The Influence of Extraneous Elements in D.C. Arc Spectral of Ferrous Alloys

摘要

The influence of one alloying element upon the spectral line intensity of any other alloying element was subjected to investigation in the D. C. Arc. The study was carried out by making homogeneous metallic alloys in an induction furnace. Manganese, silicon, nickel, chromium, molybdenum, vanadium, aluminum and copper were used as the alloying elements in an iron matrix, with percentage magnitudes commonly found in low alloy steels. It is concluded that: (1) The only influence which could be attributed to any of these elements was that of copper upon the line intensity of manganese. (2) Oxygen contained within the metallic sample has a marked influence on the spectral line intensity of chromium. (3) Some other element or elements not included in this investigation such as carbon, sulfur and/or phosphorus affects the line intensities of nickel, silicon and manganese. (4) Alloys can be melted in an induction furnace without change in chemistry by employing the proper techniques. (Author)
