In this paper, based on the as-cast CuSn10P1 alloy. Semi-solid alloy billet was prepared by cold-rolled isothermal treatment strain-induced melting activation (CRITSIMA). The effects of cold-rolling reduction, temperature, and time microstructure semi-solid copper were studied metallographic microscope Image-Pro Plus software. changes primary elements in analyzed briefly a scanning electron (SE...

A precise prediction of the rolling force is critical to ensure quality final product, especially in cold thin strips. Based on this, a new mathematical model developed work out when considering roll crossing angle and shifting values at speed ratios 1.1, 1.2 1.3. An iterative method was used indicate contact area shape, from which automatically calculated using Matlab™ code for cases cross ang...

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 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 ...
