Test instrument for material mechanical properties at ultra-high temperature and high-temperature furnace used thereby

Abstract

The invention belongs to the field of material ultra-high temperature mechanical property testing, relates to a test instrument for material mechanical properties at ultra-high temperature, in particular to an instrument for measuring the mechanical performances (for example, indentation characteristics, hardness and the like) of an object to be tested under ultra-high temperature conditions, anda high-temperature furnace with a special structure used in the instrument. The high-temperature furnace comprises a furnace body, a furnace bottom and a furnace cover, wherein the furnace body is connected with the furnace cover in a dynamic sealing manner, the furnace body and the furnace bottom are welded and in machine-made leveling to be formed integrally. The test instrument for the materialmechanical properties at the ultra-high temperature comprises the high-temperature furnace, and further comprises a sample rotating component, a data acquiring-processing component, an automatic control component and a vacuum pumping component and / or a protective gas filling component. The test instrument for the material mechanical properties at the ultra-high temperature, disclosed by the invention, not only maintains vacuum or protective atmosphere in the high-temperature furnace to solve the problems of inconvenient operation and the like caused by that the hardness tester or indenter inthe prior art is integrally kept in the vacuum or protective atmosphere.

Description

technical field [0001] The invention belongs to the field of ultra-high temperature mechanical property testing of materials, and relates to an instrument for testing ultra-high temperature mechanical properties of materials, specifically an instrument for measuring the mechanical properties (such as indentation characteristics, hardness, etc.) of objects under ultra-high temperature conditions. And the special structure high temperature furnace used in this instrument. Background technique [0002] At present, all kinds of indentation instruments and hardness instruments mostly test the mechanical properties of the material surface at room temperature. However, in recent years, many materials need to work at ultra-high temperatures (for example: up to 1500°C), and the research on the ultra-high temperature mechanical properties of these materials is very important. The traditional testing methods for the mechanical properties of materials are difficult to meet the actual ne...
