Problems solved by technology

However, the existing sample boxes basically have interference signal peaks contributing to the detected sample data, which will affect the data analysis, so that the microstructure and dynamic mechanism of the test sample cannot be accurately reflected and analyzed.
This largely inhibits the promotion and application of neutron scattering technology

Embodiment

[0017] The material used to prepare the sample box for neutron scattering experiments in this example is Ti 2.083 Zr, its preparation method is as follows:

[0018] 99.71g of titanium metal powder and 91g of zirconium metal powder were weighed, mixed evenly, and smelted into rods to obtain the titanium-zirconium alloy material used to prepare the neutron scattering experiment sample box in this example.

[0019] The Ti prepared in this example 2.083 The Zr material is prepared into a sample box of a suitable size according to the specific use requirements.

[0020] According to the neutron scattering length and cross-section data released by the National Institute of Standards and Technology, the titanium-zirconium alloy Ti prepared in this example is calculated 2.083 Zr, the sample box prepared by it, the neutron coherent scattering length is zero. Using the Monte Carlo simulation software Vitess, simulate and calculate the scattering spectrum when the coherent scattering ...

Abstract

The invention discloses a zirconium-titanium alloy for preparing a non-magnetic sample box for neutron scattering experiments and application of the zirconium-titanium alloy. The general formula of the zirconium-titanium alloy for preparing the non-magnetic sample box for neutron scattering experiments is TixZry, wherein the atomicity ratio of titanium to zirconium, namely, x:y is (2.08+ / -0.1):1. According to the zirconium-titanium alloy material, the zirconium-titanium alloy with the atomicity ratio of titanium to zirconium being (2.08+ / -0.1):1, especially, the zirconium-titanium alloy Ti2.083Zr is adopted, so that the prepared sample box hardly generates interference signal peaks in detected test sample data, and thus the data quality of neutron scattering experiments is more reliable and more credible. Meanwhile, the material is high in strength, nonmagnetic and capable of being produced in batches and widely applied to neutron scattering experiments, especially, experiments with a high magnetism control requirement, and a foundation is laid for application and popularization of the neutron scattering technology.

Description

technical field [0001] The present application relates to the field of auxiliary tools for neutron scattering experiments, in particular to a titanium-zirconium alloy for preparing a non-magnetic sample box for neutron scattering experiments and its application. Background technique [0002] Due to the unique advantages of neutrons such as uncharged, penetrating, magnetic moment, sensitive to light elements, and able to distinguish isotopes and adjacent elements, neutron scattering technology is widely used in physics, chemistry, new energy, life, medicine, materials, It plays an irreplaceable role in scientific research and industrial applications such as engineering and national security. [0003] In the neutron scattering experiment, the test sample can be in the form of liquid, powder and solid. Most of the samples need to be contained and packaged in a sample box, and then the sample box is placed on the sample stage. During the experiment, the neutron beam is incident ...
