“…Also, a numerical model was developed to study the influence of the biting force angle on the stress distribution developed in the lattice abutment. Numerical analysis showed that˛= 30 • is a critical biting force angle, at which the maximum equivalent stress increased noticeably (Jamshidinia, 2014).…”

“…In the next step, a bio-compatible dental implant could be developed by the combination of a root that mimics the natural tooth and a dental abutment with elastic micro-displacement. Jamshidinia et al (2014) extended the mentioned study and used the EBM® process to investigate the application of non-stochastic lattice structures for building a bio-compatible dental abutment. Three different lattice structures including cross, honeycomb, and octahedral structures with different unit cell sizes were employed to produce a lattice abutment made of Ti-6Al-4 V by EBM®.…”

Compression Behavior of Diamond Lattice Structure and Its Hall–Petch Relationship

et al. 2020

View full text Add to dashboard Cite

As the additive manufacturing (AM) technology improves, in particular the selective laser melting (SLM) advance, lattice structures made of Ti6Al4V become a new material and are applied in aerospace and medical field increasingly. It is essential to investigate the compression behavior and size effect in diamond lattice structure. Herein, a new analytical model based on elastic strain energy is presented for predicting the compressive properties of diamond lattice structure. The effective diameter De is put forward to improve the accuracy of prediction. In addition, the effects of unit cell size on the mechanical properties and energy absorption are investigated. The results show that first peak stress and elastic modulus can be predicted well by the analytical models. Through quantitative analysis, the relationships between mechanical properties and unit cell size in different relative density can be concluded as Hall–Petch relationships. In addition, the energy absorption increases with relative density and changes with the unit cell size.

Growth, Microstructure, and Mechanical Properties of Co–Cr–Mo Crystal Fibers Fabricated from the Melt by Unidirectional Solidification

et al. 2021

Many complicated forming processes are required to fabricate thin wires of Co–Cr–Mo (CCM) biomedical materials due to the poor workability of these materials. A novel fabrication technique for CCM crystal fibers is developed by unidirectional solidification directly from the melt using the alloy‐micro‐pulling‐down (A‐μ‐PD) method. Compared with conventional methods, the proposed technique is an innovative fabrication method for CCM alloy fibers and is characterized by low cost, time saving, and low loading. In addition, the proposed method shows potential for further thinning of fibers. At growth rates of 0.1 and 0.3 mm min−1, CCM single‐crystal fibers composed of the ε‐phase with a hexagonal close‐packed (hcp) structure (hcp ε‐phase) can be fabricated. The hcp‐ε‐phase CCM crystal fibers exhibit considerably improved strain because of the slipping line in the hcp structure. Moreover, the γ‐phase with an fcc structure (fcc γ‐phase) appears in the hcp‐ε‐phase at growth rates greater than 0.5 mm min−1, and the ratio of the fcc γ‐phase in the CCM crystal fibers systematically increases with an increase in the cooling rate. The results reveal that the growth rate in the A‐μ‐PD method has a notable effect on the fabrication of single‐ or polycrystalline CCM fibers.
