【Abstract】 The strength and loughness of high-strength steels used for roundlinkchain making in the coal mining industry were measured in quenohed and tem-pered conditions. By means of stepregressional equations the compositions andpropemties of the steels were obtained. Using X-ray diffraction and transmissionelectron microscopy as well as electron diffraction, the effect of alloying elementsou strength and toughness of the investigated steels was studied.更多还原
