摘　　要：研究了稀土、钒钛复合变质处理对钨合金白口铸铁组织和性能的影响。结果表明,变质处理后钨合金白口铸铁的微观组织中碳化物网络断裂,其抗冲击韧性和耐磨损性能显著提高。In the present work, the microstructures and properties of W-allouying white cast iron modified by RE, V and Ti was studied. The results show that the carbide networks in microstructure tend to break, and fracture toughness and wear-resisting properties of the alloy were improved.

关 键 词：钨合金白口铸铁 钒钛复合变质处理 抗冲击磨损性能
