Abstract:
Acicular ferrite has been used to increase the toughness and strength of low-carbon alloy steel weld metals. Finely dispersed nonmetallic inclusions can serve as nucleation sites for acicular ferrite, and thus reduce the grain size and consequently improve the mechanical properties of steel. [..]

Abstract:
Nowadays it is claimed that the silicon appears in the metal not only from the slag SiO2 reduction at the liquid phase, but also from a gaseous SiO. Presented in this paper, laboratory tests were aimed on finding the effect of temperature and MgO containing in the slag on the dynamics of the Si transition to the hot metal at the liquid phase at the time when slag lies on metal.

Abstract:
The influence of Temperature-Strain-Time parameters at the Thermomechanical Processing (TMP) of austenitic, duplex and pearlitic structural steels on the mesostructure formation has been studied based on the laboratory, industrial experiments and TEM analysis. The fragmented dislocation substructure observed in steels with a different carbon, nitrogen, titanium, niobium content as well as recrystallization gave evidence that TMP effects the work-hardening and softening behaviour.

Abstract:
Metal forming can be regarded as a process, during which materials are treated by “force” and “heating” under a certain external load and boundary condition (loading mode, rate of loading, constraint condition, geometry, contact friction condition, temperature field). Materials vary in formability and structure properties. [..]

Abstract:
Microstructure of the laboratory castings made from Fe-40at.%Al-Zr-B alloy was homogenized by the multi-pass hot rolling in protective capsules and subsequent lannealing. Based on the isothermal hot compression tests and EBSD analysis, the sufficiently accurate model describing the static recrystalization kinetics of the such prepared coarse-grained B2 iron aluminide after strain 0.2 was developed.

Abstract:
The increase of susceptibility to plastic forming of magnesium alloys may be achieved by lithium addition in the amount of up to 15 % of alloy mass. At the same time by introduction of lithium which has density of 535 kg/m3 a significant weight decrease of the alloy is achieved. [..]

Abstract:
The Al-Mn-Fe-Si-Zr alloy was twin-roll cast and a part of the material was after casting annealed at 450 °C for 8 hours in order to allow the precipitation of the Al3Zr phase. Both modifications were further processed by equal channel angular pressing (ECAP) at room temperature. [..]
