Embodiment Construction

[0043] A method for visualization of alloy solidification synchrotron radiation imaging, comprising the following steps:

[0044] 1. Sample Preparation

[0045] (1) Preliminary sample preparation

[0046] a. Use a vacuum melting furnace to prepare an alloy with a certain composition, and pour it into a water-cooled copper mold to obtain an ingot;

[0047] b. The ingot sample is cut transversely into 1mm slices;

[0048] c. Use 502 glue to stick the thin slice sample on the stainless steel sample holder, and grind the front and back of the sample with 200#, 400#, 600#, 800# sandpaper, and finally make an ultra-thin sample with a thickness of 100-200μm;

[0049] d. Soak the sample with acetone solution to make the ultra-thin sample fall off the sample holder automatically, and perform ultrasonic cleaning in the acetone solution;

[0050] e. Cut the ultra-thin sample into 20×10mm 2 , and placed in the middle of a hollow mica sheet with a thickness of 100 μm, and then sandwich...

Abstract

The invention relates to an alloy solidification synchrotron radiation imaging visualization method, wherein a small temperature gradient furnace which is used for synchrotron radiation X-ray imaging is used for heating, the heating temperature can be 800-1000 DEG C. The method comprises the following steps of: sample preparation, preparation for applying an electric field; preparation for applying a magnetic field; assembling of an integral imaging device; and visualization measurement of alloy solidification synchrotron radiation imaging, and particularly comprises high-temperature anti-oxidation treatment of samples and selection and introduction of electrodes. According to the invention, the method overcomes the limit that the existing heating furnace for alloy solidification synchrotron radiation imaging can only be used for heating alloy with low melting point, and can be applied to different alloys widely, in particular to research of solidification synchrotron radiation imaging visualization of alloy with medium-high melting point, and the method has significant meaning in understanding and perfecting microcosmic alloy growth academically, in industrial optimization of a solidification organization control project and in improving mechanics and physical properties of metal materials effectively.

Description

technical field [0001] The invention relates to basic research in the solidification process of alloys, in particular to a synchrotron radiation imaging visualization method for solidification of alloys. Background technique [0002] The inherent opacity of metal alloys and the high-temperature environment during solidification restrict researchers from carrying out experimental dynamic observations on alloys. It is difficult for researchers to directly observe how the solidification process of opaque alloys at high temperatures proceeds. Basic research on the solidification process, such as the regulation and mechanism of solidification conditions, alloy composition, external physical fields, etc.; to further understand / perfect the microscopic growth theory of metal alloys in the academic field; to optimize the solidification structure control engineering in industry and effectively improve The mechanical and physical properties of metal materials are of great significance....
