It is found that the creep curves of alloy K46 consist mainly of a longer steady-state creep stage and an accelerated creep stage, which occupies the most creep strain.
K 46合金的高温拉伸蠕变曲线表现出非常长的稳态蠕变阶段,而较高的蠕变塑性来自于加速蠕变阶段。
Through introducing the nonlinear viscoplastic component, this rheological model can describe the transient creep stage, steady-state creep stage and tertiary creep stage.
