| 摘 要： | 通过扫描电镜和透射电镜分析研究了原位反应生成的TiC颗粒对喷射成形态及挤压态的Al-8.5Fe-1.4V-1.7Si合金显微组织的影响,并对合金的力学性能进行了测试。结果表明,原位反应生成的TiC颗粒均匀地分布在合金基体中并细化了基体合金的晶粒,提高了合金的高温组织稳定性;喷射成形Al-8.5Fe-1.4V-1.7Si 3.0TiC合金挤压态的室温和高温强度明显高于喷射成形Al-8.5Fe-1.4V-1.7Si合金挤压态的强度,而且塑性也有明显的提高。 |

| Abstract: | The effects of TiC particles formed by in-situ reaction on the microstructure of spray formed and extruded Al-8.5Fe-1.4V-1.7Si alloy were studied and analyzed by means of SEM,TEM.The mechanical properties of the alloy were also tested.The results show that the TiC particles formed by in-situ reaction distribute homogeneously in the alloy matrix,they can refine grains and effectively control grain size .The microstructure stability of the alloy at high temperature is improved.The strength of the spary-formed Al-8.5Fe-1.4V-1.7Si 3.0TiC alloy as-extruded at room temperature and high temperature is higher than that of Al-8.5Fe-1.4V-1.7Si alloy in the same condition.The elongation of the Al-8.5Fe- 1.4V-1.7Si 3.0TiC alloy is also increased. |
| Keywords: | spray-forming in-situ reaction high temperature aluminum alloy microstructure mechanical property |
