| Abstract Scope |
The AlNiCo-5,8H and 9 elemental powders are mechanically alloyed by ball milling. the mechanically alloyed mixture was fed into Tekna for plasma spheroidization at different feed rate and power to study the amount of alloying. XRD was performed to analyze the phase evolution of the alloy powder. Particle size and composition of the alloy powders were analyzed by Scanning Electron Microscopy and Laser Diffraction. Alloyed powders were subjected to additive manufacturing via direct energy deposition to examine the manufacturability. The magnetic properties of the AlNiCo samples such coercivity, remanence and maximum energy product(BHmax) were compared with cast and sintered AlNiCo magnetic properties. Effect of magnetic annealing was brought out as well |
