Microstructural Effect of Iron In Titanium Zirconium Alloys

Abstract

ABSTRACT The report starts with an introduction of basic concepts of some metals are titanium, zirconium, iron, molybdenum etc, which exhibit excellent physical, chemical and mechanical properties after alloying. Design and implementation of these kind of alloys possible by metallurgical development for different compositions required. Many reactive metals are difficult to prepare in pure form without complex procedures. Alloy development is the key factor for development of better materials for engineering applications. To maintain the superior biocompatibility, corrosion resistance etc of some alloy elements especially in biomedical implants and consumer applications like eye glasses, wrist watches are becoming major attaraction for human kind in the present days due to excess skin allergies caused by metal ions reactions of biomedical implants Further, the most important characteristic property before alloying has to be considered is corrosion resistance. As no metal, or alloy, is entirely inert to corrosion, it is important to understand the characteristics before using it in any applications. The result indicates that addition of iron in Zirconium improves the effect of β-phase stability and improves the properties of titanium zirconium alloys for many applications. Hence we proposed to study the phase behaviour of the Zr-Ti-Fe alloy along with characterization of the alloys. Hence in this MTech thesis we focus on the effect of iron on (Zr-Ti) alloy and microstructural and mechanical properties. In this study, alloys are to be fabricated by arc melting followed by polishing and etching treatments to achieve observe optical microstructural effect of the alloys. Further alloys will be characterised by X-ray
