It is reported that researchers from the Technical University of Munich in Germany have reported a feasibility study on the composite manufacturing of EN AC-42000 alloy by combining laser powder bed melting and cold casting. The related research titled "Feasibility study on hybrid manufacturing combining laser based powder bed fusion and chill casting on the example of EN AC-42000 alloy" was publi...
Photoacoustic technology provides a non-invasive method for detecting biological tissues, but its clinical application is limited, partly due to the large volume and high cost of laser sources. A compact PA sensing instrument powered by laser diodes for biomedical tissue diagnosis can provide clinical doctors with a practical and effective tool for evaluating breast diseases.By providing a cost-ef...
Researchers from the Welding Research Institute of Aachen University of Technology in Germany reported on the development of a stable welding process for electron beam welding of thick plates used in the construction of offshore wind turbines. The relevant research results were published in Materials Science and Engineering Technology under the title "Development of a robust welding process for el...
