Study of Methods to Reduce Water Loss Rate for Vegetables in Vacuum Cooling

Zhileng xuebao, 2013
Water loss is inevitable during vacuum cooling because the temperature is decreased through the loss of water in vegetables. The cooling effect of leafy vegetables in vacuum cooling is evident, but that of root vegetables is not obvious because their ...

CO cooling rates - Revised calculations

The Astrophysical Journal, 1988
The steady state cooling rates for collisionally excited CO have been recalculated using recent cross sections of Schinke et al. (1985) and Flower and Launay (1985). Despite large differences in particular rate coefficients, it is found that the original calculations of McKee et al.

Geometric Optimization and Mechanical Performance Enhancement of Auxetic Structures for High‐Impact Applications Through Fused Deposition Modeling

Advanced Engineering Materials, EarlyView.
This study explores the mechanical performance of three auxetic structures, identifying a re‐entrant‐star hybrid as the most effective for impact absorption. Finite element simulations and experiments demonstrate significant gains in energy absorption and flexural strength after geometric optimization. This study investigates the mechanical performance

Dynamic Precipitation during High‐Pressure Torsion of a Magnesium–Manganese Alloy

Advanced Engineering Materials, EarlyView.
An ultrafine‐grained alloy is produced by high‐pressure torsion of solutionized Mg–1.35 wt% Mn. Precipitation of nanometer‐scale Mn particles during deformation provides pinning sites. This prevents the formation of a bimodal grain structure and results in a finer grain size than for pure Mg.

Laser Metal Deposited Ti4822 Hollow Pipe: Experimental and Computational Modelling Study

Advanced Engineering Materials, EarlyView.
Laser metal deposition (LMD) of a crack‐free built Ti4822 alloys is challenging. This article reports outstanding characteristics of a hollow pipe that is built with LMD technology when a predicted, nontransformation substrate temperature of 800 °C is used.

Understanding the Effect of Resistance Temperature Detector Temperature Controllers on Microstructural Alignment in Magnetic Freeze Casting

Advanced Engineering Materials, EarlyView.
The effect of temperature controllers that are commonly used in freeze‐casting is investigated in this work. Temperature controllers are observed to generate a voltage in the slurry. Microstructural alignment and ultimate compressive strength data show this voltage to interfere with the ability to align the microstructure using magnetic fields ...

Effect of cooling rate in the mid-temperature region on fatigue crack propagation rate of bainitic steel

Journal of Materials Research and Technology
Controlling continuous cooling is an important means to control the most important mechanical properties of bainitic steel for frogs in railroad applications. In this paper, a bainitic steel for railway frogs is taken as the research object. By designing

Cooling Rates in Hot-Poured Bituminous Sealants

Transportation Research Record: Journal of the Transportation Research Board, 2006
The performance of bituminous sealants applied to cracks and joints is partly governed by installation. An important installation parameter yet to be investigated is the sealant rate of cooling after it is poured hot. Cooling rates affect sealant microstructure and rheology, adhesion at the sealant–hot-mix asphalt interface, and the time during which ...

Exploring Microstructure–Physical Property–Corrosion Response Relationship in Intermetallic Compounds of Al‐Cu Bimetallic Interfaces

Advanced Engineering Materials, EarlyView.
Al‐Cu intermetallic compounds (IMCs) have a significant influence on the properties of Al‐Cu bimetallic interfaces formed in compound casting. This article provides a deeper understanding of microstructure, crystallography, thermal properties, hardness, and corrosion response of Al‐Cu IMCs with the goal of facilitating the optimization of the ...
