NANOBAİNİTİC TRANSFORMATİONS İN LOW ALLOYS STEELS

Electrochemical formation of Al-Sc alloy in molten salt Polat, Çağlar; Karakaya, İshak; Department of Metallurgical and Materials Engineering (2019) Al-Sc alloys have better mechanical properties in comparison to commercial aluminum alloys. The aim was to produce Al-Sc alloys containing at least 2wt % scandium by electrochemical reduction of the byproducts such as ScF3 or the alternative compounds obtained from hydrometallurgical processing of low grade lateritic nickel in this thesis. Electrochemical production of Al-Sc alloy in pure molten CaCl2 and CaCl2-NaCl mixtures was studied for this purpose. The graphite-liquid aluminum-CaCl2 or CaCl2-NaCl inte...
Synthesis of TiB2-reinforced iron-based composite coating YILMAZ, SEVAL; Ozenbas, M.; YAZ, Mehmet (Elsevier BV, 2009-08-01) Titanium diboride (TiB2) particulate reinforced Fe-based alloy composite coating was produced with ferrotitaniurn (FeTi), ferroboron (FeB), ferrotungsten (FeW), ferrochromium (FeCr), ferrovanadium (FeV) and ferromolybdenum (FeMo) powders by using gas tungsten arc welding (GTAW) process. The effects of GTAW processing on the microstructure of AISI-4340 alloy coating with ferro-alloy powders were investigated experimentally. Abrasive wear tests were performed on the coated surface of samples to examine the in...
Potential of High Compressive Ductility of Ultrafine Grained Copper Fabricated by Severe Plastic Deformation Asano, Mayu; Yuasa, Motohiro; Miyamoto, Hiroyuki; Tanaka, Tatsuya; Erdoğan, Can; Yalçınkaya, Tuncay (2020-11-01) Severe plastic deformation (SPD) can fabricate high-strength materials by forming an ultrafine grained (UFG) microstructure. Low elongation to failure of UFG materials in tensile tests, which has often been regarded as a measure of ductility of materials, has been attributed to low strain hardening of UFG structures where dislocation slip and its accumulation is very limited. In the present work, it is shown that the compressive extensibility of UFG materials can be comparable or potentially superior to tha...
Mechanical behavior of metallic glass / HCP nanolayered coatings Özerinç, Sezer; Motallebzadeh, Amir (null; 2019-09-01) Introduction/Purpose High hardness, large elastic limits and grain-boundary free structure of metallic glasses (MG) make them promising materials for wear resistant, corrosion resistant and biocompatible coatings [1]. However, the brittle nature of MGs in monolithic form is a major disadvantage. MG/crystalline nanolayered composites can overcome this problem by impeding the catastrophic propagation of shear bands [2]. Most studies so far on these nanocomposites have focused on MG/FCC crystalline structures ...
Replaceable links with gusseted brace joints for eccentrically braced frames Bozkurt, Mehmet Baku; Topkaya, Cem (Elsevier BV, 2018-12-01) Various replaceable link details were developed for use in steel eccentrically braced frames (EBFs) during the past decade. These details include but are not limited to bolted flush end-plated links, bolted extended end-plated links, web connected replaceable links, and bolted flange- and web-spliced links. Another detail which is based on splicing the beam outside the link and braces was recently proposed by the authors. The performance of this detail when used with directly connected braces was studied th...
