Investigation of microstructure and mechanical properties of friction stir welded dissimilar St37/St52 joints
(Institute of Physics Publishing, 2019)
Although friction stir welding (FSW) has widely been applied to aluminum alloys in several industries over the past three decades, it is not yet used in industry for joining of steels. The aim of this study is to characterize ...
Determination of seasonal metal concentrations in seawater of the Iskenderun Bay in the eastern Mediterranean, Turkey
(Parlar Scientific Publications, 2019)
In this study, seasonal variations of some heavy metal concentrations (Fe, Zn, Cd, Cu, Co, Ni, Al, Mn, Pb, and Cr) were determined. A total of 108 seawater samples were taken in three different stations with depths of about ...
Thiadiazoloquinoxaline and benzodithiophene bearing polymers for electrochromic and organic photovoltaic applications
(Taylor & Francis Ltd, 2019)
Two novel thiadiazoloquinoxaline and benzodithiophene (BDT) bearing copolymers were designed and synthesized. Different BDT units (alkoxy and thiophene substituted) were used as donor materials and the effect of alkoxy and ...
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 ...
