タングステンカーバイド産業における多孔性：概要説明

Introduction Porosity is a critical concept in materials science, especially when it comes to high-performance materials like tungsten carbide (WC) used in industrial tools. Though often overlooked, porosity plays a significant role in determining the mechanical strength, wear resistance, and overall reliability of carbide tools. This article breaks down what porosity is, how it forms, why it matters, and how manufacturers manage it. What Is Porosity? Porosity refers to the presence of tiny voids or pores within a material. These voids may be microscopic or visible to the naked eye, and they result from incomplete densification during the manufacturing process. In cemented carbides, porosity is the space that remains unfilled […]

炭化タングステン工具の粒度について

In the world of advanced materials and tooling, one term that frequently arises is “grain size.” While it might sound like a detail only metallurgists care about, grain size plays a critical role in the performance, strength, and durability of tungsten carbide tools used across mining, machining, oil & gas, and precision manufacturing industries. So—what is grain size, and why should you care? What Is Grain Size? Grain size refers to the average size of the individual tungsten carbide (WC) particles in a cemented carbide material. These particles are tightly bonded together by a metallic binder (usually cobalt or nickel), forming a composite material with exceptional hardness and strength. Grain […]

炭化タングステン工具の合金元素について

Tungsten carbide tools are renowned for their exceptional hardness, wear resistance, and ability to withstand extreme working conditions. But behind this impressive performance lies more than just WC and cobalt—it’s also the result of carefully selected alloying elements. These trace additions may be small in quantity, but they have a big impact on tool behavior, durability, and microstructure control. This article explores what alloying elements are, why they are added, and how they affect the performance of cemented carbide tools. What Are Alloying Elements? In materials science, alloying elements are elements that are intentionally added in small quantities to a base metal or composite to modify its properties. In the […]
