“…The O&P Young's modulus very nicely agree with the reference value of 72 GPa. The O&P hardness is in better agreement than the C&C hardness with other published results [10][11][12], even without a reference value to be compared to.…”

The microstructure, mechanical behaviour, and biocompatibility (cell culture, morphology, and cell adhesion) of nanostructured Ti45Zr15Pd35‐xSi5Nbx with x = 0, 5 (at. %) alloys, synthesized by arc melting and subsequent Cu mould suction casting, in the form of rods with 3 mm in diameter, are investigated. Both Ti‐Zr‐Pd‐Si‐(Nb) materials show a multi‐phase (composite‐like) microstructure. The main phase is cubic β‐Ti phase (Im3m) but hexagonal α‐Ti (P63/mmc), cubic TiPd (Pm3m), cubic PdZr (Fm3m), and hexagonal (Ti, Zr)5Si3 (P63/mmc) phases are also present. Nanoindentation experiments show that the Ti45Zr15Pd30Si5Nb5 sample exhibits lower Young's modulus than Ti45Zr15Pd35Si5. Conversely, Ti45Zr15Pd35Si5 is mechanically harder. Actually, both alloys exhibit larger values of hardness when compared with commercial Ti‐40Nb, (HTi‐Zr‐Pd‐Si ≈ 14 GPa, HTi‐Zr‐Pd‐Si‐Nb ≈ 10 GPa and HTi‐40Nb ≈ 2.7 GPa). Concerning the biological behaviour, preliminary results of cell viability performed on several Ti‐Zr‐Pd‐Si‐(Nb) discs indicate that the number of live cells is superior to 94% in both cases. The studied Ti‐Zr‐Pd‐Si‐(Nb) bulk metallic system is thus interesting for biomedical applications because of the outstanding mechanical properties (relatively low Young's modulus combined with large hardness), together with the excellent biocompatibility. © 2014 Wiley Periodicals, Inc.

“…Several authors have explored this relationship using indentation measurements finding that in many, but not all cases, E′ and H′ are positively correlated. 18,19 From the metals data shown in Fig. 2 one finds that the correlation coefficient between E and H ρ EH = 0.78.…”

It is often advantageous to display material properties relationships in the form of charts that highlight important correlations and thereby enhance our understanding of materials behavior and facilitate materials selection. Unfortunately, in many cases, these correlations are highly multidimensional in nature, and one typically employs low-dimensional cross-sections of the property space to convey some aspects of these relationships. To overcome some of these difficulties, in this work we employ methods of data analytics in conjunction with a visualization strategy, known as parallel coordinates, to represent better multidimensional materials data and to extract useful relationships among properties. We illustrate the utility of this approach by the construction and systematic analysis of multidimensional materials properties charts for metallic and ceramic systems. These charts simplify the description of high-dimensional geometry, enable dimensional reduction and the identification of significant property correlations and underline distinctions among different materials classes. INTRODUCTIONThe mapping of material properties, pioneered by Ashby and coworkers, leads to the creation of charts that condense a large quantity of information into a useful representation that has the virtue of revealing important property correlations and that facilitates materials selection and design.1,2 These (usually twodimensional) charts form the basis of an optimized, systematic methodology for materials selection based on materials informatics. In particular, this program involves the identification of technical design requirements and the associated materials indices used for materials selection to meet these requirements.
