1. Introduction   Tungsten has a high energy threshold for physical sputtering (Eth~200 eV for D) and does not form hydrides or co-deposits with tritium. In addition, it has the highest melting point of all metals, the lowest vapor pressure, good thermal conductivity, and high temperature stren...

In traditional manufacturing, for complex structures, casting and forging processes are usually costly and inefficient [1-4]. Additive manufacturing technology based on CAD/CAM design, through the discrete stacking principle of layer-by-layer manufacturing entity, can break through the bottleneck of...

Nickel-based high-temperature alloys are widely used in aerospace engine turbine discs and turbine blade materials for their high strength and good creep resistance, etc., and their excellent mechanical properties are mainly attributed to the precipitation reinforcement of γ'-Ni3Al (L12 ordere...

  Ta-10W alloy has the characteristics of high melting point, high high temperature strength and excellent corrosion resistance, and is suitable for high temperature, high pressure, corrosion resistance and ablation resistance working environment. The explosive composite technology is used to m...

Aero-engines are developing in the direction of high power and high thrust, and the increase in inlet temperature of turbine engines leads to the difficulty of existing high temperature alloys to meet the requirements, and the application of thermal barrier coatings (TBCs) is the most effective way...

1. Introduction   Niobium has attracted a considerable interest for many applications such as steel production, superalloy production(as alloy additions), and transport industry (aircraft turbine engines, magnetically levitated trains, and automobiles) owing to its high melting point (2741 K),...

Bone defects caused by congenital bone disease, trauma, and infections are common clinical conditions, which usually require the implantation of bone restorative materials for treatment[1] . Depending on the material, bone repair implant materials can be categorized into three types: metal, polymer...

  With the rapid development of industry and the great improvement of people's living standards, the amount of civil and commercial electricity consumption has grown from kilowatts to megawatts. The traditional power generation model is not only difficult to meet the growing electricity consump...

The enhancement of the charging and discharging performance of tantalum capacitors and the preparation of highly reliable tantalum electrolytic capacitors are the main areas of development and competition in the current industry, and tantalum powder, as a raw material for the production of capacitor...

1.Introduction   Because of its high melting point, low thermal expansion, high thermal conductivity, low neutron yieldunder energetic particle irradiation, low sensitivity to hydrogen, and other favorable properties,tungsten (W) is currently considered a top candidate as a plasma facing materi...

0 Introduction  Since the discovery of the polyenergy effect by Munroe [1] in 1888, polyenergy charges have been widely used in the combat sections of munitions and engineering fields. After several centuries of development, the application of poly energy charge in the combat part is now mainly...

0 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 ex...
