采用FESEM、TEM、EBSD、拉伸实验和热暴露实验等方法研究了Al-AlN异构复合材料的微观组织、力学性能和热稳定性,分析了复合材料的热稳定性及其稳定机理。结果表明：Al-AlN复合材料的组织为由粒子富集区和粒子贫乏区交替分布形成的异质片层结构,粒子富集区的基体晶粒为超细晶结构,粒子贫乏区为粗晶结构；该复合材料在500℃长达100 h的热暴露条件下表现出优异的热稳定性,并且其热稳定性和抗拉强度的综合性能组合显著优于传统的耐热铝合金；分析认为其主要的热稳定机理是高温下晶界上的AlN纳米颗粒钉扎晶界,抑制了晶界迁移和晶粒长大,从而使该Al-AlN异构纳米复合材料在表现出优异的强度-塑性匹配的同时,还表现出良好的热稳定性。此外,在热暴露实验的初期,还发现了异常强化和硬化现象,且热暴露温度越高其强度和硬度提高的幅度越大,这主要与热处理过程中发生了晶界驰豫强化有关。

Efforts to develop high-strength and heat-resistant Al alloys have been ongoing to reduce the weight of automobiles and achieve transportation with low emissions. Traditional heat-resistant Al alloys are difficult to use at temperatures higher than 300oC because of the strength loss from precipitate coarsening behavior. This study examined the microstructure, mechanical properties, and thermal stability of a heterostructured Al nanocomposite reinforced by AlN nanoparticles using FESEM, TEM, EBSD, tensile test, and thermal exposure experiments. The heterogeneous lamellar structure of Al-AlN nanocomposite was composed of alternate distributed particle-rich and particle-free zones. Ultrafine Al grains formed in the particle-rich zone, whereas coarse Al grains formed in the particle-free zone. The mechanical tests of the Al-AlN nanocomposite showed no visible microhardness or loss of tensile strength after severe thermal exposure at 500oC for up to 100 h. The outstanding thermal stability and tensile strength combination were much better than the data in the literature. It is believed that the intergranular AlN nanoparticles pinned the Al grain boundaries and contributed to the superior thermal stability and strength. Furthermore, an abnormal increase in strength at the initial stage of the thermal exposure tests was revealed. A thermal exposure temperature resulted in a greater increase in strength and hardness, which was rationally interpreted in view of grain boundary relaxation strengthening.
