Simulation modelling of cold rolled metal strip by asymmetric technology

Microstructure and mechanical properties of cold rolled, annealed HSLA strip steels

A large testing programme of a strip steel grade, microalloyed by vanadium, titanium and niobium, was conducted. The experiment was based on combination of cold rolling, recrystallization annealing, mechanical testing, metallographic examinations, SEM and TEM analyses. Samples in the form of stripes with dimensions of 3.9×25×500 mm were rolled in several passes with the total height reduction o...

Fatigue and Anisotropic behaviours of cold rolled AA1200 Aluminium Alloy

This study examines the fatigue and anisotropy behaviour of cold rolled AA1200 aluminium alloy for light weight automotive connecting rod application. Aluminium (Al) 1200 ingots were melted at temperature of 680 0C (after one hour of heating) cast in sand mould and cast samples homogenized for 6 hrs at 480 0C. The cold rolling process was carried out after homogenisation for 10, 20, 30, 40 and ...

Modelling and Simulation of Metal Cutting by Finite Element Method

Vanadium in Cold-rolled Sheet Steels

In hot rolled products, which are the subject of other presentations here, vanadium has been used for many years in high strength products, often in combination with other microalloying additions such as niobium or titanium. Vanadium can provide important contributions via both precipitation strengthening and ferrite grain refinement (due to austenite conditioning during thermomechanical proces...

Kinetics of individual grains during recrystallization of cold-rolled copper

The formation of a recrystallization texture is closely related to the nucleation and growth of recrystallizing grains, which may vary from grain to grain. Cube texture is a commonly observed recrystallization texture in face centered cubic metals of medium to high stacking fault energy after heavy cold-rolling and annealing. In this work, recrystallization of pure copper cold-rolled to a von M...
