Küçültülmüş Tambur Testi ile Demir Cevheri Peletleri Aşınma Dayanımı Belirlenmesi
Sivrikaya, Osman; Arol, Ali İhsan (null; 2019-04-19)
The tumbling-abrasion indices of iron ore pellets are measured according to instructions in ASTM E279- 97 (2010). This test measures the resistance of the product pellets under certain abrasive condition in a standard test drum. However, this test requires 11.3 kg pellet to carry out a single tumbling-abrasion test. This amount of pellet can be obtained from industrial-scale pellet production. However, it is impossible to produce this amount of pellet in laboratory-scale investigation since the capacities o...
Determination of shot peening effect on fatigue behavior of AISI 4140 steel by non-destructive measurement of surface residual stresses
Çalışkan, Salim; Gür, Cemil Hakan; Department of Metallurgical and Materials Engineering (2018)
The fatigue performance of aircraft parts can be improved by inducing compressive residual stresses in the near-surface zone by shot-peening. The depth profile and the magnitude of residual stresses depend on the shot peening parameters. Aircraft industry requires an easy and rapid non-destructive method for determination of residual stress state to verify the achievement of the desired results of shot-peening. This study aims to determine nondestructively the residual stresses at the surface by the Magneti...
Determination of residual stress state in SAE/AISI 8620 carburized steel by non-destructive testing methods
Kaleli, Tuğçe; Gür, Cemil Hakan; Department of Metallurgical and Materials Engineering (2017)
Industrial performance of the carburized steels is mainly dependent on the residual stress state in the carburized layer that is controlled by the process parameters such as carburizing temperature and time. Non-destructive evaluation of the material properties and residual stress state has been gained importance for industrial applications due to its advantages such as measurement speed and complete control possibility of the components by automation. The aim of this thesis is to investigate the efficiency...
Determination of heavy metal concentration in feed and permeate streams of polymer enhanced ultrafiltration process
Muslehiddinoglu, J; Uludağ, Yusuf; Ozbelge, HO; Yılmaz, Levent (1998-08-01)
Polymer enhanced ultrafiltration (PEUF) is a newly developed method for the removal of heavy metals from aqueous solutions. This method was applied for the removal of mercury and cadmium with the presence of polyethyleneimine (PEI) as a water soluble polymer. After ultrafiltration experiments for metal-polymer mixtures, two separate streams, namely, retentate and permeate, former of which contains mainly metal-polymer complex and free polymer molecules while latter of which mainly contains free metal ions, ...
