Recent progress in oxide metallurgy technology and its application

The present paper introduces the background, aganinst which the oxide metal- lurgy is put forward, its main content, and effect of this technology on the properties of the structure of steel, and summarizes the research work having been carried out in the recent 10 more years in the aspects of high temperature pinning grain growth and intragranular ferrite, and probes into its mechanism in particular and describes the most advanced technologies and application some of the iron and steel corporations abroad have already developed in this field in the process of high heat input welding and in the mean-while points out the up-to-date progress of research and application of the oxide metal- lurgy in the fields of solidification, press working and production of non-modification steel and heavy plates and foresees the trend of development of this technology.
