Abstract

Tungsten‑rhenium (W-Re) alloys are extensively used in medical devices, electronics, industrial equipment, aerospace, and nuclear energy sectors due to their low ductile-to-brittle transition temperature (DBTT), excellent high-temperature creep resistance, and superior properties related to recrystallization, ablation, and irradiation at elevated temperatures. However, with the advancement of technologies in these critical fields, the performance demands on W-Re alloys are continually increasing. As a result, optimizing the fabrication processes of W-Re alloys to enhance their performance under ultra-high temperature conditions has become essential. This review provides a detailed overview of the ultra-high temperature applications of W-Re alloys, the effects of Re alloying on their performance, various strengthening methods and mechanisms, and fabrication techniques. By analyzing the strengthening mechanisms, we identify that advancements in powder preparation, bulk densification, and deformation processing are key to improving the stable performance of W-Re alloys under extreme temperatures. Additionally, we address several challenges related to the fabrication methods and propose solutions. We hope that this comprehensive review will support researchers in developing W-Re alloys with enhanced performance while addressing the production and engineering challenges involved.

耐超高温钨铼合金的制备及性能研究

钨铼（W-Re）合金由于其低韧脆转变温度（DBTT）、优异的高温抗蠕变性能以及在高温下的再结晶、烧蚀和辐照等优越性能，广泛应用于医疗器械、电子、工业设备、航空航天和核能领域。然而，随着这些关键领域技术的进步，对W-Re合金的性能要求也在不断提高。因此，优化W-Re合金的制备工艺以提高其在超高温条件下的性能变得至关重要。本文综述了W-Re合金的超高温应用、Re合金化对其性能的影响、各种强化方法和机理以及制备技术。通过分析强化机理，我们发现粉末制备、体致密化和变形处理的进步是提高W-Re合金在极端温度下稳定性能的关键。此外，我们解决了与制造方法相关的几个挑战，并提出了解决方案。我们希望这篇全面的综述将支持研究人员开发具有增强性能的W-Re合金，同时解决所涉及的生产和工程挑战。

期刊介绍： The International Journal of Refractory Metals and Hard Materials (IJRMHM) publishes original research articles concerned with all aspects of refractory metals and hard materials. Refractory metals are defined as metals with melting points higher than 1800 °C. These are tungsten, molybdenum, chromium, tantalum, niobium, hafnium, and rhenium, as well as many compounds and alloys based thereupon. Hard materials that are included in the scope of this journal are defined as materials with hardness values higher than 1000 kg/mm2, primarily intended for applications as manufacturing tools or wear resistant components in mechanical systems. Thus they encompass carbides, nitrides and borides of metals, and related compounds. A special focus of this journal is put on the family of hardmetals, which is also known as cemented tungsten carbide, and cermets which are based on titanium carbide and carbonitrides with or without a metal binder. Ceramics and superhard materials including diamond and cubic boron nitride may also be accepted provided the subject material is presented as hard materials as defined above.
