Influence of Defects on the Structural-phase State of Welded Joints and Parameters of Acous
Summary
This technical paper examines how iron impurities in aluminum affect the microstructure and ultrasonic properties of aluminum alloy welds. This is a metallurgy and welding engineering paper with no connection to microplastics or environmental health.
Iron is always present in aluminum, as it is the predominant impurity of technical aluminum and the main impurity of pure aluminum. It gets into aluminum when using steel equipment during melting and casting, a significant part - from the raw material for the production of aluminum - alumina.
