| Abstract: | In this paper the quantities of retained austenite in various heat treated 45CrMoNiV alloy structure steel have been measured and studied. A comparison was made b tween the experimental results made by Mssbauer spectroscopy (MS) and Magnetic Method (Mag.M). The effect of selected standard samples in different state on the quantitatire resuit of Mag. M was analyzed. The experimental results show that when magnetic standard sample was correctly selected according to MS the quantities of A_R measured by MS and Mag. M have a good coincidence. As a deduction of this conclusion the correct selection of heat treatment in making Mag. M standard sample was discussed. |
