zn1Mn magnesium alloy

Popis výsledku v původním jazyce

Purpose: The presented paper deals with method for determination of mean flow stress (MFS) which contributes to better knowledge of forming processes of hot formed magnesium alloys. Methodology: An experiment leading to obtaining the model of the mean flow stress (MFS) of magnesium alloy AZ31 was realized in laboratory rolling mill. It resulted from mathematical and statistical processing of MFS values that these could be described by a simple function of just two independent variables ? temperature (200 to 450 °C) and equivalent height strain (approx. 0.2 to 0.7). The methods of the light microscopy for metallographic analyses were used. Findings: The increasing strain resulted in decreasing deformation resistance. The effect of equivalent strain rate(approx. 10 ? 80 1/s) was negligible. The model describes the given relationship with good accuracy; a relative error of calculated MFS values does not exceed ?10 %. Research limitations/implications: In future work an important relation
