摘要
不采用热压法,用传统的冷压-烧结法也能获高性能B_4C烧结品。B_4C粉末的性质、压制参数、添加剂、烧结气氛、烧结温度等因素对B_4C烧结品的密度、显微组织及抗弯强度有决定性的影响。
An advanced performace B_4C article could also be obtained by traditional cold pressing-sinter-ing method other than hot-pressing. The factors, such as properties of B_4C powder, pressing pa-rameters, additives, atmosphere and temperature of sintering etc. had a key influence on the den-sity, microstructure and bending strength of B_4C articles.
