RISEffect of titanium addition on weld metal toughness in submerged arc welded HSLA pipeline steel
mixture of acicular ferrite, grain-boundary ferrite, bainite, martensite
and microphases. Therefore, the mode of fracture also changed from ductile to quasi-cleavage
and cleavage. Also, the observed increasing of titanium content...
Evaluation of potential of high Si high C steel nanostructured bainite for wear and fatigue applications
Effect of titanium addition on the chemical composition and toughness of weld metal in a submerged arc welded HSLA pipeline steel
, the microstructure was changed from a mixture of acicular ferrite, grain-boundary ferrite, Widmanstätten ferrite to a mixture of acicular ferrite, grain-boundary ferrite, bainite and ferrite with M/A microconstituent. Therefore, the mode of fracture also changed from...
The change in the chemical composition and toughness of API 5L-X70 welds by addition of titanium
of titanium content, the microstructure was changed from a mixture of acicular ferrite, grain-boundary ferrite, Widmanstätten ferrite to a mixture of acicular ferrite, grain-boundary ferrite, bainite and ferrite with M/A microconstituent. Therefore, the mode...
A Novel Process on Production of Thin Wall Austempered Ductile Iron Heat-treated in the Mold
and the structure was only composed of bainitic-ferrite and high carbon retained austenite....
Carbide Precipitation in the Microstructures of Austempered Ductile Irons Containing 0.48% and 4.88% Al
of specimens of different composition have been made by green sand casting and gravity die casting. The transformation to a bainitic microstructure during austempering under different conditions was then examined for the most successful of the experimental...
The Bainite Transformation and the Carbide Precipitation of 4.88% Aluminium Austempered Ductile Iron Investigated Using Electron Microscopy
The transformation to a bainitic microstructure during austempering under different conditions was examined for the most successful of the experimental casts. Austenitising temperature of 920C and austempering temperatures of 350C for different...
A novel process on production of thin wall austempered ductile iron heat-treted in the mold
resulted in no
trace of martensite and the structure was only composed of bainitic-ferrite and high carbon
retained austenite....
The Microstructural Characteristics of Al-alloyed Ductile Irons Austempered at 400°C for 100 min
number of irons of different composition have been made by green sand casting and gravity die casting of appropriate design to provide the experimental materials. The transformation to a bainitic microstructure during austempering under different...
The Effect of Cooling Rate on Bainite Phase Formation in Austempered Nickel-Molybdenum Gray Cast Iron
Taking into account the importance of the amount of bainite phase on the microstructure of cast irons and its influence on the improvement of mechanical properties, this research selected an alloy of gray cast iron containing Nickel...
