Creep experiments on a rapidly solidified Al-8.5 wt% Fe-1.3 wt% V-1.7 wt% Si alloy (FVS0812) suggest that it exhibits similar or superior deformation resistance compared to other high temperature Al alloys. However, aging at 798 K for 200 h resulted in severe loss of creep strength. Stress reduction results show that FVS0812 exhibits similar creep characteristics to those of other dispersion-strengthened alloys under constant structure conditions following stress reductions, even though the creep mechanism is determined to be significantly different. The operational activation area analysis reveals that the rate-controlling obstacles to dislocation glide are dislocation-dislocation interactions. The role of the particles is to carry a portion of the applied load rather than causing dislocation detachment, local climb, or general climb. This result contradicts the validity of modeling the material using the Rösler-Arzt approach or relying on a threshold stress that is based on the increase in dislocation line length during local or general climb.

在快速凝固的Al-8.5 wt％Fe-1.3 wt％V-1.7 wt％Si合金（FVS0812）上进行的蠕变实验表明，与其他高温铝合金相比，它具有相似或更好的抗变形性能。但是，在798 K下老化200 h导致蠕变强度严重降低。应力降低的结果表明，即使确定蠕变机理明显不同，FVS0812在恒定结构条件下在应力降低后仍具有与其他弥散强化合金相似的蠕变特性。操作激活区域分析表明，位错滑移的速率控制障碍是位错-位错相互作用。粒子的作用是承担一部分施加的载荷，而不是引起位错脱离，局部爬升或总体爬升。
