摘要
提出的块状纳米材料的形成模型可以预测和解释共晶合金的液态Spinodal相分离 ,以及发生的区域和组织 .当液态Spinodal相分离在瞬间发生后 .形成一种纳米材料 ,其晶界与晶粒结合较紧密 ,具有较好的性能 .对合金Fe90 B10 而言 ,当过冷度大于 4 1 6℃时 ,液态Spinodal相分离发生 ,并出现多重Spinodal分解 .晶粒尺寸为 2～ 3nm ,软磁性能为Br=1 .3 0T ,Hc=0 .0 1A/cm .
The model of forming bulk nanomaterials is forecasted and explained by this model that the binary eutectic spinodal phase decomposition, the area and microstructure which occur. The bulk nanocrystalline materials are gained after the liquid spinodal phase decomposition spontaneously, and are of good properties. For the alloy of Fe 90 B 10 , when the undercooling temperature is more than 416?℃, the spinodal decomposition of Fe 90 B 10 occurs spontaneously many times, a nanocrystalline material with 2～3?nm grain is gotten, and the soft magnetic properties are B r=1.30?T, H c=0.01?A/cm.
