A Method for the Determination of Cr, Mn, Mo, Ni, and B in Low Alloy Steel Armor Using Atomic Absorption Spectroscopy and Inductively Coupled Argon Plasma Emission Spectroscopy
Abstract
A more reliable, accurate, and rapid method to determine the concentration of chromium, manganese, molybdenum, nickel, and boron in low alloy steel armors is described. The various procedures of sample dissolution by acids are given. For each element, the high and low intensity spectral lines are determined for the analytical ranges of interest. Analytical results using spiked standards and standard reference materials from the National Institute of Standards and Technology are in agreement with the certified values. The strength and resistance of an armor steel to ballistic impact can be strongly dependent on the microstructure as well as the alloying elements. The purpose of this study is to develop a simple analytical procedure that yields the high accuracy of atomic absorption spectrophotometry and the speed of inductively coupled argon plasma emission spectrometry, using a minimum of analytical steps in sample preparation, dilution, and wet chemical procedures.
