It has been proved that the interstitially dissoled amounts of N and C can be quantitatively measured from the Snoek peak height by using the transverse vibration method at about 600 c/s. The proportional coefficient between the dissolved amounts of N or C and the Snoek peak height is influenced by grain size and impurities, but the following relations, practically wt% N or C=0.00434×Tn×(Q−1)max or 0.00430×Tc×(Q−1)max, are shown, where Tn or Tc are the peak temperature of N or C and (Q−1)max is the Snoek peak height. It has also been ascertained that the Snoek peak height is inversely propotional to the peak temperature between a hundred and several thousand c/s as predicted theoretically.
