Weld repair is a common technique to remove defects in the weldments. However, particularly in the high strength low alloy steels (HSLA), heat input during weld repair causes complex changes in the microstructure and mechanical properties. In this study, the influences of repeated heat input and thermal cycle upon repair weld on the microstructure and mechanical properties of the welded joints of API 5L X65 were investigated via optical microscopy, scanning electron microscopy; Charpy-V impact, Vickers hardness, and tension tests. The results were analyzed and evaluated for enhancement of strength and toughness of the repaired pipeline steels.

Determination of welding parameter dependent hot cracking susceptibility of 5086-h32 aluminium alloy with the use of mvt method
Batıgün, Caner; Ankara, Osman Alpay; Department of Metallurgical and Materials Engineering (2005)
Hot cracking is a serious problem that encounters during welding of aluminium-magnesium alloys. In the present study, solidification and liquation type of hot cracks in weld metal and the heat-affected zones of 5086-H32 aluminium alloy were investigated by using Modified Varestraint Test (MVT) with TIG-AC and TIG-DC welding. With determining the size, type and number of cracks, a relation was established between welding line energy and strain on the hot crack formation. This information was used to determin...
Effect of Oil Feed Groove on Compressor Piston Lubrication
Hacıoğlu, Bilgin; Dursunkaya, Zafer (2008-07-14)
Oil feed grooves are implemented in reciprocating compressor piston applications to assure a constant supply of lubricating oil on bearing surfaces and decrease friction loss. In a hermetically sealed compressor, due to small clearances encountered, oil supply becomes critical in order to prevent the boundary lubrication. Due to the small size of the piston and small piston–cylinder clearance, a partial lubrication regime is present. In the current study, a model that solves Reynolds’ equation for piston-cy...
Effect of lay-up orientation on fracture toughness of CFRP laminates
Yavuz, Burak Ogun; Çöker, Demirkan; Parnas, Kemal Levend (2018-12-01)
Delamination in advanced composites, which causes reduction in the laminate strength, has been a continuing problem. Since it is relatively easier to manufacture, the general practice for the fracture toughness is to conduct tests with 0//0 interface and use these experimental values in the analyses. However, the fracture toughness values are known to vary for different angle interfaces. This happens to be a significant issue in the case of impact. When interlaminar properties of only 0//0 interface is used...
Effect of differential lubrication on the cup drawing of mild steel blanks
Atala, H. (Elsevier BV, 1990-7)
Cup-drawing test have been performed on mild steel blanks to study the frictional behaviour of the flanges in a cup-drawing operation, by utilizing differential lubrication. Molybdenum disulphide paste has been chosen as the lubricant because of its good performance in preliminary trials. The results suggest that lubrication of the flange is essential in the achievement of a fully drawn cup without failure and without wrinkles. It can also be stated that lubricant application to central regions appears to b...
Effect of retrogression and reaging heat treatment on corrosion fatigue crack growth behavior of AA7050 alloy
Akgün, Nevzat; Gürbüz, Rıza; Department of Metallurgical and Materials Engineering (2004)
The effect of retrogression and reaging heat treatment on corrosion fatigue crack growth behavior on AA7050 T73651 aluminum alloy is investigated. CT (Compact Tension) specimens are prepared in LS direction for fatigue crack growth tests . Samples are solution heat treated at 477 °C and aged at 120 °C for 24 h (T6 condition). After that, samples are retrogressed at 200 °C for times of 1, 5, 30, 55 and 80 minutes in a circulating oil bath. Then, samples are re-aged at 120 °C for 24 h (T6 condition). Hardness...
