Final step of rail manufacturing is cold rolling straightening process and it hassignificant effects on mechanical properties, straightness, flatness and development of residualstresses. Measurement of residual stresses after straightening process is obligated by railmanufacturing standards. In the present investigation, an attempt has been made to evaluateresidual stresses after straightening ...
the effect of niobium on the formation of nanostructured low carbon steel using martensite treatment
the formation of nano/ultrafine grained ferrite in low carbon steels containing different amounts of niobiumwas investigated using thermomechanical treatment which consisted of annealing of 85% cold rolled martensite with different parameters. the specimens were characterized by optical and scanning electron microscopy and vickers hardness test. a lamellar dislocation cell structure was formed ...
The large difference in mechanical properties and plastic deformation ability of each layer will have a great impact on the overall performance composite sheet prepared by cold-roll bonding. effect rolling material variables stress distribution bonding state zone should be studied. In this work, an accurate cold-rolling model considering anisotropic position-dependent friction is established us...
The Interstitial Free (IF) grade steel sheets are used for auto body applications where these sheets require good formability/drawability property. To achieve this property the cold rolled sheets are annealed to obtain desirable texture in the recrystallised grains to avoid material failure during forming operation. The paper deals with an ultrasonic technique to determine the condition of the ...
The properties and cost have made the Nickel-Titanium (NiTi) shape memory alloys (SMA) attractive for a variety of applications wherein shape memory effect (SME) / superelasticity (SE) and biocompatibility are important. Anisotropy of the shape recovery associated with shape memory effect strongly depends on the type of r 30 minutes in air) Ti-Rich Ni-Ti SMA (Ni51at%Ti) when subjected to cold r...
304 stainless steels (SS) were considered as the materials for a dry storage canister. In this study, ER (Electrode Rod) 308L was utilized as the filler metal for the groove and overlay welds of a 304L stainless steel substrate, which was prepared via a gas tungsten arc-welding process in multiple passes. The electron backscatter diffraction (EBSD) map was used to identify the inherent microstr...
Cast AZ31B-H24 magnesium alloy, comprising Mg with 3.27 wt% Al and 0.96 wt% Zn, was cold rolled and subsequently annealed. Global texture evolutions in the specimens were observed by X-ray diffractometry after the thermomechanical processing. Image-based microstructure and texture for the deformed, recrystallized, and grown grains were observed by electron backscattered diffractometry. Recrysta...
