Main reason for the current losses in electrolytic magnesium production is the
reaction between electrode products. Present study was devoted to effective
separation of chlorine gas from the electrolysis environment by a new cell design
and thus reducing the extent of back reaction between magnesium and chlorine to
decrease energy consumption values. The new cell design was tested by [...]

With constant miniaturization of integrated circuits, the current densities experienced in interconnects in
electronic circuits has been multiplied. Aluminum, which is widely used as an interconnect material, has
fast diffusion kinetics under low temperatures. Unfortunately, the combination of high current density and
fast diffusion at low temperatures causes the circuit to fail by electromigration (EM), which is the [...]

Abstract: The consumption of high speed tool steels used as cutting tool materials in
conventional turning lathes are quite high. The aim of this work is to investigate the
cutting and wear behavior of a high speed tool steel that can be used as cast without
rolling and to characterize its microstructure. Alloy is designed with a chemical
composition [...]

Main purpose of this study was to find the optimum conditions to produce a
charge material for ferromanganese production or steelmaking with high content of
iron and manganese carbides from Denizli-Tavas manganese ore by carbothermic
reduction and investigate the effects of temperature, time, amount of active carbon
addition and CaO addition on this reduction.

This aim of this thesis is to examine the possibility of using Magnetic
Barkhausen Noise (MBN) technique in characterizing the microstructures of
quenched and tempered low alloy steels as well as annealed low carbon
steels. To determine the average grain size by MBN, SAE 1010 steel
consisting of dominantly ferrite was used. The specimens were slowly cooled

In this study, hydrogen induced cracking (HIC) behavior of welded steels
used in petroleum lines under sour petroleum environments was
investigated. The testing environment in NACE TM0284-2003 standard was
used in order to simulate sour petroleum environment.

Microstructural and mechanical characterizations of heat treatable Al-Mg-Si-Cu
based wrought aluminum alloys have been studied. The aim of this work was to
produce fine grained, high strength alloy by adjusting processing conditions:
deformation, solutionizing and aging.

The purpose of this study was to investigate the effects of mold temperature, initial resin
temperature, and the vacuum, applied at resin exit ports, on the mechanical properties of
epoxy matrix woven glasss fiber reinforced composite specimens produced by Resin
Transfer Molding (RTM).

Titanium-nickel is a unique class of material known as Shape Memory Alloy
(SMA). A thermoelastic martensitic phase transformation is responsible for its
extraordinary properties such as shape memory effect and superelasticity. The
near equiatomic Ti-Ni alloys are the commercially most exploited SMAs because
of the unique combination of these properties and superior ductility, strength,
fatigue resistance and corrosion resistance. The [...]
