Comparative study of conventionally sintered Co-Ni-Al alloy with spark plasma sintered alloy
Co-Ni-Al alloy samples were prepared by compacting the powdered alloy at various pressures in proper stoichiometric ratio and the high density compacted alloy was sintered at 673 K. The magnetic, mechanical properties, microstructure and phase analysis were studied and compared with that of...

| Summary: | Co-Ni-Al alloy samples were prepared by compacting the powdered alloy at
various pressures in proper stoichiometric ratio and the high density
compacted alloy was sintered at 673 K. The magnetic, mechanical properties,
microstructure and phase analysis were studied and compared with that of
spark plasma sintered (SPS) alloy. The sintered alloy exhibit martensitic
twin variants with β phase structure. Along with the diffused particle, few
agglomerated clusters were observed on the topographic images. The magnetic
and the mechanical studies of the test specimens were investigated using the
vibrating sample magnetometer, pin on disk tribometer and universal testing
machine respectively. The coercivity value and the ductility of the SPS
alloy are higher than the same of the as-sintered alloy. |
