Problems solved by technology

[0004] Ti 2 The degree of AlNb alloying is high, and the content of Al and Nb exceeds 20% (at.%); the change of the phase region leads to significant changes in the microstructure and mechanical properties of the material. Therefore, for the powder particles themselves, the preparation of powder EBSD samples and Subsequent detection and characterization is of great significance. 2 Public reports on the EBSD sample preparation method of AlNb alloy powder are very rare, therefore, designing a Ti 2 EBSD sample preparation method of AlNb alloy powder is very necessary

Embodiment 1

[0036] Use 60 mesh standard sieve to sieve Ti 2 AlNb powder for fine and uniform Ti 2 AlNb powder. Mix 4221 reagent, 736 reagent, NSA reagent and DMAE reagent at 100:80:250:3 (mass ratio) to obtain Spurt low-viscosity resin embedding agent with good ratio. Use a standard measuring vessel to measure Ti at a certain volume ratio 2 Proportioning of AlNb alloy powder and Spurt low viscosity resin embedding agent, Ti 2 AlNb alloy powder / Spurt low viscosity resin embedding agent=1 / 6 (volume ratio). Will match the good Ti 2 Put AlNb alloy powder / low viscosity Spurr embedding set into a Ti-6Al-4V crucible with an outer diameter of 10mm, a wall thickness of 2mm, and a height of 5mm, and stir evenly for 10min to make Ti 2 The AlNb alloy powder / Spurt low-viscosity resin embedding agent is fully and uniformly mixed, and then the crucible is placed in an oven, and is cured at 70°C for about 10 hours to obtain a mosaic sample. On the metallographic grinder, 2000# and 5000# water sandp...

Abstract

The invention discloses a preparation method of an EBSD sample of Ti2AlNb alloy powder, and belongs to the technical field of powder metallurgy titanium alloy processing. The method comprises the following steps: firstly, pouring a low-viscosity Surr embedding set and Ti2AlNb powder into a Ti-6Al-4V crucible, and uniformly mixing the low-viscosity Surr embedding set and the Ti2AlNb powder; then curing a mixture at 70 DEG C for 10 hours; and sequentially carrying out grinding and mechanical polishing, and then carrying out ion bombardment, cleaning and blow-drying to obtain the EBSD sample of the Ti2AlNb alloy powder. The method is simple, convenient and flexible to operate, high in EBSD experiment success rate, easy to popularize and wide in application prospect.

Description

technical field [0001] The invention relates to the technical field of powder metallurgy titanium alloy processing, in particular to a Ti 2 EBSD sample preparation method of AlNb alloy powder. Background technique [0002] Since the 1990s, the analysis technology of electron backscattering patterns (EBSP) crystal micro-region orientation and crystal structure based on scanning electron microscopy has made great progress, and has been used in the microstructure and microstructure of materials. Widely used in texture characterization. This technology is also known as electron backscattered diffraction technology, the English name is Electron Backscattered Diffraction, referred to as EBSD. data). EBSD has changed the previous method of texture analysis and formed a new scientific field called "microtexture" - combining microstructure and crystallographic analysis. Closely related to "microtexture" is the application of EBSD for phase analysis, obtaining interface (grain bou...
