It’s estimated that 750,000 new hybrid electric and plug-in battery vehicles have taken to the road in 2016 alone, coupled to sustained 40% growth annually. Producing permanent magnets on the scale of tens of millions with a consistent, predictable low cost is now as important as ever, something import-reliant rare earth permanent magnets (PM) have struggled to achieve. Thus, a suitable replacement PM material must be developed for sustained growth of electric drive vehicles. Alnico, with its high saturation magnetization and thermal stability, appears well suited for improvement because of recent coercivity enhancements and innovative pre-alloyed powder processing with abnormal grain growth (AGG) for solid state texture development. Both an applied magnetic field and uniaxial loading (during AGG) have been used to develop a highly desired texture in the resulting microstructure of near-final shape magnets through various mechanisms.
