Microstructural Features and Mechanical Behavior of Laser Welded Magnesium Alloy Sheet

Magnesium Alloy is gaining momentum now a days as it is light in weight and possess moderate strength. Automotive and aerospace industries and electronics companies looking for light and strong and smart materials to save fuel and emission free environments, which magnesium alloy can meet. As Tailor welded magnesium alloy sheets are in demand, AZ31B -H24 magnesium alloy sheet with 2 mm thickness is selected in this research work. Laser welding is used to join magnesium alloy sheets in butt configuration. The samples are analyzed, and observations and challenges are addressed with help of micrographs for further scope of work. Effect of laser welding on grain or microstructure changes are also outlined. Thorough micro structural analysis is carried out with an objective to capture grain structure near parent metal, left and right-hand sides of heat affected zone and weld line. Impact and hardness tests are conducted to assess the mechanical behavior of laser welded samples

A Review on Metal Binder Jetting 3D Printing

Binder jetting (BJ) is one of the major metal additive manufacturing (AM) technology used for the production of intricate metal components using a layer-by-layer approach. It belongs to the more general family of processes known as powder bed fusion procedures, in which a bed of metal powder is first selectively fused together with the help of a binder and then sintered in order to produce the final metal component. Binder Jetting is the sole non-fusion-based powder bed additive manufacturing technology; this means that, unlike laser-based AM procedures, the resulting parts are completely free of residual stresses. Small to medium batch production can be cost-effective due to lower tooling and setup expenses. This analysis focuses on the capacity of some of the most important engineering materials, including titanium, Inconel and stainless steel, to produce intricate geometries with a high degree of precision and accuracy. These materials find extensive use across many applications, including defence, industry, biomedical, aerospace, and other fields
