Abstract

Simultaneous determination of chromium and manganese in some low alloy steels and stainless steels was investigated. The background correction method was applied to chromium Kβ line and manganese Kα line. The equation for the correction of background were obtained as follows, XMn=CMn−0.226CCr⁄0.951 and YCr=CCr−0.219CMn⁄0.951. (X,Y…true X-ray intensity, C…observed X-ray intensity). with these equations and calibration curves, chromium and manganese in low alloy steels and 25% chromium-20% nickel steels were determined.
