Farklı bor kimyasalları ile borlanmış Inconel 625 alaşımının karakterizasyonu
(Pamukkale Üniversitesi Mühendislik Bilimleri Dergisi, 2017)
Bu çalışmada, nikel bazlı süper alaşımlar içerisinde endüstride yaygın olarak kullanılan Inconel 625 alaşımı 3 farklı borlama tozu ile borlanmıştır. Kullanılan borlama tozları, %90 elementel nano bor tozu + %10 NaBF4 (NB), ...
Determination of Barreling of Aluminum Solid Cylinders During Cold Upsetting Using Genetic Algorithm
(UNIV FED RIO DE JANEIRO, LAB HIDROGENIO, 2019)
This study presents Genetic Programming models for the formulation of barreling of aluminum solid cylinders during cold upsetting based on experimental results. The maximum and minimum radii of the barreled cylinders having ...
Effects of blanking speed on the shear surface of mild steel (St37)
(Polish Academy of Sciences, 2016)
Blanking operation is widely used to cut sheet or plates by a shearing process between punch and die. The process of shearing and the conditions of the sheared surface are influenced by the punch, the die, the speed of ...
Microstructural, wear and corrosion characteristics of boronized AISI 904L superaustenitic stainless steel
(Elsevier, 2021)
AISI 900 series stainless steels are considered as low-cost alternatives to nickel-based superalloys used for highly corrosive environments. However, in terms of mechanical properties, they have average strength and hardness ...
Characteristics, high temperature wear and oxidation behavior of boride layer grown on nimonic 80A Ni-based superalloy
(Elsevier, 2021)
Nickel-based superalloy Nimonic 80A was pack-borided in a solid medium at temperatures of 850 degrees C and 950 degrees C for 2 h and 4 h using silicon-free boriding powders. To investigate the effects of the boriding ...
Microstructure and mechanical properties of borided CoCrFeNiAl0.25Ti0.5 high entropy alloy produced by powder metallurgy
(Elsevier, 2021)
CoCrFeNiAl0.25Ti0.5 high entropy alloy alloys (HEA), produced by powder metallurgy were subjected to boriding to improve their mechanical properties. Sintering was carried out at 1200 degrees C for 2 h in Ar, and boriding ...

Nickel-based superalloy Nimonic 80A was pack-borided in a solid medium at temperatures of 850 degrees C and 950 degrees C for 2 h and 4 h using silicon-free boriding powders. To investigate the effects of the boriding ...
Effect of thermal degradation on the properties and wear behavior of Cr−V−C composite coatings grown on ductile iron
(Elsevier, 2021)
The thermal fatigue behavior of chromium vanadium carbide (Cr - V - C) coatings and the wear of the coatings after thermal fatigue cycling was studied. The Cr - V - C coatings were grown on the surface of a ductile iron ...
Microstructure, some mechanical properties and tribocorrosion wear behavior of boronized Al0.07Co1.26Cr1.80Fe1.42Mn1.35Ni1.10 high entropy alloy
(Elsevier, 2021)
High-entropy alloys (HEAs) with face-centered cubic (FCC) structures exhibit high toughness and corrosion resistance, but their average strengths and relatively low wear resistance can limit their engineering ap-plications. ...
