We　report　a　magnetically-anisotropic　PrCo5　permanent　bulk　magnet,　prepared　by　a　hot　deformation　method,　with　crystallographic　orientation-dependent　magnetic　properties.　Although　the　PrCo5　crystals　strongly　favor　the　{0001}　orientation　texture,　the　crystallographic　orientation　textures　of　PrCo5　crystallites　differ　at　various　radial　locations.　From　the　bulk　center　to　the　edge,　the　c-axis　orientation　texture　decreases　from　5.4　MRD　to　4.1　MRD,　whereas　the　remanence　decreases　from　8.93　kGs　to　7.58　kGs　and　the　coercivity　increases　from　4.34　kOe　to　6.56　kOe.　This　paper　also　reports　the　alteration　of　boundary　plane　orientation　textures,　resulting　from　the　corresponding　energy　anisotropy　at　different　locations,　and　suggests　that　the　development　of　grain　boundaries　with　lower　boundary　energies　has　a　significant　impact　on　the　magnetic　properties　with　regard　to　remanence　and　energy　density.　The　current　work　therefore　proposes　an　elegant　approach　to　attain　desired　magnetic　properties　in　PrCo5　magnets　by　fine-tuning　the　crystallographic　orientation.
