Tests were conducted on samples of MAR-M-509 alloy castings, obtained using the lost-wax method. Casting structure refining was performed with the GTAW method in argon atmosphere, using the current I = 200 A and electrical arc scanning velocity vs = 100, 150, 200 and 250 mm/min. The effect of rapid resolidification of the MAR-M-509 alloy on the microstructure was examined and significant improvement in stress rupture test was observed.}, type={Artykuły / Articles}, title={Stress Rupture Test of MAR-M509 Alloy with Structure Refined by Rapid Resolidification}, URL={http://www.journals.pan.pl/Content/87135/PDF/20_paper.pdf}, doi={10.2478/v10266-012-0118-6}, keywords={MAR-M-509 alloy, Rapid resolidification, microstructure, Stress rupture test}, }
