Notes:
A new method for the determination of inclusions of boron and titanium in medium andlow alloy steel has been reported in this paper. The technique of original position statisticdistribution analysis based on statistic analysis of more than ten thousands primary optical signals isapplied in the present method. It is found that the abnormal high intensities in emission lines ofboron and titanium occurred when a discharge volatilizes the material containing inclusions ofboron and titanium. Some statistic algorithms are developed to distinguish the signals related tononmetallic inclusions from the signals generated from soluble boron and titanium. Furthermore,mathematical models based on the relationship between the frequency of abnormal sparks andcontent of inclusions is put forward in this paper to count the contents of inclusions of boron andtitanium. The results calculated by the present model have good coincidence with the valueobtained by chemical methods. The present method has been applied to the determination of thecontents of inclusions of boron and titanium in some certified reference materials and some realmedium and low alloy steel samples
