Es. Gorkunov et al., EDDY-CURRENT INSPECTION OF THE TEMPERING QUALITY OF THIN-SHEET CARBON-STEEL PARTS WITH VARIATIONS IN CARBON CONTENT, Russian journal of nondestructive testing, 29(3), 1993, pp. 213-216
The possibility of eddy-current inspection of the quality of medium-te
mperature tempering of carbon steel parts with a change in carbon cont
ent from 0.4 to 0.82% is shown. A method of eddy-current inspection of
the heat-treatment quality of thin-sheet carbon steel parts with vari
ations in carbon content from 0.62 to 0.82% has been developed.
