Abstract

In order to study the effects of oxygen and carbon on mechanical properties in a-iron, tensile test were done on the specimens with various oxygen contents and on the carburized specimens with various oxygen contents.
The results obtained here are as follows:(1) Yield point is lowered with the increase of oxygen content.(2) Ky value that is the coefficent of the grain size dependent term in PETCH relation σy=σi+Kyd-1/2, isaffected by oxygen, but σi is not.(3) In carburized specimens with various oxygen contents, the yield point is increased by carburizing and lowered with the increase of oxygen content.
