INTERNATIONAL JOURNAL OF REFRACTORY METALS & HARD MATERIALS

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.The journal seeks contributions that investigate novel alloy design concepts; studies of the relationships between chemical composition, microstructure, and properties; novel methods of characterization and testing, novel methods of synthesis and processing, especially those that result in improved or novel microstructures, leading in turn to improved properties and novel applications. Articles focus on methods and processes that reduce material and energy consumption, hence the cost of these materials will also be considered.The process technologies may include but are not limited to powder synthesis and production technologies (chemical methods, physical methods such as mechanical ball milling); powder compaction and shaping technologies including die compaction, powder injection molding, and 3D printing; and sintering and consolidation processes such as vacuum sintering, hot isostatic pressing, field assisted sintering, and other advanced hot consolidation techniques. However, manuscripts that focus on processes without a clear explanation on how the process can lead to improved microstructure and properties, or reduction of energy consumption and costs are likely discouraged.This journal also publishes articles dealing with the deposition process and the microstructure and the measurement of selected properties of coatings, provided the coating consists of a material from the groups defined above, and is applied on the surface of a refractory metal or hard material. For eligibility of such articles the material science aspect of the coatings and if applicable their interrelationship with the properties of the coatings is of prime importance. Papers lacking this focus are usually referred to other journals dedicated to surface coating or machining.IJRMHM aims to bridge the gap between pure research and the more practical aspects of production and properties. In that IJMHM will continue to provide a medium linking together material scientists, engineers, designers and manufacturers working in this field.

INTERNATIONAL JOURNAL OF REFRACTORY METALS & HARD MATERIALS期刊中文简介

国际难熔金属与硬材料杂志(IJRMHM)发表了有关难熔金属与硬材料各方面的原创研究文章。难熔金属是指熔点大于1800℃的金属。它们是钨、钼、铬、钽、铌、铪和铼，以及以此为基础的许多化合物和合金。本杂志范围内的硬材料定义为硬度值大于1000 kg/mm2的材料，主要用于制造工具或机械系统中的耐磨部件。因此，它们包括金属的碳化物、氮化物和硼化物以及相关化合物。本杂志特别关注硬质合金系列，也被称为硬质合金钨，以及基于碳化钛和碳氮化物的金属陶瓷，无论有没有金属粘结剂。陶瓷和超硬材料，包括金刚石和立方氮化硼也可以接受，只要主题材料是上述定义的硬材料。该杂志寻求研究新的合金设计概念的贡献；化学成分、微观结构和性能之间关系的研究；新颖的表征和测试方法，新颖的合成和加工方法，特别是那些导致改进或新颖的微观结构的方法，从而改进性能和新颖的应用。文章的重点是方法和过程，以减少材料和能源消耗，因此这些材料的成本也将被考虑。工艺技术可以包括但不限于粉末合成和生产技术(化学方法、物理方法如机械球磨)；粉末压实成型技术，包括模具压实、粉末注射成型、3D打印；以及烧结固结工艺如真空烧结、热等静压烧结、现场辅助烧结等先进的热固结技术。然而，那些只关注过程而没有明确说明过程如何能改善微观结构和性能，或减少能源消耗和成本的手稿可能会受到劝阻。如果涂层由上述定义的一种材料组成，并应用于难熔金属或硬材料的表面，本杂志还发表有关沉积过程、涂层的微观结构和选定性能的测量的文章。对于这些产品的合格性，涂层的材料科学方面以及如果适用，它们与涂层性能的相互关系是最重要的。缺乏这一重点的论文通常被引用到其他致力于表面涂层或机械加工的期刊上。IJRMHM旨在填补纯研究与生产和性能的更实际方面之间的差距。在这方面，IJMHM将继续为材料科学家、工程师、设计师和制造商提供一个媒介。
