Estudio de la solidificación de recubrimientos de acero rápido M2 obtenidos por Laser Cladding

Revista de Metalurgia, 2013
Los recubrimientos de acero rápido por Laser Cladding (LC) son complejos porque aparecen fisuras y la dureza es menor a la esperada. En este trabajo se han fabricado recubrimientos de acero AISI M2 sobre acero al carbono AISI 1045 y tras el procesado por

Strong Lead‐Free Bioinspired Piezoceramics for Durable Energy Transducers

Advanced Functional Materials, EarlyView.
We fabricated brick‐and‐mortar lead‐free piezoceramics with Bi0.5Na0.5TiO3 monocrystal platelets as bricks and amorphous silica as mortar. The alignment of the bricks and the presence of the amorphous silica led to anisotropic residual stresses. These residual stresses increase the samples toughness, strength and durability while the brick alignment ...

Covalent Functionalization of 2D Semiconductors: A Roadmap to Advanced Electronic Devices

Advanced Functional Materials, EarlyView.
This Review presents recent advances in the covalent functionalization strategies for two‐dimensional semiconductors and their implementation in modern technologies. Layered materials are modified through diverse molecular chemistries (e.g., thiols, diazonium salts, alkyl halides, and electron‐deficient species) to tailor their surface properties ...

Nano‐Architected Metallic Metamaterial With Enhanced Fatigue Resistance via Dislocation Starvation

Advanced Materials, EarlyView.
Nanoscale Ni single crystals exhibit remarkable fatigue resistance over an order of magnitude higher than that of bulk single crystals through dislocation starvation. By translating this mechanism into geometric nano‐architecture, nano‐architected Ni single‐crystal metamaterials achieve about twice the fatigue resistance of the bulk, despite their ...

EBSD analysis of the microstructure during static and metadynamic recrystallisation of austenitic stainless steel

, 2015
The importance of controlling the microstructure of stainless steels during industrial process is twofold: on one hand, it defines the key properties of the semi-finished products, and on the other hand it affects the strength and formability of ...

Crystallographic Orientation, Recrystallization, and Texture Development in AZ91 Magnesium Alloy Rods Fabricated by Continuous Rotary Extrusion (CRE) [PDF]

Archives of Metallurgy and Materials
The magnesium alloy AZ91 is widely used in the aviation and automotive industries, where high mechanical properties combined with low density are required. Searching for new, advanced deformation methods in these industries is also essential.

Direct Growth of 2D Bilayers on Au(111) for Low‐Coercive Sliding Ferroelectricity

Advanced Materials, EarlyView.
Controlled CVD growth of stacking‐defined bilayer ReS2 on Au(111) enables parallel‐stacked bilayers with intrinsic sliding ferroelectricity, a strong piezoelectric response, and an ultralow coercive voltage. Atomic‐resolution imaging and in situ measurements further reveal the decisive role of clean interfaces in achieving low‐barrier ferroelectric ...

Interaction between Microalloying Additions and Phase Transformation during Intercritical Deformation in Low Carbon Steels

Metals, 2019
Heavy gauge line pipe and structural steel plate materials are often rolled in the two-phase region for strength reasons. However, strength and toughness show opposite trends, and the exact effect of each rolling process parameter remains unclear.

Lithography‐Compatible Conductive Metal–Organic Frameworks for Scalable Electronics

Advanced Materials, EarlyView.
Conductive MOF thin films are integrated as gate electrodes in semiconductor devices through a photolithography‐compatible patterning strategy. CVD‐grown 2D MOF thin films enable stable operation across bottom‐gate MoS2/MoTe2 field‐effect transistors and top‐gate IGZO arrays, highlighting the potential of conductive MOFs as functional electronic ...
