Embodiment 1
[0035] The rapid determination method of the particle size of titanium nitride in the high-speed wire steel of the present invention comprises the following steps:
[0036] 1) The sample is analyzed by spark spectrometry, the time resolution window is opened at 60-350 μs, the sample is sparked 2000 times, and the light intensity measured by the titanium element channel is recorded for each discharge; figure 1 shown;
[0037] 2) Establish a calculation model:
[0038] In order to obtain an accurate average value of normal pulse light intensity, abnormal pulses need to be eliminated successively. Titanium normal pulse (i.e. solid solution titanium part) light intensity I Zi The calculation formulas of the average value Ip and the standard deviation S are as follows formulas 1 and 2:
[0039] I P = Σ I Zi n Formula 1; ...
