Abstract

The mechanical behavior and cracking patterns of thermally‐shocked additively manufactured alumina were investigated. The flexural strength of test specimens that had been heated to temperatures ranging from 200°C to 1000°C and then rapidly quenched in water was determined at ambient temperature by four‐point bending. Results indicated that the surface cracking patterns had a multifractal structure and that an increase in the thermal shock temperature led to an increase in the density and uniformity of the crack network. The flexural strength results were analyzed with Weibull statistics, where the Weibull moduli for most of the thermal shock conditions tested were found to be statistically indistinguishable. It was also found that a significant decrease (∼50%) in flexural strength occurred for heating temperatures ≥300°C. The effect of the manufacturing method on cracking patterns is discussed, as well as the implication of the material behavior for practical applications of these materials.

加成型氧化铝的抗热震性
研究了热冲击添加剂制造的氧化铝的机械行为和裂纹模式。在环境温度下,通过四点弯曲法测定了加热至 200°C 至 1000°C 的试样在水中快速淬火后的抗弯强度。结果表明,表面裂纹具有多分形结构,热冲击温度的升高导致裂纹网络的密度和均匀性增加。用 Weibull 统计法分析了抗弯强度结果,发现大多数热冲击条件下的 Weibull 模量在统计上没有区别。研究还发现,加热温度≥300°C 时,抗弯强度显著下降(∼50%)。讨论了制造方法对开裂模式的影响,以及材料行为对这些材料实际应用的影响。
