TL;DR: In this article, a detailed analysis of the electrochemical impedance spectra obtained for the Mg electrode during immersion in a sodium sulfate solution is presented, where various parameters are extracted such as the thin oxide film thickness, the resistivity at the metal/oxide film interface and at the oxide film/electrolyte interface, the active surface area as a function of the exposure time to the electrolyte, the thickness of the thick Mg(OH)2 layer and the kinetic constants of electrochemical reaction.

TL;DR: In this article, a face centered cubic carbide with lattice parameter a = 0.417028(4)nm was observed in spray formed AISI M2 high-speed steel.

TL;DR: In this article, an overview about the microstructures present in high-speed steel, focused on the crystallography of the carbides, is presented, in which the validation of this identification when it is considered that other atoms in the structure are substitutional is discussed.

TL;DR: In this paper, the Ca2Mn1Re1O6 double perovskite has been prepared in polycrystalline form by using the encapsulated quartz tube method using the partial oxygen pressure inside the quartz tube revealed this to be a crucial synthesis parameter for the production of a single structural phase sample.

TL;DR: In this paper, the corrosion resistance of 17-4PH powder injection-molded (PIM) martensitic stainless steel (SS) was evaluated in naturally aerated sodium chloride (NaCl) solution (3 wt%) at 25°C.
