    Feb 15, 1999· Ballmilling conditionswere examined for the preparation of fine Nd(Fe,Mo) 12 N x particles. Themillingprocess with high ratio of ball to powder produced Nd(Fe,Mo) 12 N x particles with low iH cand4πI r. The decrease in 4πI randiH c was attributed to population of α-Feandparticle aggregates that were formed during themilling.The addition of process control agents (PCA, e.g. stearic acid) prevented aggregation in the ballmilling,…
