Fabrication and characterization of aluminium titanate and mullite added Porcelain ceramics
Akkus, Ahmet; Boyraz, Tahsin (KOREAN ASSOC CRYSTAL GROWTH, INC, 2019)In this study, aluminium titanate (AT, Al2TiO5) and mullite (M, 3Al(2)O(3)center dot 2SiO(2)) ceramics were synthesized by reaction sintering from Al2O3, SiO2 and TiO2 powders which consisted of homogenization by wet ball ... -
Investigation of wear properties of CaO, MgO added stabilized zirconia ceramics produced by different pressing methods
Akkus, Ahmet; Boyraz, Tahsin (KOREAN ASSOC CRYSTAL GROWTH, INC, 2018)Stabilized zirconia has superior high temperature properties such as high tolerance for thermal shock, low thermal conductivity, mechanical properties, elevated melting point, good phase stability and excellent oxidation ... -
The investigation of wear properties of different hard filling welding electrodes used in repair welding
Akkus, Ahmet (KOREAN SOC MECHANICAL ENGINEERS, 2018)The surface of tamping machine's digger is covered with a filler material because it is a material that is continuously used in TCDD (The State Railways of the Turkish Republic) lines and it is a material that needs to be ... -
NUGGET FORMATION EFFECTS IN RESISTANCE SPOT WELDED DIFFERENT STEEL SHEETS
Akkus, Ahmet (UNIV ZAGREB FAC MECHANICAL ENGINEERING & NAVAL ARCHITECTURE, 2017)In this study, galvanized and austenitic stainless steel sheets were joined to each other by using resistance spot welding. The thicknesses of the galvanized steel and austenitic stainless steel are 0.93 and 1.03 mm, ... -
Temperature distribution study in resistance spot welding
Akkus, Ahmet (NATL INST SCIENCE COMMUNICATION, 2009)This paper presents effect of sheet thickness and current density on cooling speed and temperature distribution in resistance spot welding. Thicker sheets have higher temperatures in weld zones. Temperatures are higher in ...
