用急冷方法制备的Nd_4Fe_(77.5)(B_(1-x)C_x)_(18.5)合金带、当x<0.6时为非晶态,x>0.8时是晶态,表明用碳替代硼会使合金的非晶形成能力变差,分析了热处理样品中的晶化相组成。

采用磁控溅射法,在衬底温度为620℃时,通过引入合适的衬底负偏压(100～200V),获得了结晶良好的Ta2O5薄膜,衬底负偏压增强了正离子对衬底表面的轰击作用,加速了其在衬底表面的松弛扩散效应,从而降低了Ta2O5

The effect of trace elements with zero self-interaction coefficient on crystallization temperature of iron carbon alloys was studied and the mathematic equation was developed based on thermodynamics in the present researeh. With the equation developed in this paper, the effects of nitrogen on crysta...
