Development.Such as the creep analysis instrument of TA instrument companies of the U.S. (former du pont company's instrument portion).Its temperature measurement range is：One
150 DEG C to 1000 DEG C, maximum sample is highly:25mm, maximum sample is a diameter of：10mm, sensitivity is：100mn, displacement model
Enclose for：+/- 2.5mm, load range is：0.001~1.0 newton, test environment for static state, or using control flow inertia and
Reactant gas, prevents specimen surface from aoxidizing.
Method on being heated to material,《Current Heating method in light-alloy plate superplastic forming and its grand microcosmic
Analysis》In mention Current Heating method, magnesium alloy plate is heated to 400 DEG C in 1 point, ultrahigh in efficiency, but require
Current density is up to 27.5A/mm2, more than 1000 DEG C of temperature is reached, the requirement to wire is too harsh；《Aero-engine whirlpool
Impeller blade emissivity measurement》Middle use crucible electrical resistance furnace is heated to full wafer turbo blade, and maximum temperature reaches 800 DEG C, distance hair
1400 DEG C -1600 DEG C of motivation blade maximum operating temperature, in addition whole body of heater be inconvenient to transform, measurement high-temerature creep etc. is caused
Difficulty.
Existing heater can not meet the requirement of metal micro sample high temperature experiment, therefore, develop for metal
The small-sized heater of microspecimen high temperature experiment is significant.
