The ship is safest when it is in port, but that's not what ships were built for. ABSTRACT Due to coming emission legislations, the temperature is expected to increase in heavy-duty diesel engines, specifically in the hot-end of the exhaust system affecting components, such as exhaust-and turbo manifolds. Since the current material in the turbo manifold, a ductile cast iron named SiMo51, is oper...

Selective laser melting (SLM) as an additive manufacturing method makes it possible to quickly produce complexly shaped three-dimensional (3D) metal specimens from a powder. This work describes how SLM affects the surface phase composition of 3D printed specimen, analyzed with conversion electron Mössbauer spectroscopy (CEMS), X-ray (CXMS) and diffraction (XRD). Both stainless 1.4404 (CL20ES) s...

In sheet metal forming (SMF), deformation is caused by the relative movement between and tool, which generates friction forces. However, materials behave differently during plastic deformation. this study, a tribo-simulator was designed to investigate effect of different contact conditions or formability tests on tribological behavior AISI 304 430 stainless-steel sheets. The effects texture mic...

Lead-cooled fast reactors (LFRs) are considered one of the most promising technologies to meet requirements introduced for advanced nuclear systems. LFRs have higher neutron doses, temperatures, burnup and an extremely corrosive environment. The failure studies claddings play a vital role in improving safety criteria promoting research on materials. This paper presented comprehensive review ext...

Oxide scale formation during short-term annealing and electrolytic pickling behavior of ferritic EN 1.4622 austenitic 1.4828 stainless steels are investigated. The is performed at temperatures between 1000 1100 °C for 1200 steel grade under humid atmospheres in simulated industrial process. Neutral pickling, also referred to as neutral electrochemical or the Ruthner Neolyte Process, Na2SO4 elec...

A time-dependent neutronics analysis for the HIBALL reactor is presented. The helium to dpa ratio in the ferritic steel structure is found to be sensitive to neutron spectrum softening. The microstructure calculations show that helium diffusivity is a sensitive function of vacancy accumulation from one pulse to the next. A strong coupling exists between the three components of damage: helium, v...

austenitic stainless steels are extensively used in various applications requiring good corrosion resistance and formability. in the current study, the formation of nano/ ultrafine grained austenitic microstructure in a microalloyed aisi 304l stainless steel was investigated by the advanced thermomechanical process of reversion of strain-induced martensite. for this purpose, samples were subjec...
