Influence of heat treatment on mechanical properties and microstructure of AZ61 magnesium alloy

Popis výsledku v původním jazyce

The contribution is focussed on the assessment of the influence of heat treatment of magnesium alloy AZ61 on its mechanical properties and chemical and microstructural heterogeneity. The experimental material was manufactured by the squeeze casting method. The microstructure of the alloy in as cast state was composed of solid solution, intermetallic phase Mg17Al12, and minor Mn-based phases. The heat treatment applied to the alloy was solution annealing at a temperature of 380 C and with graded dwell time from 1 to 16 hours. Chemical etching was employed in order to estimate the micro-segregation of the elements in the matrix qualitatively and to discern the phases in the microstructure. Differences in etching between the central part and the peripheryof crystalline units are apparent in the metallographic images documented by light microscopy. The quantitative assessment of chemical heterogeneity was done via mapping and local chemical microanalyses. The intensity of chemical micro-h
