奥氏体半沉淀不锈钢箔片是一种新材料。箔片的厚度很薄,机械性能不仅在常温下较好,而且能耐高温。可用在航空结构和其他方面。因此,结构设计方面和强度理论方面都要求测定这种材料的机械性能。 我们采用悬臂梁强迫振动及扭摆的自由振动,分别测定0.05毫米与0.03毫米厚的箔片在常温及高温下的弹性模量,最高温度为500℃。500℃高温下测得的弹性模量与常
Austenitic semi-precipitated stainless steel foil is a new material. The thickness of the foil is very thin and the mechanical properties are not only good at room temperature but also high temperature. Available in aeronautical structures and other areas. Therefore, both structural design and strength theory require the determination of the mechanical properties of this material. We use the cantilever to force the vibration and torsional vibration free vibration, respectively, 0.05 mm and 0.03 mm thick foil at room temperature and high temperature modulus of elasticity, the maximum temperature is 500 ℃. Modulus of elasticity measured at 500 ° C
