EFFECT OF AGING TREATMENT ON THE STRUCTURE AND PROPERTIES OF RAPIDLY SOLIDIFIED Al-8.23Fe-3.62Ce ALLOY
时效处理对快速凝固 Al-8.23Fe-3.62Ce 合金结构与性能的影响

The effect of aging treatment on the structure and mechanicalproperties of Al-8.23Fe-3.62Ce alloy was studied by hardenss,ambient tem-perature tensilc test and transmission electron microscopy.It was found that ag-ing for 6h at 573K did not result in marked phase precipitation and coarsening.The tensile strength of the alloy did not degrade after aging for 30h at sametemperature.Rapid coarsening of precipitates after prolonged aging at 673K re-sulted in the degradation in room temperature tensile strength.
