摘要: This paper presents a study on microstructure, elasticity modulus and electrochemical behavior of Ti-26Nb, Ti-26Zr Ti-26Ta binary alloys obtained in an induction furnace equipped with water cooled copper crucible which can promote levitation the moltem alloys. The microstructures eletrochemical were investigated by means X-ray fluorescence spectroscopy, diffractometry, optical microscopy, microvickers hardness, open circuit poten- tial, corrosion potential polarization resistance. results revealed that difference nominal chemical composi- tion related to contamination was extremely low, indicates this melting technique is highly appropriate for ob- taining contaminant-free titanium alloy. addition niobium very favorable obtaining near-β alloy low modulus. Additionally, Ti-26Nb presented best resistance combined
