内容简介

The Young’s modulus was measured at high temperatures by impulse excitation of vibration method, and the effects of heating rate, holding time and temperature cycle on the test results were analyzed. The results show that the heating rate has obvious effect on the high temperature Young’s modulus of the green body, but has no obvious effect on that of the sintered products; the holding time of the heating process has no regular effect on the Young’s modulus, and the effect varies with the different products at a certain temperature; the method can also be used to test the Young’s modulus during cooling process.
