The phase/microstructure, mechanical properties and corrosion behavior of a series of binary Ti-Mn alloys with 5, 10, 15 and 20 wt% Mn were investigated in order to understand the effects of Mn content on mechanical properties, oxidation behavior, and electrochemical corrosion properties of Ti-Mn alloys. The phase/microstructure of Ti-xMn alloys was analyzed using X-ray diffractometry, scanning electron microscopy, and transmission electron microscopy. All examined properties of the Ti-Mn alloys were sensitive to the Mn content. The tested Ti-xMn alloys had alpha-Ti, beta-Ti, and alpha-TiMn phases. Ti-Mn alloy containing 5 wt% Mn composed of alpha-Ti, beta-Ti, alpha-TiMn, and isothermal omega phases. The proportion of alpha-Ti phase decreased and precipitation of beta-Ti phase increased with increasing wt% of Mn. Cast Ti-Mn exhibited higher hardness and better oxidation protection than commercially pure Ti (cp-Ti). The tested Ti-xMn alloys showed better corrosion resistance than the cp-Ti. Ti Mn alloy containing 5 wt% Mn had the highest hardness and lowest modulus, and is a good candidate for dental implant alloy. (C) 2016 Elsevier B.V. All rights reserved.
