Embodiment 1

[0026] A method for preparing pure titanium EBSD sample at room temperature, comprising the following steps:

[0027] a. Grinding the surface to be tested of the pure titanium sample: use 150#, 320#, 600# and 1000# SiC sandpaper to perform cross grinding on the surface to be tested of the pure titanium sample, and rinse with water continuously during the grinding process surface, in order to remove the abrasive sticking to the surface of the sample, each time when changing a piece of sandpaper, the sample should be rotated 90° before grinding, and all the grinding marks left by the previous piece of sandpaper should be removed, during the grinding process During the process, the sample should be uniformly stressed and the surface should be flat; after polishing, the surface of the sample should be rinsed with absolute ethanol, and the surface of the sample should be air-dried under the action of natural wind.

[0028] b. Perform electropolishing treatment on the surface to be ...

Embodiment 2

[0033] A method for preparing pure titanium EBSD sample at room temperature, comprising the following steps:

[0034] a. Grinding the surface to be tested of the pure titanium sample: use 150#, 320#, 600# and 1000# SiC sandpaper to perform cross grinding on the surface to be tested of the pure titanium sample, and rinse with water continuously during the grinding process surface, in order to remove the abrasive sticking to the surface of the sample, each time when changing a piece of sandpaper, the sample should be rotated 90° before grinding, and all the grinding marks left by the previous piece of sandpaper should be removed, during the grinding process During the process, it is necessary to keep the sample under uniform force and the surface is smooth; after grinding, rinse the surface of the sample with absolute ethanol, and let the surface of the sample be air-dried under the action of natural wind;

Abstract

The invention relates to the field of metallic material analysis sample preparation technologies and particularly discloses a method of preparing a pure titanium EBSD sample under room temperature. According to the method, a to-be-tested surface of a pure titanium sample is subjected to polishing, electrolytic polishing and titanium corrosion treatment sequentially, and the pure titanium EBSD sample is obtained. The method of preparing the pure titanium EBSD sample is easy to operate and low in preparation cost and has a low requirement on environmental conditions, and the obtained pure titanium EBSD sample has a high calibration rate.

Description

technical field [0001] The invention relates to the technical field of preparation of metal material analysis samples, in particular to a method for preparing pure titanium EBSD samples at room temperature. Background technique [0002] Titanium is a new metal with great national defense significance and significant economic benefits in the field of contemporary high-tech new materials. It has the reputation of "the third metal" and "all-round metal". It has high strength and toughness, low density, high specific strength and corrosion resistance. It is widely used in defense industries such as aviation, aerospace, nuclear energy, and ships, as well as civilian industries such as chemical industry, petroleum, metallurgy, transportation, marine, and medical treatment. Electron Backscattered Diffraction (EBSD) analysis is an important analytical technique for studying the internal structure of polycrystalline materials and improving the physical properties of materials. The E...
