Effect of Welding Parameters on the Liquation Cracking Behavior of High-Chromium Ni-Based Superalloy
Mashhuriazar, Amirhossein; Omidvar, Hamid; Gür, Cemil Hakan; Sajuri, Zainuddin (2020-11-01)
Gas turbine blades working under extremely harsh operating conditions are made of superalloys. These superalloys are exposed to various damage mechanisms, which wear them out gradually. Welding is often preferred to repair the damaged components for cost minimization. This study aimed to investigate the effects of flexural load, heat input, and welding speed on the weldability and intergranular liquation cracking of high-chromium Ni-based superalloy. For this purpose, a series of Sigmajig tests designed bas...
Effect of Support Width on Stress Resultants in Ring Beams Interacting with Silo Shells
Topkaya, Cem (2019-09-20)
Elevated cylindrical metal silos are often supported on a ring beam which rests on discrete column supports. The ring beam plays an important role in redistributing the majority of the discrete forces from the column supports into a more uniform stress state in the cylindrical wall, which is necessary to reduce the potential for buckling of the shell wall. Traditional design treatments for ring beams assumed that the ring is supported by knife‐edge supports and is under the action of a uniformly distributed...
Effect of storage time on mechanical properties of extended-pour irreversible hydrocolloid impression materials
ŞAHİN, VOLKAN; Jodati, Hossein; Evis, Zafer (Elsevier BV, 2020-07-01)
Statement of problem. Recent commercial extended-pour irreversible hydrocolloid impression materials (EPIHIMs) claim to maintain dimensional stability up to 120 hours. However, data regarding their mechanical properties and performance after 120 hours of storage are lacking.

Effect of the Cu Alloying on the Precipitation Behavior of Al-Mg-Si Alloys
Özer, Seren; Dericioğlu, Arcan Fehmi (null; 2018-10-27)
In the present study, the effect of varying amounts of copper (Cu) addition on the kinetics of the precipitation behavior of heat treatable 6000 series Al-Mg-Si alloys have been investigated by means of scanning electron microscopy (SEM), differential scanning calorimetry (DSC), X-ray diffraction (XRD) and Vickers microhardness measurements. Presence of Cu can greatly enhance the mechanical properties, particularly strength and hardness by refining the precipitate distribution and increasing the stability o...
