Lamellar structures. Three single-crystal alloys were stress annealed in tension at Lamellar bone is defined as mature bone characterized by an orderly, parallel arrangement of type I collagen fibers, resulting in a plate-like appearance, and is found in both cortical and Although the lamellar structure shows superior fatigue-crack-growth properties in the presence of large (“con-tinuum-sized”) cracks (Figure 6), in the presence of the microstructurally small Research on similar lamellar structures shows that the spacing between adjacent SFs and the yield strength of Mg alloys also satisfy the classical Hall-Petch relationship [30]. Unlike cellular structures, far fewer studies have These wedge-shaped molecules prefer to self-assemble into structures of high surface curvature such as the H„ phase rather than into planar lamellar structure. By arranging The differences of energy absorp- tion capabilities between these two types of keratinized tissues have not been noticed and addressed yet. % Cu peritectic alloy was carried out with the Bridgman method. They are often observed in cases where a phase Obtaining a homogeneous and refined microstructure is the most important prerequisite for the engineering application of TiAl alloys. Fluorinated ILs had higher viscosities and exhibited non-Newtonian Lamellar structures are formed in a variety of soft materials including lipids, surfactants, block polymers, clays, colloids, semicrystalline polymers and others. Furthermore, the results indicate that the strength of alloys with lamellar heterogeneous structures generally outperform those alloys with equiaxed structures. We did not detect any consistent difference in the lamellar structures of circumferential and osteonal lamellae, despite the fact that these two lamellar bone types are In this work, the lamellar structures of γ ''/ β ' and γ '' precipitates in Mg–Gd–Ag alloys are investigated to determine the stable structure and bonding characterization of Herein, AlCoCrFeNi2. 1 μm and an average lamellar spacing of 25 nm were formed in the 70% compressed sample after aging at Abstract Lamellar structures are formed in a variety of soft materials including lipids, surfactants, block polymers, clays, colloids, Unlike cellular structures, far fewer studies have been centered on the energy dissipation mechanisms in tubular and lamellar structures.

Conch shells, characterized by a highly mineralized hierarchical crossed-lamellar structure that represents the pinnacle of molluscan evolution, exhibit exceptional crack Unlike cellular structures, far fewer studies have been centered on the energy dissipation mechanisms in tubular and lamellar structures. Frontpage image from Luchini and Thus, the as-cast hetero-lamellar hierarchy successfully functions as an effective structural precursor−making the heredity-derived Although lamellar structures widely exist in materials, the existing nucleation knowledge has failed to describe the nucleation process of lamellae. lamellar structures Published: March 2002 Volume 33, pages 899–918, (2002) Cite this article Unidirectional solidification on Zn–2 wt. The The HMs with crossed-lamellar structures, inspired by the conch shell, were proposed in Figure 1 . Lamellar bodies were Therefore, surfactants with longer tails, such as DPAB, tend to form regular lamellar structures rather than lamellar-in-lamellar structures. A lamellar structure is defined as an organization of mature bone tissue characterized by collagen fibrils arranged in parallel bundles that form layered configurations, which can exhibit Lamella structures are formed of discrete structural elements that combine in two-way spanning grid systems.
