Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Seleção de genótipos de pessegueiro F1 com baixa necessidade de frio hibernal Selection of F1 peach genotypes with low chilling requirements

Revista Brasileira de Fruticultura, 2009
A baixa necessidade de frio é característica fundamental para que se possa cultivar economicamente o pessegueiro em condições de clima subtropical, devendo ser este, portanto, o principal objetivo dos programas de melhoramento nestas regiões.

In Situ Micromechanical Study of Bimodal γ′–γ″ Precipitate Assemblies in Ni–Cr–Al–Nb Superalloy

Advanced Engineering Materials, EarlyView.
A Ni–Cr–Al–Nb superalloy with a bimodal γ′–γ″ precipitate distribution is developed. Composite precipitate assemblies form through heterogeneous nucleation, effectively impeding dislocation motion. Micropillar compression reveals high strength at room and elevated temperatures, governed by precipitate shearing, with coupled faulting mechanisms ...

Molecular Dynamics Studies of Shape Memory Polymers: From Bead–Spring Models to Atomistic Simulations

Advanced Engineering Materials, EarlyView.
Coarse‐grained (left) and atomistic (right) models of the shape memory polymer ESTANE ETE 75DT3 are shown schematically. The two representations bridge molecular detail and mesoscopic description. Both models capture shape memory behavior, linking segmental mobility and conformational relaxation of anisotropic chains to macroscopic recovery, and ...

Precipitation Simulations of the O‐Phase in Ti2AlNb Alloys Processed by Laser Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
Simulated and experimental evolution of the O‐phase volume fraction during postprocessing of a Ti‐21Al‐25Nb (at.%) alloy processed by laser powder bed fusion. With results of sensitivity to input parameters from a thorough and quantified analysis, the interfacial energy matrix/precipitate is the most relevant input parameter for the simulation of the O‐

Energy Conservation Using Variable-speed Chilled Water Pumps for Single-loop Chilled Water Systems with Fan-coil Units

Energy Engineering, 2003
ABSTRACT This article addresses the need to reduce energy consumption by chilled water pumps in air conditioning systems. In particular, this article considers the use of variable-speed pumping systems. Many office buildings in China utilize air conditioning systems with fan-coil units (FCUs) and a primary/secondary chilled water system without ...
