[0023] Si-ZrBr 2 High Temperature Uniaxial Tensile Test of Ceramics

[0024] First, measure the dimensions of the test piece. Use an electronic vernier caliper to measure the width of the specimen, measure the widths at both ends and the middle of the gauge section respectively, and then take the average value as the width of the gauge section of the specimen; use the same method to measure the height of the specimen. The cross-sectional area of ​​the test piece is equal to the product of the average width and the average thickness of the gauge length section.

[0025] Then place the test piece, adjust the positions of the induction coil and the test piece, and ensure that the central axis of the test piece, the axis of the induction coil and the axis of the stretching rod coincide with each other.

[0026] Turn on the dual colorimetric temperature measurement system, adjust the position and distance of the temperature measurement probe so that the probe is facing the center...

Abstract

The invention discloses a device for testing the uniaxial tension mechanical property of a conducting material under high temperature environment, and belongs to the technical field of material mechanical property testing. According to the device, an induction coil is wound by a copper pipe; an upper insulating tension bar is connected with the upper end surface of an upper clamp through an upper insulating spacer; a lower insulating tension bar is connected with the lower end surface of a lower clamp through a lower insulating spacer; when the upper end of a test piece to be tested is clamped at the lower end of the upper clamp, and the lower end of the test piece to be tested is clamped at the upper end of the lower clamp, the induction coil sleeves the outer side of the test piece to be tested at intervals, and the two ends of the induction coil are respectively connected with two high-frequency driving output ends of an induction heating system controller; the temperature testing end of a temperature testing probe remotely tests the temperature of the test piece to be tested; the temperature signal output end of the temperature testing probe is connected with the temperature signal input end of the induction heating system controller. The device adopts induction heating, is small in size of the induction coil, simple to manufacture, is connected with the heating system controller through a bolt, and is convenient to disassemble and relatively quick in temperature rise.

Description

technical field [0001] The invention belongs to the technical field of material mechanical performance testing. Background technique [0002] At present, in the normal temperature environment, the test equipment and test plan for the uniaxial tension of materials are quite mature. For metal materials, a unified national standard "Test Method for Tensile Test of Metal Materials at Room Temperature" (National Standard: GB / T 228-2002 ); but in some special environments, such as rocket engines, the surface of hypersonic vehicles, and structures in this environment, they often withstand the test of a long-term high-temperature environment. In this environment, the mechanical properties of the material play a critical role in the longevity and reliability of the structure. The uniaxial tensile test of materials under high temperature environment is an important means to characterize the high temperature mechanical properties of materials. Therefore, it is essential to study and ...
