Fe-P-N 合金中的 Snock-Kê-Kster峰

Snock K Kster Peak in Fe P N Alloys

研究了变形Ｆｅ－Ｐ－Ｎ合金的内耗和沉淀，发现含置换元素磷的三元系铁的ｈｈＳＫＫ／ｈＳ比值不是给定值，而是磷含量的函数．在ｃＮ≤０．００３质量百分数％，ｃＰ≤０．０６４质量百分数％时，存在关系式ｈｈＳＫＫ／ｈＳ＝Ｋ１ｃ（－２／３）Ｐ＋Ｋ２，截距Ｋ２产生的原因是由于固溶合金基体中存在磷原子对和气团．

The internal friction and precipitates in the deformed Fe P N alloys have been studied. It is found that for the trinary iron containing phosphorous of substitutional element,the ratio h SKK / h S is not a given value,but a function of phorphorous content,and under the experimental conditions of the N content <0 003% and the P content <0 064%,there exists a relationship: h SKK / h S =K 1 c P -2/3 + K 2 . It is pointed out that the occurance of the intercept K 2 is due to the existance of P pairs and clusters in the matrix of the alloys of solid solution.
