摘要
Effects of the quenching rate and annealing temperature on hard magnetic properties of rapidly quenched Co_(84-x)B_(x)Zr_(16)and Co_(82-x)Fe_(x)Zr_(18)alloys were studied.The B-or Fe-content dependence of room temperature coercivity H_(c),remanence B_(r) and maximum energy product(BH)_(max) are obtained.The H_(c) is suggested to originate from the microstructure with the optimal grain size.
