Micro-hardness and Young's modulus of a thermo-mechanically processed biomedical titanium alloy

Abstract

This paper presents a study on the influence of different thermo-mechanical processing (TMP) parameters on some required properties such as micro-hardness and Young's modulus of a novel near β alloy Ti-20.6Nb-13.6Zr-0.5V (TNZV). The TMP scheme comprises of hot working above and below β phase, solutionizing treatment above and below β phase coupled with different cooling rates. Factorial design of experiment is used to systematically collect data for micro-hardness and Young's modulus. Validity of assumptions related to the collected data is checked through several diagnostic tests. The analysis of variance (ANOVA) is used to determine the significance of the main and interaction effects. Finally, optimization of the TMP process parameters is also done to achieve optimum values of the micro-hardness and Young's modulus.

Effect of Al2O3–Ti composite coating on corrosion behavior of TiAl6V4 alloy

“…The present paper deals with the production of high surface quality biofilms using EPD without structure, which contains microcracks and voids as prominent characteristics of microstructures of plasma sprayed films . The microstructure of the coating affects the other film characteristics like electrochemical and mechanical behaviors . Figure shows SEM surface morphology of coated TiAl 6 V 4 samples with Al 2 O 3 –Ti at three compositions 30, 50, and 70 wt% Ti.…”

A general model for the crystal structure of orthorhombic martensite in Ti alloys

“…This search has led to the development of a wide array of novel Ti alloy formulations exhibiting SME or superelasticity (SE). Notably, the mechanical instability of austenite in high-alloy formulations may not only trigger SE but may also give rise to very low elastic moduli (approaching that of human bone, Young's modulus < 30 GPa), making such alloys preferred for load-bearing biomedical applications (Li et al, 2014;Laheurte et al, 2010;Mohammed et al, 2014;Lee et al, 2012).…”

Estudio de perfiles de difracción de rayos X de una aleación Ti-13Ta-3Sn obtenida por aleado mecánico

“…Considerando la clasificación anterior, es posible seleccionar los elementos estabilizadores y neutros, que cumplan con características de biocompatibilidad, de acuerdo con los trabajos realizados por Steimemann y Kawahara [3,17] (Figura 1). Así, los candidatos pueden incluir el Nb, Zr, Mo, Ta y Sn, siendo los últimos dos, los mejores en biocompatibilidad [18][19][20].…”
