Description
Technical Field
The invention belongs to the technical field of structural characterization improvement of metal materials, and particularly relates to a preparation method of an electropolished titanium alloy large-size rod-shaped or plate-shaped sample.
Background
The high-strength and high-toughness titanium alloy has the characteristics of high specific strength, excellent corrosion resistance, fatigue damage resistance and the like, can meet the requirements of large-scale, high-speed and remote development of the design of an aerospace vehicle, and is widely applied to the field of aerospace. As an engineering structural member, the high-strength and high-toughness titanium alloy is inevitably subjected to complex and periodic stress action in the service process, so that the deformation damage, especially the fatigue damage of the alloy becomes a key factor for restricting the safety reliability and the long service life of the aircraft. Thereby causing the equipment and parts to be out of order or invalid, even causing serious safety accidents in serious conditions, and causing serious economic loss or casualties. Therefore, the deep research on the deformation damage mechanism of the titanium alloy is very important for providing an important theoretical basis for alloy design and structure optimization.
The In-situ SEM + EBSD In-situ stretching technology changes the traditional mode of the conventional macroscopic performance test, not only can directly observe the deformation and damage process of the material, but also can display the specific crystallographic orientation relationship, reveal more detailed problems In the material damage process and provide technical support for the organization unit deformation coordination mechanism, local strain concentration, damage formation and expansion of the high-strength and high-toughness titanium alloy consisting of the double plastic phases. However, the preparation of high quality EBSD tensile specimens is one of the challenges currently faced.
The common techniques for preparing EBSD samples today are mechanical polishing, vibratory polishing, argon ion beam polishing, and electropolishing. Mechanical polishing is because polishing paste hardness commonly used is big, and the granule is little, can the fish tail sample surface, and is unsmooth, has lost the roughness on surface to need constantly to wash by water in the polishing process, cause the oxidation easily, influenced the experimental effect. And secondly, vibration polishing and argon ion beam polishing, which can improve the quality of the EBSD sample to a certain extent, but have strict requirements on the size of the sample, generally the diameter of the sample is not more than 30mm, and the sample with larger size, such as a rod-shaped or plate-shaped sample with the length of more than 50mm, cannot be polished. The electrolytic polishing technology is a relatively common means, and different materials can be subjected to surface polishing treatment by changing the electrolytic polishing corrosive liquid. Currently, stainless steel is generally used for the cathode electrode of the titanium alloy in the electrolytic polishing process, because the stainless steel has excellent conductivity, the formation of a surface oxide film can be accelerated, but the polished area size is limited, and the EBSD sample with large size and high quality is difficult to obtain. If the cathode electrode material is changed into a pure titanium or titanium alloy material, the anode electrode connects the sample to be polished with the positive electrode of the power supply through pure titanium or titanium alloy tweezers, and compared with stainless steel, the conductivity of pure titanium or titanium alloy is poor, so that the risk of surface excessive oxidation is reduced, the area of a polishing area is increased, the electrolytic polishing of a large-size rod-shaped or plate-shaped tensile and fatigue sample can be realized at room temperature, and a high-quality surface with higher EBSD signal resolution rate is obtained.
