During Laser Powder-Directed Energy Deposition (LP-DED), many complex phenomena occur. These phenomena, which are strictly related to the conditions used during building process, can affect quality of parts in terms microstructural features and mechanical behavior. This paper investigates effect parameters on microstructure tensile properties AISI 316L stainless-steel samples produced via LP-DE...

Abstract The influence of microstructural defects on the corrosion resistance AISI 316L additively manufactured with Metal Binder Jetting in high Cl - environments were studied herein. A comprehensive metallographic examination was conducted to identify followed by a study electrochemical techniques aim finding correlations between impurities microstructure and preferential nucleation sites. De...

Kobalt esaslı süper süperalaşımların da kullanıldığı gaz türbini ve roket motor parçalarının üretiminde, yüksek sıcaklık oksidasyon dirençleri nedeniyle benzer olmayan metallerin kaynağına ihtiyaç duyulmaktadır. Gaz tungsten ark kaynağı (TIG), Lazer (LW), Elektron ışını (EBW) Plazma (PAW) gibi ergitme kaynak işlemleri, uygulamaları için yaygın olarak kullanılmaktadır. Kaynaklı birleştirmelerde ...

Abstract NIST SRM 1155a is an AISI 316L stainless steel (Cr18–Ni12–Mo2) and Standard Reference Material (SRM) intended for use with test methods elemental analysis. In a previous paper “Measurement of thermophysical properties solid liquid steel”, we already published reliable high temperature the phase this material such as dependent enthalpy, density electrical resistivity, well specific heat...

In the present study, compositionally-graded structures of AISI 316L and CoCrMo alloy are manufactured by powder-based laser-beam directed energy deposition (DED-LB). Through a process-integrated adjustment powder flow, in situ alloying two materials becomes feasible. Thus, sharp smooth transition with mixture both alloys can be realized. order to investigate phase formation during alloying, si...

Potentiodynamic polarization and impedance tests were carried out on 316L stainless steel with culturing murine fibroblast L929 cells to elucidate the corrosion behaviour of 316L steel with L929 cells and to understand the electrochemical interface between 316L steel and cells, respectively. Potential step test was carried out on 316L steel with type I collagen coating and culturing L929 cells ...
