Among these methods, there is a direct casting method which is also divided into upward vertical casting and horizontal casting. Cu-Mg alloy is one of the copper alloys produced by continuous casting which has not been widely studied and which has interesting properties such as high conductivity with good tensile strength, excellent weldability and excellent plateability. In this study, the effect of horizontal continuous casting parameters on the microstructures, mechanical properties and electrical conductivity on the Cu-Mg alloy rod was investigated. Pulling distance and pause time were gradually changed during the manufacturing of the Cu-Mg alloy rod. The evolution of the cast rod microstructure was studied by optical microscopy and scanning electron microscopy. The texture in cast copper alloy was analyzed by electron backscatter diffraction technique. The chemical composition was measured by energy dispersive spectroscopy. The mechanical properties of the cast rod were determined by hardness measurements. Electrical conductivity was measured with an eddy current conductivity meter. It has been found that the grain size and their distribution vary with the casting parameters. Columnar and fine grains were observed in the same cast metal which gave higher hardness in fine grain areas and low electrical conductivity.</strong>2023-12-31T00:00:00+00:00Copyright (c) 2023 Turkish Journal of Materialshttp://scienceliterature.com/index.php/tjom/article/view/10-14Mechanical and Microstructural Investigation of Dissimilar S235 and S32205 Steel Sheets After TIG Welding2024-01-08T07:31:57+00:00Aziz Barış Başyiğitabbasyigit@kku.edu.trAli Güla-298@hotmail.comHalil İbrahim Kurthiakurt@gmail.com<p><strong>S235 unalloyed steels are broadly used in structural and constructional applications while UNSS32205 duplex stainless steel alloys are preferred especially in bridges, marine and pulp, paper production industries. These two distinct types of steel alloys can be both used in applications especially for economical considerations assuming that high alloyed UNS S32205 steel is more expensive as compared to S235 alloy. These alloys can be joined together with fusion welding operations such as Tungsten Inert Gas Welding technique. Welding of these alloys are referred as white and black welding technique as a result of white and black designating stainless and low alloyed steels respectively. In this study, S32205 and S235 steel sheets both having thicknesses of 3mm were joined by TIG welding with pure argon shielding gas. Micro-structural investigations, micro-vickers hardness and tensile tests were made on raw materials and welded joints. As tensile and micro-vickers hardness tests are both considered, dissimilar welded joints exhibited close hardness and strength values with raw materials. </strong></p>2023-12-31T00:00:00+00:00Copyright (c) 2023 Turkish Journal of Materialshttp://scienceliterature.com/index.php/tjom/article/view/15-21An Overview of Additive Manufacturing Technologies and Materials2024-01-08T07:31:57+00:00Raziye KILIÇraziyekilic@atauni.edu.tr<p><strong>Additive manufacturing is defined as a manufacturing method that makes it possible to produce parts layer by layer. AM encompasses a wide range of materials with cross-industry applications and a variety of processes. Various AM techniques such as VAT Photopolymerization, Material Extrusion, Binder Jetting, Powder Bed Fusion, Sheet Lamination, Directed Energy Deposition, Material Jetting are used in conjunction with different types of materials. Plastic, metal, ceramic and composite materials can be processed using these techniques. In contrast to conventional manufacturing processes, AM offers advantages such as design freedom, rapid prototyping and personalized production. This technology is considered one of the keys to industrial transformation as it offers flexibility in the production of complex structures, optimization of parts and mass production. This study looks at additive manufacturing technologies, the different materials used and the wide range of applications for this technology. The enormous potential that additive manufacturing offers can lead to revolutionary changes in all industries, and this study serves as a reference source for understanding these transformations.</strong></p>2023-12-31T00:00:00+00:00Copyright (c) 2024 Turkish Journal of Materials
