and persistent strength of high and low hardness weld joints on P91 steel has been carried out
the results show that: the R weld joint with higher hardness and lower toughness has the higher persistent strength;the D weld joint with lower hardness and higher toughness has lower persistent strength.The persistent strength of material is closely related to the creep life of component.
