Description
This paper reports on preliminary work conducted to investigate whether 0.1 at% boron affects the ductility of Ni-rich Ni3Ge (Ni-23.5 at.%Ge). Cracks were observed in the unmodified alloy around hardness indentations and on fresh surfaces upon abrasive cutting. No cracks appeared in the modified alloy. Also, SEM fractographs showed that with the boron addition the morphology changed from pure intergranular fracture to a mixture of intergranular and transgranular fracture, albeit predominantly intergranular. Tensile tests indicated that the boron addition slightly improves the ductility of Ni-rich Ni3Ge
