The molecules GeCu, GeCo, GeFe, and GeCr have been shown to exist in the vapor phase over liquid solutions of germanium and transition metal at temperatures above 1600K. Using …
The aim of the current study is to compare the effect of virtual and physical manipulatives on preschool children’s understanding of geometric shapes. A quasi‐experimental research …
This study aimed to optimize the chemical composition of wear- and corrosion-resistant Al 2 O 3 -TiO 2 composite coatings. 2-layered and 4-layered Al 2 O 3 -TiO 2 coatings were …
This study compares the effect of Augmented Reality (AR) based virtual manipulatives to physical manipulatives for teaching geometric shapes to preschool children to improve their …
Sol-gel fabricated TiO 2 –Al 2 O 3 bilayer coatings were deposited on 316L surfaces with several combinations of layers. Microstructural, corrosion, and wear features of the fabricated …
AISI H13 hot work tool steels were subjected to shallow and deep cryogenic treatment. One set of the samples was single tempered, while the other set was double tempered. Cooling …
In this study, AA7075 aluminum matrix composites reinforced with the combination of SiC, Al 2 O 3 , and B 4 C particles were fabricated by the liquid metal infiltration method. The effects …
Spheroidal graphite cast irons (SGCIs) have been commonly used in automotive and energy sectors where superior mechanical strength and wear resistance are required. This paper …
This study investigated residual stress evaluations during gaseous nitriding of 50CrMo4 and 31CrMoV9 steels. The nitriding processes were carried out in the NH 3 /H 2 /N 2 …
Nodular cast irons have been mainly used in automobile components exposed to large forces like brake pads, suffering from abrasion against recently developed lightweight Al 2 O 3 -…
