The relationship between modern material design and study of phase diagram is introduced and it is emphasized that the appearance of CALPHAD made the study of phase diagram be one part of material design. It is also pointed out that the other important function of CALPHAD system is to evaluate and optimize thermodynamic parameters. The importance of phase diagram study in material design is illustrated by examples of development of nanocrystalline materials with two phases, wide hysteresis shape memory alloys,...

Phosphating→dipping painting/ spraying method is adopted to those small and abnormal shaped bonded Nd-Fe-B magnets which are not suitable for ED coating. The corrosion resistance of Bonded Nd-Fe-B magnets treated by this method is appraised. Bonded Nd-Fe-B; Salt spray resistance; Heat and humidity resistance; Dipping painting / spraying

 提出了对不适宜电泳涂装的异形小体积粘结钕铁硼工件采用磷化→浸涂/喷涂方式进行防腐蚀涂装的一种方法,评价了用这种工艺路线所制备的工件的抗腐蚀特性。

The effect of tempering process on the microstructure and magnetic properties of sintered Nd-Fe-B magnets were investigated.It was manifested that when the tempering temperature was below 910℃,the Nd-rich phase on grain boundary gathered and a wide band of the Nd-rich phase formed,the volume fraction of matrix phase was small and so the magnetic properties of the magnets were low.When the temperature was above 930℃,the grain size became coarse,the grain boundary area...

The effect of tempering process on the microstructure and magnetic properties of sintered Nd-Fe-B magnets were investigated.It was manifested that when the tempering temperature was below 910℃,the Nd-rich phase on grain boundary gathered and a wide band of the Nd-rich phase formed,the volume fraction of matrix phase was small and so the magnetic properties of the magnets were low.When the temperature was above 930℃,the grain size became coarse,the grain boundary area became smaller,the band of the Nd-rich phase on grain boundary became wider and the magnetic properties of the magnets were deteriorated.When the temperature is between 910℃ and 930℃,the grain size was inclined to be uniform,the content of clustered Nd-rich phase reduced,the magnetic properties of magnets were optimized.So the proper temperature for the first tempering of Nd30Dy3.5Al0.2B1 alloy shall be from 910℃ to 930℃.

探讨了880~900℃、910~930℃、940~960℃温度区间下1h回火处理对Nd30Dy3.5Al0.2B1合金显微组织和磁性能的影响。研究表明,温度低于910℃时,晶界富Nd带过厚且积聚,主相体积分数小,矫顽力、磁能积低;温度高于930℃时,晶粒尺寸过大,晶界面积变小,晶界富Nd带加厚,矫顽力、磁能积均下降;910~930℃时晶粒尺寸趋向均匀,晶界富Nd带呈薄层状分布,磁性能最佳。
