Microstructural Evolution, Mechanical Properties and Corrosion Behavior of Low Cost Ti-Fe-O-N Alloys

Development, mechanical properties, and corrosion behavior of microstructure of low cost Ti - Fe - ON (α - β) alloy Introduction Titanium and its alloys are widely recognized for advanced applications in aerospace, biomedical and chemical industries It is a material that is [1]. . This is due to the excellent physical and mechanical properties exhibited by these alloys. Some of these properties include low density, specific strength, corrosion resistance, nonmagnetic and high temperature resistance.

Copper and copper alloys are widely used in aqueous environments due to their nature in this environment, copper and copper alloys are antimicrobial and they also have strong mechanical and corrosion resistance in aqueous environments. Combining these characteristics makes it ideal for many aqueous applications such as condenser tubes, inlet screens, offshore structures, drinking water pipes and generator cooling systems.

In this study, corrosion and grinding behavior of three typical La - Mg - Ni alloys, La 2 MgNi 9, La 1.5 Mg 0.5 Ni 7 and La 4 MgNi 19 were systematically investigated. All alloys showed a multiphase microstructure with (La, Mg) Ni 3, (La, Mg) 2 Ni 7 and (La, Mg) 5 Ni 19 as the main phase. La 1.5 Mg 0.5 Ni 7 has better electrochemical performance in the three alloys. After the electrochemical cycle, the main product La (OH) 3 was found to be crushed and corroded by a combination of La 2 O 3, Mg (OH) 2 and MgO. The total corrosion degree of the electrochemical cycle alloy follows the order of La 2 MgNi 9, La 1.5 Mg 0.5 Ni 7> La 4 MgNi 19. It was found that mechanical properties are an important factor affecting the ability to resist chalking. As the stoichiometry of the B side of each phase increases, the Vickers hardness increases and is consistent with the powdering behavior of the alloy.

Bello KA et al. (2007) showed that tempering two-phase (ferritic and martensitic) steels have better quenched and tempered steel when studying the effect of tempering on the microstructure and mechanical properties of low carbon low alloy martensitic steels I found out. Higher strength, ductility and toughness. Sample 0.22% C microalloyed steel is austenitized and quenched to form lath martensite, then annealed in the critical region (Δε + Δε -) and then quenched to form a ferrite-martensitic microstructure . Phase

Magnesium alloy research has made major progress in the past 20 years and its remarkable improvement in collective performance shows this: strength, ductility, formability and even corrosion resistance. These improvements were achieved through the development of new alloys and new processing strategies. Alloy design strategies including precipitates of the second phase are broadly changing ultrafine precipitates ranging from two-phase microstructure including long period stacking ordered (LSPO) intermetallic compounds to super grain boundary having icosahedral quasicrystalline particles And a fine grain alloy up to the Guinier-Preston (GP) region of the micro alloying strategy aimed at increasing the number density. The effects of solid solution alloying of elements such as Y and Li continue to be of great interest to improve ductility and uniform corrosion resistance. Various experimental and simulation techniques and modeling have been applied to understand these phenomena.
