摘要
以航空、航天用超硬铝合金7A04为研究对象,利用实验研究了多种瞬态热冲击环境下,温度对该材料力学性能的影响。结果表明,随着瞬态热冲击温度的升高,超硬铝合金7A04软化现象越发明显,塑性增加,材料的承载能力和承载截面积降低,发生断裂所需时间缩短。
Taking super duralumin alloy 7A04 used in aviation and spaceflight as research object, the influence of temperature on the mechanical properties of the material was studied by transient thermal shock experiment. The results show that with the increase of transient thermal shock temperature, the softening phenomenon of super duralumin alloy 7A04 more obvious, the plastic increases, the bearing capacity and bearing cross-sectional area of the materials reduce, and the time taking place fracture shorten.
