Abstract对B4C质量分数分别为26%和31%的B4C/6061铝合金(6061Al)复合材料中子吸收板在高温(400℃)和装卸料模拟工况(硼酸水浸泡→去离子水清洗→高温干式运输过程)下进行老化试验,通过拉伸性能、尺寸、质量、密度等变化分析了其老化行为。结果表明:2种复合材料中子吸收板在高温老化过程中的性能稳定,尺寸、质量、密度、B4C含量及10B面密度均无明显变化,高温老化后375℃及室温拉伸性能随老化时间的延长未发生明显变化;模拟工况试验后矩形试样表面无明显的局部腐蚀现象,包覆试样表面局部腐蚀形成氧化膜,试验前后试样的厚度、质量、密度和10B面密度无明显变化。
Other AbstractAging tests under high temperature(400 ℃)and simulated loading and unloading(boric acid water soaking→deionized water cleaning→high temperature dry transportation process)conditions were conducted on B4C/6061 Al composite neutron absorber plates with B4C mass fractions of 26% and 31%,respectively.The aging behavior was analyzed by the change of tensile properties,size,mass,density,and so on.The results show that the performance of the two composite neutron absorber plates was stable during high temperature aging.The size,mass,density,B4C content and 10 B areal density had no significant changes during high temperature aging;after high temperature aging,the tensile properties at 375℃and room temperature did not change significantly with the aging time.After the simulated working test,no obvious local corrosion was observed on the surface of the rectangular sample;the surface of the encapsulated sample was locally corroded and oxide films were formed.The thickness,mass,density,and 10B areal density of the samples changed little before and after the test.
