“…In order to reduce the number of aggregated and thus, increase the number of isolated TiO 2 NPs, several improvements were considered: (1) initial TiO 2 NP commercial powder was intensively ground and subsequently sonicated in 5 times diluted suspensions (6.6 mg L −1 ); and (2) TiO 2 NPs were suspended using opaque vials to avoid the agglomeration of TiO 2 favoured by UV light absorption. 35 Surprisingly, blocking such absorption was crucial to improve the suspension stability of TiO 2 , which resulted in a much more homogeneous p-HAp interface decorated by TiO 2 NPs instead of agglomerates. These results are discussed in the next section.…”

The constitutive relationships between stress, strain rate, and temperature were analyzed to obtain a unified description of creep and plasticity of aluminum alloys produced by powder metallurgy and of aluminum-based metal-matrix composites. As both classes of materials are characterized by the existence of a threshold stress ( 0 ), a unified description of creep (low strain-rate regime) and plasticity (high strain-rate regime) was obtained by substituting the conventional power-law equation with the sinh relationship, where the applied stress is replaced by the difference between the applied stress and a threshold stress. The stress exponent was n ϭ 3 or 5, and the activation energy was equivalent to the activation energy for self-diffusion or to the activation energy for diffusion of solute elements in the matrix. The model was applied to an unreinforced alloy (2014PM) and a composite (6061 ϩ 20 pct Al 2 O 3 ) tested in tension (under constant load) or torsion (at constant strain rate) in the temperature range between 300 ЊC and 500 ЊC. The results were compared with data available in the literature.
