Abstract

The synergistic controlling of high densities, fine grain sizes, and low titanium-rich phase content is critical for high sputtering quality of W-Ti refractory alloy targets. In this work, high-performance W-Ti alloy targets have been successfully designed and prepared for the first time by using the dynamic sintering and forging (DSF) integrated method. Compared to hot press (HP) and hot oscillating pressing (HOP), DSF can achieve a relative density of 99.31 % for W-Ti alloys at a lower temperature of 1100 °C (more than 200 °C lower than the above methods). Moreover, its grain size was not grown abnormally and the formation of the Ti-rich phase was suppressed not to be observed. This had never been achieved in previous studies. The DSF integrated method preliminarily achieved the synergistic control of high densities, fine-grain sizes, and low titanium-rich phase content, which achievement provides a technical reference for the preparation of high-performance refractory alloy targets at low temperatures.

一种动态烧结-锻造一体化方法协同控制高密度、细晶、低富钛含量W-Ti耐火合金

高密度、细晶粒尺寸和低富钛相含量的协同控制是提高W-Ti耐火合金靶材溅射质量的关键。本文首次采用动态烧结与锻造（DSF）一体化方法成功地设计和制备了高性能钨钛合金靶材。与热压（HP）和热振荡压（HOP）相比，DSF在1100℃（比上述方法低200℃以上）的温度下可以使W-Ti合金的相对密度达到99.31%。晶粒尺寸没有异常增大，富ti相的形成受到抑制，未观察到。这在以前的研究中从未实现过。DSF综合方法初步实现了高密度、细晶粒尺寸和低富钛相含量的协同控制，为低温下制备高性能耐火合金靶材提供了技术参考。

期刊介绍： Results in Physics is an open access journal offering authors the opportunity to publish in all fundamental and interdisciplinary areas of physics, materials science, and applied physics. Papers of a theoretical, computational, and experimental nature are all welcome. Results in Physics accepts papers that are scientifically sound, technically correct and provide valuable new knowledge to the physics community. Topics such as three-dimensional flow and magnetohydrodynamics are not within the scope of Results in Physics. Results in Physics welcomes three types of papers: 1. Full research papers 2. Microarticles: very short papers, no longer than two pages. They may consist of a single, but well-described piece of information, such as: - Data and/or a plot plus a description - Description of a new method or instrumentation - Negative results - Concept or design study 3. Letters to the Editor: Letters discussing a recent article published in Results in Physics are welcome. These are objective, constructive, or educational critiques of papers published in Results in Physics. Accepted letters will be sent to the author of the original paper for a response. Each letter and response is published together. Letters should be received within 8 weeks of the article''s publication. They should not exceed 750 words of text and 10 references.
