Abstract

In the aeronautical field, materials are used in severe environmental conditions (temperature, atmosphere), particularly for engine applications. In order to qualify new alloys compositions, ONERA is developing micromechanical characterization means to carry out indentation tests from room temperature up to 700 °C under conditions close to operating conditions. This method presents the interest of performing tests faster than classical mechanical tests like tensile or bending tests under severe conditions and with small amounts of materials. In order to carry out screening tests, a 316L stainless steel is studied and the evolution of hot Vickers hardness properties and yield stress versus temperature are presented. By increasing the applied load from 0.1 to 20 N, we show that we can neglect surface microstructural changes or possible contamination of the sample surface by oxidation. We show that from 0.5 N, the hardness measurement is independent of load on 316L stainless steel. By using Tabor’s law to express the mechanical resistance, we show that the hardness decreases by 50% when the test temperature goes from 20 to 700 °C, which is close to the supplier’s values. A discussion on the use of indentation to determine mechanical resistance and the limitations of this technique is presented. In perspective, these measurements could be carried out at 1000 °C and on many different materials such as layers, coatings, composite materials, brazing cords or additive manufacturing materials.

采用高温显微硬度计测定不锈钢的力学性能
在航空领域,材料在恶劣的环境条件下使用(温度,大气),特别是发动机应用。为了鉴定新的合金成分,ONERA正在开发微力学表征手段,以便在接近操作条件的条件下,从室温到700°C进行压痕测试。这种方法比传统的机械测试(如在恶劣条件下使用少量材料的拉伸或弯曲测试)更快地进行测试。为了进行筛选试验,研究了316L不锈钢的热维氏硬度性能和屈服应力随温度的变化规律。通过将施加的载荷从0.1 N增加到20 N,我们表明我们可以忽略表面微观结构的变化或样品表面可能被氧化污染。结果表明,从0.5 N开始,316L不锈钢的硬度测量与载荷无关。通过Tabor定律来表示机械阻力,我们发现当测试温度从20°C到700°C时,硬度降低了50%,与供应商的值接近。讨论了压痕法测定机械阻力的方法及其局限性。从角度来看,这些测量可以在1000°C和许多不同的材料上进行,例如层,涂层,复合材料,钎焊线或增材制造材料。
