Abstract:
The cold roll bonding (CRB) of aluminium alloys to steel is a key industrial manufacturing process tool used to generate bimetallic composites for engine components. By joining steel and aluminium alloys in the solid state the desired mechanical bearing properties of both metals can be achieved; thus allowing for the superior tribological wear and strength characteristics observed in modern automotive bearings.

Abstract:
The investigations into the hydromechanical bulge forming involved the use of copper tubes at the relative ratio so/D=0.04 (where so is the wall thickness and D is the tube diameter). The experimental results of bulge forming of axisymmetric components are presented. [..]

Abstract:
The development of deformable magnesium alloys and plastic forming methods has been strongly limited so far. Plastically worked magnesium alloys are very rarely used due to technological difficulties in plastic working and to high production costs. [..]

Abstract:
Modern technology of bar rolling in many cases is based on the application of single or multiple longitudinal slitting, so-called Slit Rolling (SR). The slitting process uses special passes and guides to prepare, shape and separate the incoming billet into two or more individual strands, which will then be further rolled into finished sizes. [..]

Abstract:
Simulation of the stress-strain state of the rolls with the active and the passive experiments needed to determine the stresses, strains and displacements of rolls of finishing stands UWRM -1700 used for the construction of the shape of the active generatrix of profiled work rolls needed to improve the profile and flatness hot rolling mills.
The main deformation of four-roll systems is sag and elastic compression of the support and work rolls. Key influence on the quality of hire has a value of deflection of the work roll.
The object of research is rolls of finishing stands of UWRM-1700 of JSC "ArselorMittal Temirtau". [..]

Abstract:
Test of wire by alternate bending to rupture is specific in that only a very small part of the sample is at this test exposed to plastic deformation. Thanks to this, the test result, it means the number of bends to rupture, depends strongly on the wire area, which was affected by bending. [..]

Abstract:
High-grade medium-carbon steel C45 with content of carbon 0.42 – 0.50 % and manganese 0.50 – 0.80 %, intended for hardening and tempering, has been often used for production of die forgings and the less exposed machine components. The hot stress-strain curves of this steel were investigated by uniaxial compression tests using the Hot Deformation Simulator HDS-20 within a wide strain range (up to 1.0). [..]
