含硼白口铸铁的研究进展

Development of Boron-Bearing White Cast Irons

综述了硼对白口铸铁显微组织、力学性能和耐磨性的影响规律,着重介绍了硼系白口铸铁、含硼高铬铸铁和含硼低合金白口铸铁的组织和性能,分析了硼提高白口铸铁力学性能和耐磨性的原因,提出了扩大含硼白口铸铁应用值得重视的问题。

The effect of boron on the microstructures, mechanical properties and abrasive wear resistance of white cast iron has been summarized. The microstructure and properties of B-bearing white cast iron, B-bearing high chromium cast iron and B-bearing low alloy white cast iron have been introduced in detail. The reasons that boron can improve the mechanical properties and abrasive wear resistance of white cast iron have been analyzed. At last, many problems that should pay attention to have been put forward in order to enlarge the application of B-bearing white cast irons.
