Abstract
In this study, ductile Ni-resist with a minimum nickel content of 18Â wt% was modified. Up to 12Â wt% manganese was added together with 10Â wt% nickel to investigate the effects of the alloying elements on the solidification, microstructure and mechanical properties of the Ni-resist. The effects of the solidification stage on the primary dendrite arm spacing (DAS), secondary dendrite arm spacing (SDAS), graphite aggregates, carbide formation and a series of mechanical properties were evaluated. The results indicate that the DAS, SDAS, graphite aggregate and carbide are directly dependent on the solidification cooling rate. Consequently, various mechanical properties of the Ni-resist are also affected by the addition of manganese. The tensile strength of the modified ductile Ni-resist decreased as the manganese content increased.
