Steel quenching by water under the gas explosion

摘要

By metallorgaphic and X-ray diffractioin methods it was establised that after the steel specimens rapid heating and cooling under the explosion of hydrogen-hydrocarbon gas mixture in water-containing chamber, a slightly etching thin (0.04-0.08 mm) surface layer is formed with high microhardness (12-15 GPa). The structure of the layer contains martensite
