Nondestructive Testing of Welded Composite Metal Foams

Advanced Engineering Materials, EarlyView.
X‐ray computed tomography (CT) is used to evaluate welded steel–steel composite metal foam (CMF) joints of two density classes. It reports variation in postweld spatial void distribution and correlates it to weld‐induced changes, mechanical performance, and failure within welded CMF panels.

Numerical study of parametric effects on heat transfer deterioration of supercritical CO2/DME mixture flowing in a horizontal tube

Case Studies in Thermal Engineering
Compared to using pure CO2 as a working fluid, mixing CO2 with dimethyl ether (DME) in specific ratios can enhance heat transfer efficiency and reduce system operating pressure. However, the issue of heat transfer deterioration (HTD) in supercritical CO2/

Influence of Surface Finish on the Tribological Performance of AlTiBN Coatings Deposited on Forming Tools

Advanced Engineering Materials, EarlyView.
Aluminum and nitride coatings are used in industry because they are hard, resist wear, and protect against oxidation. Adding boron can improve friction behavior and other properties. This study tests coatings on surfaces with different finishes. Results show smoother surfaces perform better, while rough ones wear faster, although coatings can reduce ...

On the evaluation of dryout conditions for a heat-releasing porous bed in a water pool

, 2019
This work is motivated by the problem of restraining temperature escalation inside a porous heat-releasing media submerged in a pool of liquid coolant. When coolant temperature reaches saturation, boiling begins in the bulk of the porous bed, with void ...
