Despite the sufficient exploration of industrial methods for the manufacturing of products from metal hafnium, the public domain has a limited number of reports that highlight the technological aspects of hafnium wire manufacturing and their effect on the structure and mechanical properties of the products formed [1, 2]. This article describes the methods employed in the manufacturing of hafnium wire from the ingots of its own production, which have been tested by Chepetsk Mechanical Plant (CMP) under industrial conditions, as well as the advantages and disadvantages of each tested method for producing the wire. The stages of hafnium wire drawing are described in detail. During the experiments, the relationships between the technological, energy–power parameters, surface quality, and material structure were studied. The effects of the type of drawing tool on the wire surface quality and drawing force were revealed, as well as the effects of the wire diameter on the amount of permissible deformation between the annealed products and the grain size of the metal. The paper reports the results of studies conducted on the structure, mechanical, and corrosion properties of the experimental samples of wires manufactured in compliance with the ASTM B737 standard specification for hot rolled and/or cold-drawn hafnium rods and wire. Currently, CMP can manufacture wires with a diameter of 1 mm or more from hafnium ingots of its own production, in compliance with the ASTM B737 standard.

符合 ASTM B737 标准的铪线生产的发展

尽管对用金属铪制造产品的工业方法进行了充分探索，但公共领域的报告数量有限，这些报告强调了铪线制造的技术方面及其对所形成产品的结构和机械性能的影响 [1, 2]。本文介绍了用自己生产的锭制造铪线所采用的方法，这些方法已经过 Chepetsk 机械厂 (CMP) 在工业条件下的测试，以及每种测试方法的优缺点。 . 详细描述了铪拉丝的各个阶段。在实验过程中，研究了工艺、能量-功率参数、表面质量和材料结构之间的关系。揭示了拉拔工具类型对线材表面质量和拉拔力的影响，以及线材直径对退火产品之间允许变形量和金属晶粒尺寸的影响。该论文报告了对按照 ASTM B737 热轧和/或冷拔铪棒和线材标准规范制造的线材实验样品的结构、机械和腐蚀特性进行的研究结果。目前，CMP 可以使用自己生产的铪锭制造直径为 1 毫米或更大的线材，符合 ASTM B737 标准。以及线径对退火产品之间允许变形量和金属晶粒尺寸的影响。该论文报告了对按照 ASTM B737 热轧和/或冷拔铪棒和线材标准规范制造的线材实验样品的结构、机械和腐蚀特性进行的研究结果。目前，CMP 可以使用自己生产的铪锭制造直径为 1 毫米或更大的线材，符合 ASTM B737 标准。以及线径对退火产品之间允许变形量和金属晶粒尺寸的影响。该论文报告了对按照 ASTM B737 热轧和/或冷拔铪棒和线材标准规范制造的线材实验样品的结构、机械和腐蚀特性进行的研究结果。目前，CMP 可以使用自己生产的铪锭制造直径为 1 毫米或更大的线材，符合 ASTM B737 标准。根据 ASTM B737 热轧和/或冷拉铪棒和线材的标准规范制造的线材实验样品的腐蚀性能。目前，CMP 可以使用自己生产的铪锭制造直径为 1 毫米或更大的线材，符合 ASTM B737 标准。根据 ASTM B737 热轧和/或冷拉铪棒和线材的标准规范制造的线材实验样品的腐蚀性能。目前，CMP 可以使用自己生产的铪锭制造直径为 1 毫米或更大的线材，符合 ASTM B737 标准。
