Thermal stability of multi-spray deposition heat resistant Al-Fe-V-Si alloy
摘要
Rapidly solidified Al-8.4Fe-1.3V-1.7Si heat resistant alloy was made by using multi-layer spray deposition technique.Its thermal stability of mechanical properties was investigated by the means of tensile and hardness tests,thermal stability of microstructure by transmission electron microscopy (TEM),X-ray diffraction (XRD).The results show that after heat exposure (HE) at 753 K for 500 h the tensile strength and hardness of Al-Fe-V-Si alloy at 623 K maintains the same values as those at room-temperature.HE dose not obviously affect the thermal stabilities of Al12(Fe,V)3Si phase but the lattice constant of Al12(Fe,V)3Si phase decrease.
