TL;DR: In this paper, the authors investigated the kinetics of localized corrosion of 5083 aluminium alloy and showed that the importance of iron-rich and Mg2Si intermetallics phases in the initiation of corrosion processes is demonstrated.

TL;DR: In this paper, a single phase multi-component alloys up-to-date with promising mechanical properties at cryogenic temperatures, including corrosion resistance, is studied. But, the study on the corrosion behavior of CrMnFeCoNi HEA coating has still been lacking.

TL;DR: In this article, the effects of selective laser melting (SLM) on the microstructure and mechanical properties of A357 aluminium alloys were investigated, where the SLM processing parameters were optimised to achieve maximum density, corresponding to an extremely fine micro structure with very few pores, which translates to differences in mechanical properties compared to conventional cast alloy.

TL;DR: In this article, the authors presented data on new wrought weldable alloys based on the Al-Mg-Sc system, namely, 01515, 01523, 01535, 01545, 01570 and 01571, which differ from each other mainly by magnesium content and belong to the family of non-heat-treatable Alloy alloys.
Abstract: Data on new 01515, 01523, 01535, 01545, 01570 and 01571 wrought weldable alloys based on the Al–Mg–Sc system are presented. These alloys differ from each other, mainly, by magnesium content and belong to the family of non-heat-treatable alloys. Wrought Al–Mg–Sc alloy semiproducts as-hot worked or as-annealed show much higher properties (especially yield strength) than those made from conventional Al–Mg alloys with the same magnesium content. Strengthening relates to both direct strengthening effect of the secondary Al3Sc particles and development of a stable nonrecrystallized structure. Of Al–Mg–Sc alloys, 01570 alloy containing about 6% Mg has found the widest application. Yield strength of hot worked or annealed 01570 alloy semiproducts is at a level of 300 MPa, while yield strength of semiproducts made from a similar scandium-free alloy is about 180 MPa. Prospects of the usage of the new alloys for production of various structures are discussed.

TL;DR: In this article, the microstructure and mechanical properties of H13 alloy are described using the direct metal deposition (DMD) technique, which is the state-of-the-art for die and tool manufacturing.
Abstract: The rapid prototyping process has reached the stage of rapid manufacturing via the direct metal deposition (DMD) technique. The DMD process is capable of producing three-dimensional components from many of the commercial alloys of choice. H13 tool steel is a difficult alloy for deposition due to residual stress accumulation from martensitic transformation; however, it is the material of choice for the die and tool industry. This article reviews the state of the art of DMD and describes the microstructure and mechanical properties of H13 alloy deposited by DMD.
