Investigations on machinability of Al2O3 reinforced Al6061 metal matrix composites
(Süleyman Demirel Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2016)
In this study, six different MMCs containing Al6061 matrix and Al2O3reinforcements with particle sizes of 32 µm and 66 µm and weight fraction of 10%, 15% and 20% were produced using the vortex method. Machinability ...
Investigation on wear mechanisms of boronized AISI 4140 steel
(Scibulcom Ltd., 2017)
In this study, AISI 4140 steel was subjected to box boronizing treatment at 1123 K, 1173 K and 1223 K for 2h, 4h, and 6h with commercially EKabor 2 powders. Friction and wear behaviour of the boronized and following worn ...

Experimental Verification of Cell Shape-Collapse Relationships in Metallic Foams by Photoelasticity Method
(Gazi University, 2019)
In the present study, the effect of cell morphology on mechanical properties in metallic foams with Al based closed cells was examined. AlSi8Mg0.8 alloyed metallic foam materials were produced by the Powder Metallurgy (PM) ...
Characterization of atomic layer deposition coated cutting tools by X-ray photoelectron spectroscopy and examination of cutting performance
(Taylor & Francis Inc, 2019)
The performance of cutting tools was examined, involving synthesis of a 10 nm thin film of Aluminum oxide using atomic layer deposition. Characterization of coated and uncoated cutting tools was done by several methods. ...
Updated database, new empirical and theoretical values of average L shell fluorescence yields of elements with 23 <= Z <= 96
(Pergamon-Elsevier Science Ltd, 2020)
In this paper, a summary of existing experimental data published in the period of time between 1954 and 2015 is reviewed and presented in a tabular form for average L shell fluorescence yields taken from different sources. ...
High temperature wear behavior of the surface-modified externally cooled rolls
(Elsevier, 2018)
Externally cooled rolls of a steel plant were coated using three different surface modification techniques, namely titanizing, boronizing and borotitanizing. The grown coatings were examined using optical microscopy, ...
Properties and Corrosion Resistance of AISI H13 Hot-Work Tool Steel with Borided B4C Powders
(Korean Institute of Metals and Materials, 2019)
Abstract: In this study, the surface of AISI H13 steel was borided with powder blends of B4C and NaBF4 using the powder-pack method at 800, 900 and 1000 °C for 2, 4 and 6 h. The structural and mechanical characteristics ...
Experimental and theoretical study of ultraviolet-induced structural/optical instability in nano silicon-based luminescence
(American Institute of Physics Inc., 2018)
Nano silicon is emerging as an active element for UV applications due to quantum confinement-induced widening of the Si bandgap, amenability to integration on Si, and less sensitivity to temperature. NanoSi-based UV ...
