摘要：

Alloy composition selection for improving creep rupture strength and toughness of reduced activation 9Cr-W steels was investigated. Creep rupture strength increased but toughness decreased with increasing W concentration. Minor additions of V, Ta and B stabilized the fine structure of lath martensite and markedly increased strength without any significant degradation of toughness.
