OPTIMIZATION OF SINTERING CONDITIONS FOR THE PREPARATION OF POROUS MAGNESIUM

Popis výsledku v původním jazyce

In this paper we focused on the influence of sintering conditions; purity of argon atmosphere and sintering time namely, on microstructural and mechanical characteristics of porous magnesium prepared by powder metallurgy. An argon with technical purity (99.996 vol.%) and argon purified by a magnesium getter were used as the sintering atmospheres. The samples were sintered for different times (0, 3, 6, 12 and 24 h). Subsequently, microstructure, flexural and compressive behaviour were investigated in detail. The type of used atmosphere had no significant influence on the studied characteristics after sintering up to 6 h and the mechanical properties increased with longer sintering time. On the other hand, after sintering longer than 6 h, mechanical properties of the samples sintered under the purified atmosphere increased with longer sintering time, while the use of technical argon decreased mechanical properties significantly and slightly increased porosity. It was caused by oxidation,
