A novel composite porous coating approach for bioactive titanium‐based orthopedic implants
Publisher: Wiley
Date: 12-09-2012
DOI: 10.1002/JBM.A.34372
Abstract: Surface modification of titanium-based implants is considered a highly effective solution to enhance osseointegration. This study describes a novel Ti/hydroxyapatite (HA) composite porous coating produced using a cold spraying technique. Experimental results indicate desirable open-cell structure with 50-150 μm pore size and 60-65% macroporosity. In particular, the reinforced HA particles are exposed to the surface of the coating resulting in enhanced mineralization ability in simulated body fluid. None of the coatings displayed a cytotoxic response in SaOS-2 cells cultured in vitro for up to 48 h. The bond strength between the porous coating and the Ti substrate was found to be 20 MPa. These properties are comparative to or better than products currently on the market and thus this novel coating has potential use in orthopedics.

(Al,Mg)3La: a new phase in the Mg–Al–La system
Publisher: International Union of Crystallography (IUCr)
Date: 10-07-2018
DOI: 10.1107/S205252061800834X
Abstract: During an investigation of the Mg-rich end of the Mg–Al–La system, a new ternary phase with the composition of (Al,Mg) 3 La was identified. The crystal structure of this phase was determined by conventional X-ray powder diffraction and transmission electron microscopy analysis and refined using high-resolution X-ray powder diffraction. The (Al,Mg) 3 La phase is found to have an orthorhombic structure with a space group of C 222 1 and lattice parameters of a = 4.3365 (1) Å, b = 18.8674 (4) Å and c = 4.4242 (1) Å, which is distinctly different from the binary Al 3 La phase ( P 6 3 / mmc ). The resolved structure of the (Al,Mg) 3 La phase is further verified by high-angle annular dark-field scanning transmission electron microscopy.

Heteroepitaxy Crystallography in Low Dimensional Nanostructures
Publisher: Trans Tech Publications, Ltd.
Date: 06-2011
DOI: 10.4028/WWW.SCIENTIFIC.NET/SSP.172-174.1307
Abstract: Low dimensional nanostructures, e.g. nanowires, self-assembled through heteroepitaxy, present a variety of crystallographic features that do not always follow conventional V-W or S-K growth mode. Applying Δg parallelism rules and edge-to-edge matching (E2EM) model in β-DySi 2 /Si and CoSi 2 /Si systems provides a better understanding of the natural preference of the interface orientation and the orientation relationship (OR) during heteroepitaxial growth. This may help improving the quality of nanowires through optimizing the substrate orientation.
Grain structure control during metal 3D printing by high-intensity ultrasound
Publisher: Springer Science and Business Media LLC
Date: 09-01-2020
DOI: 10.1038/S41467-019-13874-Z
Abstract: Additive manufacturing (AM) of metals, also known as metal 3D printing, typically leads to the formation of columnar grain structures along the build direction in most as-built metals and alloys. These long columnar grains can cause property anisotropy, which is usually detrimental to component qualification or targeted applications. Here, without changing alloy chemistry, we demonstrate an AM solidification-control solution to printing metallic alloys with an equiaxed grain structure and improved mechanical properties. Using the titanium alloy Ti-6Al-4V as a model alloy, we employ high-intensity ultrasound to achieve full transition from columnar grains to fine (~100 µm) equiaxed grains in AM Ti-6Al-4V s les by laser powder deposition. This results in a 12% improvement in both the yield stress and tensile strength compared with the conventional AM columnar Ti-6Al-4V. We further demonstrate the generality of our technique by achieving similar grain structure control results in the nickel-based superalloy Inconel 625, and expect that this method may be applicable to other metallic materials that exhibit columnar grain structures during AM.

Abstract: Adding the peritectic forming element Cu effectively reduced the average grain size of cast Zn by over 85%. At a specified cast condition, the smallest grain size was obtained at 2 wt% Cu addition. A further increase in Cu content led to grain coarsening in the cast Zn–Cu alloys. Although the solute effect of Cu was predominately responsible for the grain refinement through restriction of the grain growth, it was found that the variation of grain size is also closely related to the formation of the pro-peritectic phase, ɛ-CuZn 4 . Crystallographic calculations using the edge-to-edge matching model showed low interatomic misfit and interplanar mismatch between Zn and the ɛ-CuZn 4 phase. In addition, a reproducible h.c.p.–h.c.p. (h.c.p. denotes hexagonal close-packed) orientation relationship between Zn and the ɛ-CuZn 4 particles (located within the Zn grain centres) was also experimentally determined using the electron backscattered diffraction method. This indicated the high potency of the pro-peritectic ɛ-CuZn 4 particles as effective heterogeneous nucleation sites for η-Zn, which further refined the Zn grains. However, when the Cu content was over 2.0 wt%, formation of large ɛ-CuZn 4 particles resulted in grain coarsening of the cast alloys.

Crystallographic study of grain refinement of Al by Nb addition

DOI: 10.1107/S1600576714004476
Abstract: The grain refinement of Al by the addition of a small amount of peritectic-forming solute, Nb, has been studied from the crystallographic point of view. Combining the observations of optical microscopy and scanning electron microscopy with the results of energy-dispersive X-ray spectroscopy and X-ray diffraction, it is confirmed that the particles observed at or near the grain centres of refined Al alloys are pro-peritectic Al 3 Nb particles. The crystallographic matching between the Al 3 Nb particles and Al grains has also been evaluated using an edge-to-edge matching model and further verified using electron backscatter diffraction and transmission electron microscopy. It is found that there are reproducible crystallographic orientation relationships between the Al 3 Nb particles and Al grains, and the experimental results are consistent with the predictions of the edge-to-edge matching model. This implies that the pro-peritectic Al 3 Nb particles are favourable nucleation sites for Al grains from the crystallographic point of view. Furthermore, the analysis of the size distribution of Al 3 Nb particles reveals that the Al 3 Nb particles at the grain centres have relatively large particle size, which also corroborates the high potency of Al 3 Nb according to the free growth model. It is therefore concluded that the significant grain refinement resulting from the addition of Nb is predominantly attributed to the in situ formed Al 3 Nb particles which promote grain refinement via enhanced heterogeneous nucleation.

Inoculation during Metal Castings: Beyond Grain Refining
Publisher: Trans Tech Publications, Ltd.
Date: 06-2010
DOI: 10.4028/WWW.SCIENTIFIC.NET/MSF.654-656.671
Abstract: Inoculation is the most common grain refining technique during metal/alloy castings. However, only a small fraction, typically 1~2%, of inoculants serve as nucleation sites while most of them do not participate in the nucleation event and hence they are usually termed ‘inactive’ inoculants. But ‘inactive’ does not mean ‘useless’. Our recent studies revealed some extra merits of these ‘inactive’ particles in Mg-Al-Y cast alloys. The current results represent a new approach to microstructure design through manipulation of inoculated particles during castings.

Abstract: Additive manufacturing, often known as three-dimensional (3D) printing, is a process in which a part is built layer-by-layer and is a promising approach for creating components close to their final (net) shape. This process is challenging the dominance of conventional manufacturing processes for products with high complexity and low material waste

Crystallography of self-assembled DySi2 nanowires on a Si substrate
Publisher: AIP Publishing
Date: 23-02-2009
DOI: 10.1063/1.3085772
Abstract: A recently developed crystallographic model, edge-to-edge matching, has been used to interpret the crystallographic features of self-assembled DySi2 nanowires on Si substrates. All of the observed orientation relationships (ORs) and interface orientations of the DySi2 on Si(111), (001), and (110) were predicted by one criterion. The calculated results are fully consistent with the previous high-resolution transmission electron microscopy observations. The preference for each OR and interface was discussed in terms of the competition between thermodynamics and kinetic factors. This model can also be used in other epitaxy systems and has strong potential for future nanostructure design.
