引言 現代动力机械制造中力求提高热效率的趋势,促使我們不断地提高机組的工作温度。但在新型的超高溫透平制造中,找寻一种既有足够的耐热性、塑性和抗腐蚀性,又有很高的減振性的叶片材料,则是生产上遇到的一項主要問題。因此探討一下減振性的物理意义、测定方法和各种因素对它的影响,无論对研究高溫材料
Introduction The modern dynamic machinery manufacturing efforts to improve the thermal efficiency of the trend, prompting us to continuously improve the operating temperature of the unit. However, in the manufacture of a new type of ultra-high temperature turbine, finding a blade material that has sufficient heat resistance, plasticity and corrosion resistance as well as high vibration damping properties is one of the main production problems encountered problem. Therefore, to explore the physical meaning of vibration damping, measuring methods and various factors on its impact, both for the study of high temperature materials
