Use of SEM and EDS analysis in the investigation of Al-Si-Cu piston alloy cast porosity [PDF]

open access: yesMetalurgija, 2009
Porosity formation was detected in the casting thinnest section in the proximity of the as cast surface and near the wall centerline. In order to investigate the cause of the porosity formation light microscopy was used to define as cast structure. After

SCANNING ELECTRON MICROSCOPY: AN ESSENTIAL TOOL IN THE INVESTIGATION OF CEMENT FOR OIL WELLS

open access: yesQuímica Nova
Oil well cementing plays a critical role in ensuring zonal isolation, structural integrity, and long-term well safety. Due to exposure to high pressures, temperatures, and chemically aggressive environments, understanding the microstructural behavior of ...

Effect of modification by Pt and manufacturing processes on the microstructure of two NiCoCrAlYTa bond coatings intended for thermal barrier system applications [PDF]

open access: yes, 2010
Few studies have already shown that Pt influences the diffusion of aluminium and therefore the microstructure of β-NiAl or γ-Ni/γ′-Ni3Al materials. Besides, several works have revealed that the addition of Pt to MCrAlY (M = Ni and/or Co) improves the ...

Low‐Cost, Large‐Scale Nanoporous Metals by Mechanical Alloying, Oxide Reduction, and Dealloying of Powders

open access: yesAdvanced Engineering Materials, EarlyView.
Powder metal processing provides scalable advantages in nanoporous (np) metal development. Mechanical alloying is used to produce unique precursors for hybrid nanopore formation by oxide reduction and dealloying. As demonstrated in np Ag, this approach improves process efficiency while promoting smaller ligaments and larger pores, both of which are ...
