Niobium-tungsten alloy Nb521 (Nb-5W-2Mo-1Zr) is a kind of high-temperature alloy independently developed by China, which has a high melting point, good high-temperature (1650°C) strength, and compared with refractory metals, such as tungsten, molybdenum and tantalum alloys, it has the advantages...

1 Performance of High-density Tungsten Alloy Tungsten has many excellent properties such as high melting point and high density, but its application is often limited by its brittleness. In order to change the brittleness of tungsten, a new tungsten alloy was successfully developed in 1938 internatio...

1 Introduction Accompanied by the development of aerospace technology, the quality and performance requirements for parts are also increasing. Vehicle parts often work in the high temperature and high speed airflow strong erosion of the environment, bear a very serious aerodynamic heating [1], which...

High specific gravity tungsten alloy is a kind of tungsten as the main body, adding a small amount of Ni, Fe, Cu, Co, Mn and other elements composed of alloy, its tungsten mass fraction is generally 85% ~ 98%, the density of up to 16.5 ~ 19.0g/cm3, and therefore is often referred to as a high specif...

0 Introduction With the continuous development of global nuclear energy technology, nuclear-powered ships, as an important part of future marine strategic forces, have become particularly important in terms of technological development. However, the development of domestic nuclear-powered ship techn...

1 Preface Selected zone laser melting (SLM) is a new rapid prototyping (RP) technology that has emerged in recent years. This technology is an additive manufacturing process that produces parts by melting a powder bed layer by layer using a laser beam as the energy source and pre-established CAD dat...

Introduction As a new product manufacturing technology, additive manufacturing has received widespread attention in recent years. Since its emergence in the late 1980s, after more than 20 years of development, the potential of additive manufacturing technology has been continuously explored, and its...

As a refractory metallic material with a body-centered cubic structure, tantalum is used in a large number of applications in the electrical and electronics industry, especially as a capacitor that needs to store a large amount of potential energy, due to the high reactivity of tantalum with oxygen...

Molybdenum and molybdenum alloys have become important materials for electronic and power equipment manufacturing, metal material processing, glass manufacturing, high-temperature furnace structural component manufacturing, aerospace and defense industry applications due to their good thermal conduc...
