“…Various materials are being explored as candidates for such applications with an aim to improve their properties by SPD processing. [155] The archetypal alloy systems that offer the best performance for these two kinds of applications are arguably those based on titanium and magnesium. Indeed, Ti forms a protective surface layer of titania and is considered to be bio-inert (thus being suitable for permanent implants) whilst Mg is very reactive and biodegradable.…”

Bulk nanoSPD materials are materials with nanostructural features, such as nanograins, nanoclusters, or nanotwins, produced by severe plastic deformation (SPD) techniques. Such nanostructured materials are fully dense and contamination free and in many cases they have superior mechanical and functional properties. Here, we provide a critical overview of such materials, with a focus on the fundamentals for the observed extraordinary properties. We discuss the unique nanostructures that lead to the superior properties, the underlying deformation mechanisms, the critical issues that remain to be investigated, future research directions, and the application potential of such materials.

“…[56][57][58][59][60] Not surprisingly, the mechanical performance of CP Ti of biomedical grades was improved significantly upon processing by ECAP. A recent study of the properties of Ti processed by a combination of ECAP-Conform and drawing 61 returned record values of the ultimate tensile strength (1330 MPa) and fatigue strength (620 MPa).…”

It is now well established that the processing of bulk solids through the application of severe plastic deformation (SPD) leads to exceptional grain refinement to the submicrometer or nanometer level. Extensive research over the last decade has demonstrated that SPD processing also produces unusual phase transformations and leads to the introduction of a range of nanostructural features, including nonequilibrium grain boundaries, deformation twins, dislocation substructures, vacancy agglomerates, and solute segregation and clustering. These many structural changes provide new opportunities for fine tuning the characteristics of SPD metals to attain major improvements in their physical, mechanical, chemical, and functional properties. This review provides a summary of some of these recent developments. Special emphasis is placed on the use of SPD processing in achieving increased electrical conductivity, superconductivity, and thermoelectricity, an improved hydrogen storage capability, materials for use in biomedical applications, and the fabrication of high-strength metal-matrix nanocomposites.

“…Nanostructured RE 2 Fe 14 B (RE = Nd, Pr)-based alloys with high coercivity H C up to 2240 kA/m were produced via HPT followed by annealing at 600°C [32]. Similar results were reported for melt-spun Nd 9 Fe 85 B 6 alloy [33]. Metal-ceramic powder mixtures consisting of Co (ferromagnetic) and NiO (antiferromagnetic) phases were compacted by HPT both with and without a prior BM [34].…”

Bulk Nanostructured Materials With Multifunctional Properties

As seen from Chap. 3 of this book, nanostructuring of various metallic materials is a key for obtaining extraordinary multifunctional properties that are very attractive for different structural and functional applications. Materials experts have asserted that materials breakthroughs in the twentieth century required about 20 years from the time of invention to gain widespread market acceptance [1].1 Bulk nanostructured metallic materials also have been following this track. Despite a wide research started at the beginning of 1990, very significant progress in their commercialization has been made just in recent years, which is evident by the first production of advanced pilot articles from nanostructured metals and alloys with new functionality. These aspects of innovations of bulk nanostructured metallic materials processed by SPD are discussed in this chapter.Application and commercialization of bulk nanostructured metallic materials are associated with three primary points: their superior properties, their efficient fabrication, and the possibility to produce cutting-edge products from these materials. Analytical reports documented more than 100 specific market areas for nanostructured metals [2,3], and it is evident that many of these new structural and functional applications involve extreme environments where exceptional strength and improved functional properties are needed. Below are the examples of nanomaterials developments for their innovation applications in engineering and medicine. Nanostructured Ti and Ti Alloys for Biomedical EngineeringPure Ti possesses the highest biocompatibility with living organisms, but it has limited use in medicine due to its low strength.
