Abstract: The use of lightweight structural elements across various industries has seen significant progress due to the adoption of carbon fiber-reinforced polymers (CFRPs). Among these, polyamide 6 (PA6) stands out as a prevalent thermoplastic polymer, renowned for its exceptional processability, favorable mechanical attributes, and cost-effectiveness. These qualities position it as Leia mais…

Abstract: The quantification of rare earth elements in (Nd-Pr)-FeB alloys used in the production of super magnets is required to ensure the quality of the raw material and a final product with suitable properties. Laser-induced breakdown spectroscopy is attractive to this aim by avoiding the need for decomposition of the Leia mais…

Abstract: This study delves into the formulation of an advancedmicrostructure in medium-carbon high silicon spring steel through a series of engineered heat treatments. The microstructure, composed of lower bainite, proeutectoid ferrite, and pearlite, exhibits superior mechanical properties compared to traditional pearlitic steel. Specifically, the novelmicrostructure yields a strength of 870 Leia mais…
