摘　　要：利用蒸发冷凝法，制备了不同平均粒径的Ｆｅ－２９ｗｔ％Ｎｉ合金超细微粒。在不同压强下，将超细微粒压制成片。随压强增大，马氏体体积分数和比饱和磁化强度σｓ明显增大，而矫顽力Ｈｃ呈线性下降。Fe 29wt%Ni alloy ultrafine particles with different average sizes are prepared using evaporation condensation method. Under different pressures, the ultrafine particles are compressed into round slices. As the pressure increases, martensitic volume fraction and specific saturation magnetization, σ s, exhibit marked increase, whereas coercivity, H c, shows a linear decline. There is a close relationship between the pressure effect and average size, .
