Çalışma kapsamında gaz atomize titanyum ve sünger titanyum tozları, mekanik öğütme cihazında 20:1 bilya / toz oranı kullanılarak 30 dak öğütülmüştür. Öğütülen tozlar 630 MPa basınç altında soğuk preslenmiştir. Üretilen numuneler 1200 °C’de 2 saat atmosfer (argon) kontrollü fırında sinterlenmiştir. Sinterlenen numuneler fırın ortamında oda sıcaklığına soğutulmuştur. Karakterizasyon çalışmalarında toz boyut analizörü, optik mikroskop, tarama elektron mikroskobu (SEM) ve transmisyon elektron mikroskobu (TEM) kullanılmıştır. Yapılan çalışmalar sonucunda öğütme sonrası her iki malzemede toz şekilleri ve boyutları, başlangıç tozlarına göre farklılık göstermişlerdir. Optik mikroskop incelemelerinde sünger titanyumdan üretilen parçalarda gözenek miktarının gaz atomize titanyum tozundan üretilen parçalara göre daha fazla olduğu belirlenmiştir. Ayrıca gaz atomize titanyum ve sünger titanyumun optik mikro yapıları incelemelerinde sıkı paket hegzagonal kristal yapılı α titanyum fazının oluştuğu belirlenmiştir.", "language": "tr", "english_title": "Characterization of Mechanical Milled Sponge Titanium and Gas Atomized Titanium Powders", "english_abstract": "In this work, mechanical milled gas atomized titanium and sponge titanium materials have been characterized. For the experimental work, gas atomized titanium and sponge titanium powders were milled using a 20: 1 ball / powder ratio for 30 minutes in a mechanical alloying device. The milled powders were cold-pressed under 630 MPa pressure. Compressed samples were sintered at 1200 °C for 2 hours under argon atmosphere. Sintered samples were cooled to room temperature in the furnace environment. The sintered alloys were characterised by using optic and scanning electron microscope (SEM), transmission electron microscopy (TEM) and laser particle sizer. As a result of the studies, the powder forms and dimensions of the two materials after grinding have varied according to the starting powders. In the optical microscope studies, it was determined that the amount of pore in the parts produced from sponge titanium was higher than that of gas atomized titanium powder. In the study of the optical microstructures of titanium and sponge titanium with gas atoms, it was determined of hexagonal closed packed α titanium phase was formed in both structures.", "doi": null, "doi_url": null, "resource_url": "https://www.set-science.com/a/77971485-d7ae-4b1f-bf31-345b0812eb36", "pdf_url": "https://www.set-science.com/a/77971485-d7ae-4b1f-bf31-345b0812eb36/pdf", "og_image": "https://www.set-science.com/assets/img/og-card-v2.png", "authors": [ { "public_id": "d25be1a9-a717-4b53-944c-7a6da812f497", "given": "Ijlal ", "family": "Şimşek  ", "full": "Ijlal  Şimşek  ", "literal": null, "orcid": null, "orcid_url": null, "email": "dozyurek@karabuk.edu.tr", "corresponding": false, "sequence": "first", "affiliations": [ { "name": "Karabük Üniversitesi  ", "department": null, "country": null, "country_code": null, "ror": null, "ror_url": null } ] }, { "public_id": "fb05760c-ad3e-4553-a759-713b2c988a5d", "given": "Doğan", "family": "Şimşek", "full": "Doğan Şimşek", "literal": null, "orcid": null, "orcid_url": null, "email": "dozyurek@karabuk.edu.tr", "corresponding": false, "sequence": "additional", "affiliations": [ { "name": "Bitlis Eren Üniversitesi  ", "department": null, "country": null, "country_code": null, "ror": null, "ror_url": null } ] }, { "public_id": "776d6ad9-c55c-4143-92dc-3249107e272e", "given": "Dursun ", "family": "Özyürek  ", "full": "Dursun  Özyürek  ", "literal": null, "orcid": null, "orcid_url": null, "email": "dozyurek@karabuk.edu.tr", "corresponding": true, "sequence": "additional", "affiliations": [ { "name": "Karabük Üniversitesi  ", "department": null, "country": null, "country_code": null, "ror": null, "ror_url": null } ] } ], "keywords": [], "translations": [ { "language": "en", "title": "Characterization of Mechanical Milled Sponge Titanium and Gas Atomized Titanium Powders", "abstract": "In this work, mechanical milled gas atomized titanium and sponge titanium materials have been characterized.
