研究了纳米结构Al基体中B4 C颗粒尺寸（微米级和纳米级）对热处理过程中组织演变和力学性能的影响。结果表明，纳米B_4C的加入能显著抑制铝在热处理过程中的晶粒长大。热处理后，Al/B4 C复合材料界面偏析层增多。在所有试样的晶内均观察到高密度的GP区和片状η'相，而在AA 7075合金和微B_4C复合材料的晶界处观察到粗大的η相（MgZn_2）。加入纳米B4 C的复合材料热处理后的屈服强度可达958 ± 28 MPa，这主要归因于Hall-Petch强化和位错强化。
We reported the influence of particle size (micro-B4C and nano-B4C) on microstructural evolution and mechanical properties in nanostructured Al matrix during heat treatment. The results indicated the incorporation of nano-B4C could significantly inhibit the grain growth of Al during heat treatment. The segregation layer in Al/B4C interface increased after heat treatment for all the composites samples. High density of Guinier-Preston (GP) zones and platelet η' could be observed in grain interior of all samples, while some coarse η phases (MgZn2) could be only detected in grain boundaries of AA7075 alloys and the composites with micro-B4C. The yield strength of the composites with the incorporation of nano-B4C could reach up to 958 ± 28 MPa after heat treatment, which could be ascribed to the Hall-Petch strengthening and dislocation strengthening.
