Precipitation sequence in niobium-alloyed ferritic stainless steel
Niobium is an important alloying element in the design of heat-resistant ferritic stainless steels for automotive exhaust systems. When in solid solution, it improves both the high temperature strength and the resistance to thermal fatigue. However, it also forms several kinds of precipitates during service. These reactions have been modelled, taking into account the multicomponent nature of th...
متن کاملOn the Constitutive Model of Nitrogen-Containing Austenitic Stainless Steel 316LN at Elevated Temperature
The nitrogen-containing austenitic stainless steel 316LN has been chosen as the material for nuclear main-pipe, which is one of the key parts in 3rd generation nuclear power plants. In this research, a constitutive model of nitrogen-containing austenitic stainless steel is developed. The true stress-true strain curves obtained from isothermal hot compression tests over a wide range of temperatu...
متن کاملExternal corrosion resistance of steel and ferritic stainless steel exhaust systems
The exhaust system has a number of requirements to fulfil. The major ones are to reduce the noise level created by the engine, to channel the waste gases out the rear of the automobile, to minimize the reduction in engine performance, and to have an acceptable service life and cost1. The exhaust system is divided into two main parts, the hot end and the cold end. The components comprising the h...
متن کاملMicrostructural Evolution of Roll Bonded Al-Clad Stainless Steel Sheets at Elevated Temperatures
The cold roll bonding of Al on AISI 304L stainless steel was carried out to fabricate the Al/304L/Al clad sheet composites. The maximum bond strength of 20 N/mm was acquired just by 38% reduction, for which the tearing of the aluminum sheet occurred during the peeling test. The microstructural evolution during subsequent postannealing heat treatment was systematically studied based on the impur...
متن کاملQuantification of ridging in ferritic stainless steel sheets by electron backscattered diffraction R-value maps.
In ferritic stainless steel (FSS), undesirable surface defects of ridging appear during deep drawing. The formation of these defects is attributed to the inhomogeneous distribution of orientations of individual grains. In the present work, a new electron backscattered diffraction R(α)-value map was introduced, and the dependence of the tensile directions on the formation of ridging in an FSS sh...
