摘要
叙述了以采用钨链作为悬挂元件,压电换能器作为试样共振的激发和接收器件的悬挂共振法。测定了钨和820石墨室温～2000℃的弹性常数E、G、μ,并将测试结果与文献值进行了此较,二者符合较好。
This paper describes the suspension resonance method in which the tungsten chain is used as the suspension elements and the piezoelectric transducers as exciting and receiveing device of specimen resonance. Elastic constants E,G,μ of tungsten 820-graphite are determined from room temperature to 2000℃ and the results are compared with reference data,both of them are well agreed.
