| Abstract: | The large-size 650/360×1200mm high-temperature Al-8.5Fe-1.3V-1.7Si alloy tubes are prepared by multi-layer spray deposition.The results show that the technology can gain high cooling rate,fine microstructure,and makes little change to microstrure as the wall-thickness increass.After being extruded,σ bat room temperature of the multi-layer spray-deposited tube can reach 445MPa and σ bat 350℃ 195MPa.The results are higher than that of the same material produced by Ospery technology. |
