MnLiZnフェライト顆粒の強度と圧縮挙動

抄録

MnLiZn ferrite granules of different strength were prepared by changing either amount of binder or kneading time. Rates of compaction of these granules in a die were expressed by following two equations.
First step, ε=k'logt+k₀(1)
and second step, log(1+k₁logε)=k₂t+k₃(2).
Relations among the strength of granules and coefficients in equations were discussed. Not only the strength but also methods of preparation were effective for the change in values of coefficients. Effects of size of granule on these values of coefficients and sintering behavior of compacts were also studied.
