MICROSTRUCTURAL EVOLUTION, MECHANICAL PROPERTIES AND CORROSION BEHAVIOUR OF LOW COST Ti-Fe-O-N (alpha-beta) ALLOYS 1. INTRODUCTION Titanium and its alloys are highly recognized materials employed for complex applications like aerospace, biomedical and chemical sectors ]. This is credited to the exceptional mechanical and physical properties exhibited by these metals. A few of these attributes include low density, certain strength, corrosion resistance, non porous and higher temperature resistance. The potentials these materials offer concerning biocompactibility, increased efficiency in fuel consumption, low thermal coefficient and environmental friendliness has brought it use to other general software like automobile, jewelry businesses, marine sectors merely to mention a few [1-2]. The most frequent type of ceramic alloy used in broad range of applications is called the вЂњtitanium function horse-Ti-6Al-4VвЂќ. The metals have great combination of mechanical properties because of the possibility of changing its complicated double phase (hcp О±+ bcc ОІ). microstructure through heat therapy . Other kinds of titanium alloys produced to meet specific requirements are the alpha alloys (commercially pure alloys), near alpha alloys and metastable beta metals [2-4]. All these alloys are considered as materials capable of replacing conventional industrial and structural materials like steel and cast iron. However, the production cost of these alloys was a restricting factor [5-8]. Consequently, attempts have been created by investigators to develop different ranges of low cost titanium alloys. Two significant approaches have been adopted to reduce the manufacturing cost of ceramic alloys . The very first approach involves replacing expensi...
