1Microstructure of AISI 304 stainless steel strips produced by a twin-roll caster显示文摘By optical inspection of macro-etched metallography and electron back-scattered diffraction (EBSD) mapping, this paper analyzed the microstructure of austenitic stainless steel strips produced with an equal-diameter twin-roll strip caster. The results in-dicate that the microstructure of the strips includes two columnar zones with highly compact dendrites and one equiaxed zone. The characteristics, such as grain size and growing direction of columnar grains and equiaxed grains, were investigated. An additional transitional area with many finer grains between the columnar zone and the equiaxed zone was found. As shown in EBSD analysis, small angle boundaries exist both in the columnar zone and the equiaxed zone, although they are especially more in the transitional area. Additionally, some <111> twin boundaries were found in the microstructure of the strips.Chenxi Ji Jiongmmg Zhang Fuxiang Huang Xinhua Wang Yuan Fang Yan Yu 2008Journal of University of Science and Technology Beijing2008,15,6:1
