The melting process during laser powder bed fusion (LPBF) is accompanied by complex physical phenomena, which can be rarely scaled with acceptable effort to utilize the in component design obtain tailored mechanical properties adequate machine productivity. A constitutive law relating melt pool geometry parameters thereby plays an essential role practically fostering productivity and quality LP...

In electrical discharge machining (EDM), gap control is the key to stable processing; plays a significant role in EDM. To determine influence of on material removal and melt pool movement, which are two fundamental issues EDM, high-speed photography molecular dynamics (MD) simulations were used study process. Research results demonstrate that has during A smaller width produces more larger remo...

Glass is a critical material for many scientific and engineering applications including optics, communications, electronics, and hermetic seals. Despite this technological relevance, there has been minimal research toward Additive Manufacturing (AM) of glass, particularly optically transparent glass. Additive Manufacturing of transparent glass offers potential advantages for lower processing co...

Fused silica glass is a commonly used high-performance material. However, due to the high temperature necessary for its production, manufacturing can also be challenging and costly. An attractive approach additive through laser cladding. Laser cladding of transparent fused was achieved using CO 2 -laser locally melt substrate while injecting stream fumed powder into melt-pool. By described tech...

Growing protoplanets experience a number of impacts during the accretion stage. A large impactor hits surface protoplanet and produces impact-induced melt, where impactor's iron emulsifies experiences metal-silicate equilibration with mantle while it descends towards base melt. This process repeatedly occurs determines chemical compositions both core. The partitioning is controlled by parameter...

Laser powder bed fusion (LPBF) has made significant progress in producing solid and porous metal parts with complex shapes geometries. However, LPBF produced often have defects (e.g., porosity, residual stress, incomplete melting) that hinder its large-scale industrial commercialization. The process involves heat transfer fluid flow, the melt pool is a critical component of process. stability f...

Laser direct energy deposition (L-DED) can improve the forming efficiency of parts by controlling laser power, scanning speed, powder flow rate, and spot size. It is a good way to complete processing repair complex parts. In this paper, three-dimensional numerical model established study dynamic cladding process (pool geometry, transfer, solidification) Inconel718 alloy during deposition. The f...
