Abstract
The leaching of Al atoms from B2 structures of mechanically alloyed Ni and Co aluminides led to the formation of metastable B2 Ni and Co. B2 Ni is strong paramagnet not stable above 470 K. The magnetic moment o f Co atom in ferromagnetic B2 phase is smaller than in fcc one. B2 Ni demonstrates high catalytic activity in hydrogenation of organic compo unds.
