Abstract
This analytical method development and evaluation was undertaken by the Bureau of Mines to provide accurate determinations of eight minor elements in low-alloy steels prepared from ferrous scrap. Fluorescent x-ray spectrography was the principal method investigated. Confirming analyses were made by conventional instrumental and chemical methods. All x-ray data were processed by a timesharing computer. No corrections were found necessary for interelement effects or overlapping spectral lines. Concentrations were calculated from the least-square fit of a linear calibration equation derived from measurements on three sets of standard steels. These studies show that x-ray spectrographic analysis of lathe- finished surfaces provides accurate determinations of aluminum, copper, chromium, manganese, nickel, phosphorus, silicon, and tin.
