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...

  Tantalum is a kind of refractory metal with high melting point and high boiling point. It has excellent processing performance and corrosion resistance [1] and is mainly used as capacitors, rare earth smelting and corrosion-resistant containers for chemical industry [2-3]. Compared with pure...

  With the development of my country's aerospace technology, the requirements for parts quality and performance are also increasing. Some aerospace parts often serve in an environment with strong erosion caused by high-temperature and high-speed airflow, and are subjected to very severe aerodyn...

Molybdenum and molybdenum alloys possess advantages such as high melting point, excellent electrical and thermal conductivity, corrosion resistance, low thermal expansion coefficient, and good thermal shock resistance, making them widely used in fields such as electronics, machinery, metallurgy, nuc...

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...
