Nanocrystalline Nd2Fe14-xMxB (M = Ti, Nb) magnets were prepared by mechanical alloying and respective heat treatment at 973 K/30 min. Refractory Ti and Nb elements, introduced to the parent alloy results in an increase of coercivity. This effect is directly connected with structure refinement. Addition of Ti0.5 and Nb0.75 results in increase of coercivity from 796,2 kA m^-1 to 1114,7 kA m^-1 and to 1035,1 kA m^-1, respectively.

Nanokrystaliczne magnesy typu Nd2Fe14.xMxB (M = Ti, Nb) wytworzono stosując mechaniczną syntezę i obróbkę cieplną w 973 K/30 min (Rys. 1). Wprowadzenie pierwiastków trudnotopliwych takich jak Ti, Nb do stopu rodzimego powoduje znaczący wzrost koercji (Rys. 2, Rys. 3), wynikający z rozdrobnienia mikrostruktury. Dodanie Ti05 i Nbo.75 powoduje wzrost koercji z wartości 796,2 kA m"1 dla stopu rodzimego do odpowiednio 1114,7 kA m"1 i 1035,1 kA m"1.
