Abstract

Young’s modulus for heterophase composite silicon carbide ceramics with different phase ratios has been determined by two independent techniques. The applicability of the Voigt–Reuss–Hill model has been tested to the calculation of the effective Young’s modulus by the measured properties of ceramic components. It is established that the calculated data and results of independent measurements by dynamic indentation are close. It is shown that the advantage of the calculation method is a narrower range of the obtained values of Young’s modulus. At the same time, its application requires additional measurements of ceramic composition and mechanical properties of the components.

SiC基复合陶瓷弹性模量的确定

摘要

已经通过两种独立的技术确定了具有不同相比的异相复合碳化硅陶瓷的杨氏模量。Voigt-Reuss-Hill模型的适用性已通过测量陶瓷组件的性能进行了计算有效杨氏模量的测试。已经确定，通过动态压痕计算的数据和独立测量的结果是接近的。结果表明，该计算方法的优点在于所获得的杨氏模量值的范围较窄。同时，其应用需要对陶瓷成分和部件的机械性能进行额外的测量。
