TL;DR: In this article, microscopic morphological features of the cubic chromium and nodular titanium powders prepared by electroreduction of the respective oxides in molten salts (the FFC Cambridge process) are compared with the preferential crystal growth mechanism.
Abstract: Microscopic morphological features of the cubic chromium and nodular titanium powders prepared by electroreduction of the respective oxides in molten salts (the FFC Cambridge process) are compared with the preferential crystal growth mechanism. The analysis leads to an understanding of determining forces for the formation of cubic particles in the chromium powders owing to preferential growth, but nodular particles in the titanium powder owing to interruption of the preferential growth by particularly oxygen atoms.

TL;DR: The objective of the present study was to investigate high velocity compaction of titanium powder and to prepare a dense composite biomaterial of titanium and hydroxyapatite with the purpose of forming dental components with improved early healing properties.
Abstract: The objective of the present study was to investigate high velocity compaction of titanium powder and to prepare a dense composite biomaterial of titanium and hydroxyapatite with the purpose of forming dental components with improved early healing properties. A high purity titanium powder was compacted using high velocity compaction to study the density distribution. Then, a titanium–hydroxyapatite composite was prepared by mixing titanium powders and hydroxyapatite grains. Dental implant components were formed from the high velocity compacted specimens, exposing the hydroxyapatite grains at the component surface. The green density reached more than 98·5% after more than one impact. The composite was heated to 500°C, enough to bind the titanium grains, but to avoid observable reactions. Compacted pure titanium could be sintered to full density. The heated composite material reached 99% density, no reaction was observed between titanium and hydroxyapatite, and the composite material could be formed...

TL;DR: In this article, a powder mixture of aluminum, 10-wt% titanium, and 1.5% of a wax acting as process control agent (PCA), has been attrition-milled for 2-20h.
Abstract: A powder mixture of aluminum, 10 wt% titanium, and 1.5 wt% of a wax acting as process control agent (PCA), has been attrition-milled for 2–20 h. Titanium powder had been previously ground to a lower particle size to make it similar to the as-received aluminum particle size. The overall aim of this work was to achieve a metastable titanium solution in the aluminum matrix. Changes with milling time of particle size and shape, microstructure, hardness and other powder characteristics have been studied. Given the used experimental-conditions, a process time of 10 h has been selected for the mechanical alloying (MA) of Al–10Ti powder, attaining a compromise between uniform microstructure development and a not so long processing time. At this milling time aluminum dissolves about 9 wt% Ti, increasing its Vickers microhardness (202 VH20) more than 10 times with reference to the starting Al powder (20 VH20). Milled particle size is smaller than the starting one (17 vs. 44 μm). Increasing milling for longer times, up to 20 h, does not produce important changes in powders structure.

TL;DR: In this paper, the effects of solvent and thermal debinding, and vacuum sintering, on binder removal efficiency, sintered microstructures, and mechanical properties of PIM HDH titanium compacts were investigated.
Abstract: The optimum solids loading for hydride-dehydride (HDH) titanium powder injection molding (PIM) feedstock was determined by torque rheometry, and homogeneous feedstock was prepared utilizing a twin-shaft, co-rotating mixer. The effects of solvent and thermal debinding, and vacuum sintering, on binder removal efficiency, sintered microstructures, and mechanical properties of PIM HDH titanium compacts were investigated. The optimum temperature for solvent debinding was in the range of50°C-60°C at which >97 w/o of the soluble binder was extracted after a 4.0 h solvent immersion. For subsequent thermal vacuum debinding, a slow heating rate (1 °C/min) between 200°C and 450°C was beneficial in removing the remaining polymeric binders. After sintering in vacuum at 1,250°C, the relative density reached 98% of the pore-free level, but a hard surface layer consisting of α-titanium, TiC, and trace TiO 2 was readily formed. The tensile strength and elongation of the sintered titanium were 349 MPa and 6.4%, respectively. Prolonged sintering degraded the tensile properties.

TL;DR: In this paper, the sintering kinetics and mechanisms of micron-size and nanocrystalline titanium powders have been studied by means of dilatometry and Sintering diagram models.
Abstract: The sintering kinetics and mechanisms of micron-size and nanocrystalline titanium powders have been studied by means of dilatometry and sintering diagram models. An approximate particle-size range over which a transition in sintering mechanisms takes place has been identified. In the micron-size titanium powder, lattice diffusion from surface sources, and from sources on grain boundaries, are the operative mechanisms. The nanocrystalline titanium powder shows a continuous change in sintering mechanisms: (i) particle movement/dislocation movement at low temperatures, (ii) grain boundary diffusion up to moderate temperatures, and (iii) lattice diffusion and grain boundary rotation at higher temperatures.

TL;DR: In this paper, the authors used simple and composite frits for coating the titanium plates by enamelling and determined the fracture toughness and decrease the brittleness of the coating layers.
Abstract: Some vitroceramics belonging to the oxidic system SiO2-CaO-P2O5-B2O3-Na2O-K2O-Li2O-MgO-TiO2 were prepared and then characterised by optical microscopy and microhardness trials. The frits from the above mixture were turned into composite materials by reinforcing them with 0.1-0.8% in weight Ti powder. Both simple and composite frits were used for coating the titanium plates by enamelling. The vitroceramic layer-titanium couples were characterised by means of optical microscopy and microhardness trials. From hardness tests made at vitroceramic layer-metallic substrate interface adherence of the layer to the substrate was determined. By reinforcing the vitroceramic frits with titanium powder we tried to increase the fracture toughness and decrease the brittleness of the coating layers. These quantities were computed from Vickers microhardness values, indentation forces, measurements of the microhardness imprint diagonals and cracks that propagate from the imprint corners.

Abstract: This paper investigates the characteristic of single-layered and multi-layered compacts made by selective laser sintering using blended bimodal titanium powders. The surface texture and tensile strength were investigated by using single-layered compact. There were few defects in the surface of specimen sintered in vacuum, and the roughness was smoother than that of specimen sintered in argon. Maximum tensile strength of single-layered compact sintered in vacuum was about 200 MPa. The shrinkage and mechanical strength were investigated by using multi-layered compact. There was a unique tendency in the shrinkage of multi-layered compacts, which the density was around 76% and the adhesive bonding was not observed between layers, resulted in 70 MPa of maximum bending strength and 50 MPa of maximum tensile strength.
