Применение позитронной аннигиляционной спектрометрии для изучения изменений в стали 40CrNiMoA после высокоскоростной резки

Abstract

40CrNiMoA steel is an important structural steel with high strength, corrosion resistance and good impact strength. It is used in a wide range of industrial applications to produce strong structures and parts capable of operating in harsh environments. The formation of a white layer on the material surface during high speed cutting is one of the problems associated with machining steel products. It has been shown that white layer formation depends on various high-speed cutting parameters including cutting speed, feed and depth of cut. Variations in these parameters affect the thickness and structure of the white layer as well as the properties of the steel being machined [1]
