In the paper, results of stress-rupture test applied to MAR-M-509 cobalt alloy specimens, in as-cast condition and with microstructure shaped under rapid solidification conditions are presented. The material for the study were castings of MAR-M509 alloy obtained by means of the investment casting method. The rapid solidification conditions were obtained by means of remelting process carried out with the use of GTAW method. The effect of rapid solidification following the remelting process is a refinement of microstructure in castings of MAR-M509 alloy and significant extension of the time to rupture in stress-rupture test.
