B对Cr27型高铬白口铸铁组织和性能的影响
Effect of Boron on Microstructure and Properties of Cr27 High Chromium Cast Iron
摘要
Abstract
This study aimed at optimizing hardness,impact toughness and abrasion wear resistance of G28 chromium cast irons by changing the content of boron.The erosion wear mechanism explained by this experiment.The results show that with the increase of boron content,the carbide gradually coarsen and the erosion performance of high chromium white cast iron gradually deteriorate.When the boron addition is 0.5％,comprehensive mechanical properties of cast iron exhibits desirable.关键词
