1 Introduction Tungsten is considered one of the candidate materials for high-temperature plasma environments in nuclear fusion reactors due to its advantages of high density, high melting point, high strength, high hardness, high thermal conductivity, low physical sputtering rate, and low hydrogen...

  As one of the typical representatives of high-density tungsten-based alloys, tungsten-nickel-iron (W-Ni-Fe) alloy has a wide range of applications in modern science and defense and civilian industries, such as radiation protection and guidance, industrial counterweights, nuclear energy and en...

The aging population has led to a year-on-year increase in the prevalence of musculoskeletal diseases. Among these, bone defects represent the most common orthopedic condition, characterized by partial skeletal loss caused by severe limb trauma, bone infections, tumors, and osteomyelitis. Globally,...

Molybdenum metal is an indispensable material in many industries due to its strength at high temperatures. Some applications require complex shapes that are difficult to machine, making 3D printing a viable solution for producing intricate components. However, defects often arise when manufacturing...

  In today's medical context, the treatment of bone defects remains an important clinical problem [1]. Large bone defects are usually unable to be repaired by the body's own self-repair ability [2]. Therefore, the key problem in the treatment of bone defects is the lack of fusion between the gr...

CoCrNi MEAs exhibit excellent mechanical properties, particularly at low temperatures [1–3], and hold promise as a replacement for stainless steel materials in structural components for marine environments [4–5]. However, in marine service environments, high Cl– content can easily...

1. Introduction   Since molybdenum is one of the high melting temperature materials and has superior ductility and toughness compared to tungsten, it is often used for ultra-high temperature components, such as rotating anodes of X-ray tube, electrodes for melting glass and hot metal forming di...

0 Introduction With the rapid development of the manufacturing industry, product structures have become increasingly complex, and the structural complexity of mechanical components and the requirements for their processing precision have continued to rise [1]. Traditional mechanical processing metho...

1. Introduction   Selective laser melting (SLM) is a laser based rapid manufacturing technology that builds metal parts layerby-layer using metal powders and a computer controlled laser (Ref 1, 2). A components computer aided design (CAD) model is sliced into thin layers mathematically. After c...

0 Introduction In 2016, alkali leaching residue (tungsten slag) produced by the alkali decomposition method was officially included in the National List of Hazardous Wastes [1]. Over the past few decades, China has accumulated millions of tons of tungsten slag, with an annual increase of nearly 80,0...

  With the development of aerospace technology, the nozzle inlet temperature requirements for advanced aircraft engines are constantly increasing, while the weight is also being reduced. Niobium alloys have high operating temperatures, but high density and high price; titanium alloys have low d...

0 Introduction Surface ships are susceptible to damage from explosive shock wave loads [1-3]. With the continuous development of industrial technology, the demand for lightweight ship protection structures has become increasingly urgent. There are two common methods for achieving structural lightwei...
