For a variety of examples, including Ti-6Al-4V, Co-Cr-Mo superalloy, Ni-base superalloy systems , Nb, and Fe, the metallurgy of selected metal and alloy components fabricated by additive metallurgy using electron beam melting (EBM) is presented.
A variety of EBM process parameters, including beam scan strategies, beam current variations, and cooling rate features, are used to preheat and selectively melt powders that have been alloyed and prepared.
In contrast to more typical wrought and cast products, selected systems’ microstructures and residual mechanical properties are discussed. Columnar microstructural architectures, the result of melt-solidification phenomena occurring layer by layer, are one of the novel characteristics of EBM fabrication.
The incremental layer-by-layer melt and solidification phenomena associated with the laser and electron beam AM of metal or alloy powders differs fundamentally from more conventional metallurgical processing, including directional solidification involving a continuously moving melt/solidification front .
In addition, traditional metallurgical processing of bulk melt/solidification products involving thermo-mechanical treatment regimens can be facilitated to some extent in the AM of the same products by adjusting and optimizing beam scan parameters and scan sequencing strategies to achieve desired microstructural features incrementally rather than by bulk cast or wrought product post treatment.
The Global Metallurgical Additives market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Xilong Brand Food Additives Use in Metallurgical CAS11138-66-2food Additives Xanthan Gum – Xanthan Gum is the most superior metallurgical additive in the worldwide with the performance of thickening, suspending, emulsifying, and stabilizing.
Xanthan gum can be quickly dissolved in water and have a good effect on the insoluble solids and oil droplets’ suspending. Xanthan gum has the characteristics of low concentration but high viscosity (1% aqueous solution viscosity of 100 times gelatin), is a highly efficient thickener.
Widely used as salt/acid resistant thickener, high efficient suspension agent and emulsifier, high viscosity filling agent in various food and beverage. It can not only enhance the performance of water-keeping and shape-keeping, but also improve the freeze/thaw stability and taste of food and beverage products.
