CHARACTERIZATION AND MECHANICAL PROPERTIES OF PM Fe-Cu/SiCp ALLOYS
Oksuz, Kerim Emre; Gun, Tarik; Simsir, Mehmet (TRANS TECH PUBLICATIONS LTD, 2014)Fe-Cu-Co alloys are the new generation of metal matrix for diamonds in PM processed cutting tools. These alloys were created with the purpose of reducing the cobalt content in diamond tools. Nevertheless, little have been ... -
Effect of chill formation on the mechanical properties and microstructure of grey and nodular cast irons used in automotive industry
Subutay, Halit; Simsir, Mehmet; Aydin, Murat; Karaca, Bahadir (PAMUKKALE UNIV, 2016)Cam shafts used in automobiles are produced by cast iron (grey cast iron, nodular cast iron) or steel. In this study, effect of chill formation on the surface of grey and nodular cast irons is investigated on the wear ... -
Effect of heat treatment on fracture behavior of steel-wire-reinforced gray cast iron
Simsir, Mehmet (SPRINGER, 2008)In this experimental study, fracture toughness of heat-treated metal matrix composite was investigated. The gray cast iron was reinforced with steel wire of volume fraction of V(r) = 0.05 and three-point bend specimens ... -
Fracture behavior and microstructure of steel fiber reinforced cast iron
Simsir, Mehmet (SPRINGER, 2007)In this study, improvement of fracture toughness and strength of gray cast iron by reinforcing steel fiber was investigated. Three point bend specimens were used to calculate the flexural strength and fracture toughness. ... -
Impact toughness and microstructure of continuous steel wire-reinforced cast iron composite
Akdemir, Ahmet; Kus, Recai; Simsir, Mehmet (ELSEVIER SCIENCE SA, 2009)In this study, improvement of impact toughness of gray cast iron by reinforcing steel fiber was investigated. The composite material was produced by sand mould casting technique. Then, normalizing heat treatment was applied ... -
An investigation into stainless-steel/structural-alloy-steel bimetal produced by shell mould casting
Simsir, Mehmet; Kumruoglu, Levent Cenk; Oezer, Ali (ELSEVIER SCI LTD, 2009)Bimetal consisting of stainless steel (316L) and structural steel (30CrNiMo8) was produced by shell mould casting technique and interface region between two metals was characterized by metallographic examination and ... -
Investigation of the tensile properties of continuous steel wire-reinforced gray cast iron composite
Akdemir, Ahmet; Kus, Recai; Simsir, Mehmet (ELSEVIER SCIENCE SA, 2011)The aim of the present study was to improve the tensile properties of gray cast iron by reinforcing the material with a steel wire. The composite was produced by sand mold casting, and the specimens were normalized by ... -
Investigation of the wear behavior of B4C reinforced Fe/Co matrix composites produced by hot press
Simsir, Mehmet; Oksuz, Kerim Emre; Sahin, Yusuf (ELSEVIER SCIENCE BV, 2011)Diamond tools are widely used for sawing, drilling and grinding materials. The extreme hardness of diamonds and the strength of the diamond/matrix combination make these tools superior. In this experimental study, diamond ... -
Investigation on the machinability of steel/steel laminates by CO2 laser
Simsir, Mehmet; Ozer, Ali; Kumruoglu, Levent Cenk (INDERSCIENCE ENTERPRISES LTD, 2014)In this study, an experimental investigation of machinability of steel/steel laminates using CO2 laser was presented. O-2 assist gas was used for cutting of laminates. Laser power and feed rate were changed gradually as ... -
Mechanical and microstructural properties of low-carbon steel-plate-reinforced gray cast iron
Avci, Ahmet; Ilkaya, Nevzat; Simsir, Mehmet; Akdemir, Ahmet (ELSEVIER SCIENCE SA, 2009)In the present experimental study, strengthening of gray cast iron by reinforcing with steel plates was investigated in the as-cast and normalized conditions. Normalizing heat treatments were applied to the specimens at ... -
Optimization of selective leaching of Zn from electric arc furnace steelmaking dust using response surface methodology
Kul, Mehmet; Oskay, Kursad Oguz; Simsir, Mehmet; Subutay, Halit; Kirgezen, Habip (ELSEVIER SCIENCE BV, 2015)The aim of this work is to investigate and optimize the effects of the leaching parameters on the selective leaching of zinc from electric arc furnace steelmaking dust (EAFD). The response surface method was applied on the ...
