Ultrahigh-temperature laser confocal microscope compression sample and manufacturing method thereof

The invention discloses an ultra-high temperature laser confocal microscope compression sample and a manufacturing method thereof, and mainly relates to a dumbbell-shaped sample in an ultra-high temperature laser confocal microscope compression test, and the sample is composed of a clamping part and an effective deformation part. The dumbbell-shaped sample is made of a test material and sequentially subjected to saw cutting through a full-automatic metal band saw, turning through a precision lathe and machining cutting through an electric spark numerical control linear cutting machine tool, after rough machining preparation of the compressed sample is completed, the sample obtained after rough machining is completed is placed into a clamp for high-finish-degree treatment of the deformed part of the dumbbell-shaped sample to be further machined, and the dumbbell-shaped sample is obtained. Then a handheld portable metallographic grinding and polishing machine is used for conducting rough grinding of a grinding
