Tungsten is a metal with many unique characteristics, such as a high melting point, high hardness, high chemical stability, etc. It is widely used in high-end manufacturing, new energy, the defense industry, and other fields. However, tungsten also has room-temperature brittleness, recrystallization brittleness, and other shortcomings due to the adjustment of the composition and organizational structure, such as the addition of alloying elements, adjusting the phase ratio, the use of heat treatment and deformation strengthening, etc. Its performance can be improved to meet the requirements for use in different fields. At present, the main production method of tungsten alloy is powder metallurgy. The use of a rolling open billet rotary forging–stretching process can improve production efficiency and product quality, but in actual production, due to the combined effects of various factors, such as elastic deformation of rolling elements, plastic deformation of the rolled material, etc., the mechanical properties of tungsten plates and bars are often difficult to control effectively, seriously affecting rolling stability and production efficiency. For this reason, researchers have conducted extensive and deep research and optimization on the rolling process of tungsten alloys, including establishing mathematical models, performing numerical simulations, optimizing process parameters, etc., providing important references for the rolling and forming of tungsten alloys. Meanwhile, the material properties are greatly influenced by the microstructure, and the evolution of the microstructure can be well quantified by some advanced characterization techniques, such as SEM, TEM, EBSD, etc., so that certain properties of tungsten can be obtained by controlling the texture evolution. In conclusion, this paper comprehensively summarizes the research progress of tungsten alloy roll forming and provides an important reference for further improving the processing performance and production efficiency of tungsten alloy.

钨合金滚压成形研究进展


钨是一种具有许多独特特性的金属，如高熔点、高硬度、高化学稳定性等，广泛应用于高端制造、新能源、国防工业等领域。但由于成分和组织结构的调整，如添加合金元素、调整相比、采用热处理和形变强化等，钨也存在室温脆性、再结晶脆性等缺点。其性能可进一步提高，以满足不同领域的使用要求。目前，钨合金的主要生产方法是粉末冶金法。采用轧制开坯旋锻-拉伸工艺可以提高生产效率和产品质量，但在实际生产中，由于滚动体弹性变形、轧制材料塑性变形等多种因素的综合影响， ..，钨板、棒材的机械性能往往难以有效控制，严重影响轧制稳定性和生产效率。为此，研究人员对钨合金轧制工艺进行了广泛而深入的研究和优化，包括建立数学模型、进行数值模拟、优化工艺参数等，为钨合金轧制成形提供重要参考。同时，材料性能受微观结构的影响很大，通过一些先进的表征技术，如SEM、TEM、EBSD等可以很好地量化微观结构的演变，从而通过控制钨的某些性能来获得钨的某些性能。纹理的演变。 综上所述，本文全面总结了钨合金滚压成形的研究进展，为进一步提高钨合金的加工性能和生产效率提供了重要参考。
