specific Embodiment

[0023] In order to further clarify the technical advantages of the present disclosure, it will be described in detail in conjunction with the examples, the specific examples are as follows:

[0024] The clamp of the present disclosure includes: a chuck bolt 1, a chuck body 2, and a sample fixing assembly; wherein the chuck bolt 1 is fixed on the chuck body 2 through threaded connection, the chuck body 2 is provided with a trapezoidal opening, and the trapezoidal opening The upper bottom edge of the trapezoid faces outward, thus presenting a trapezoidal opening with a large inside and a small outside; the trapezoidal slope opening is used in the chuck body, and it is locked with the left and right fixed wedge clamps; and the greater the pulling force, the left and right The greater the horizontal thrust of the fixed wedge-shaped clamps 5 and 3, the greater the horizontal thrust, the greater the horizontal pressure on the sample, so that the test fixture clamps the test sample mo...

Abstract

The invention belongs to the field of neutron scattering experiments and especially relates to a dedicated clamp for a neutron small-angle scattering high-temperature in-site tensile test. The clamp comprises a clamp head bolt, a clamp head body and a sample fixing assembly, wherein the clamping head bolt is connected with a tensile testing machine pull rod, the clamping head bolt is fixedly connected to the clamping head body, and the clamping head body can provide axial tension for the sample fixing assembly. Therefore, the dedicated clamp for the neutron small-angle scattering high-temperature in-site tensile test disclosed by the invention has the advantages of convenience in assembling and disassembling and firmness in clamping.

Description

technical field [0001] The disclosure belongs to the field of neutron scattering, in particular to a special fixture for neutron small-angle scattering high-temperature in-situ tensile test. Background technique [0002] Small-angle neutron scattering is an experimental technique that uses elastic neutron scattering at low scattering angles to study the internal mesoscopic structure of different substances. Through the sample environment of applying thermal field and force field at the same time, in-situ observation of microstructure changes inside the material can be carried out, and the heat treatment process and creep mechanism of the material can be studied. In the small-angle neutron scattering high-temperature in-situ stretching device, the furnace of the high-temperature furnace is small, and larger samples and larger clamping fixtures are not allowed. No additional non-axial force etc. In order to meet the requirements of the small-angle neutron scattering experime...
