Abstract:
Granulated blast furnace slag exhibits latent hydraulic properties and its binding properties can be evoked by the addition of the alkali activator. Subsequent hydration processes during the setting and hardening processes let to origination of the solid products with the mechanical properties comparable or even better than the product obtained with ordinary Portland cement.

Abstract:
The effect of the strain accumulation by changing the number of rolling passes on the rolling force, structure and mechanical properties of austenitic Cr-Ni-Ti stainless steel with different carbon contents has been studied. An increase of the number of passes for a given overall reduction was found to have a beneficial effect on tensile properties while maintaining adequate ductility. [..]

Abstract:
At the beginning of the production of body parts from Al-alloy, there was a requirement to experimentally verify its suitability for their production. This alloy is characterized by a combination of various stress-deformation properties influencing the non-uniform plastic flow of the material, especially during deep drawing of complex shaped drawn parts.

DOI: https://doi.org/10.37904/metal.2020.3471, 203-208
Abstract:
During forging, dies are subject to a complex load collective caused by combined thermally and mechanically induced stresses. Crack formation and deformation on tool surfaces, as a result of low fatigue resistance, lead to tool failure and high process costs. [..]

Abstract:
Folding is a common industry practice. In this work we have studied the influence of some parameters such as (the radius of curvature of the matrix, the coefficient of friction between the punch and the specimen, the play between matrix and punch, the thickness of the specimen and the mesh of the specimen) on the deformations of the different zones of the specimen, by a numerical simulation of U-bending using the ABAQUS calculation code.The studied parameters will prove to be of relevant use for the design of the parts from the metal sheets, through the bending forming process.

Abstract:
Research into new forming methods has yielded new techniques of altering the microstructure in hypereutectoid steels. An innovative approach to processing can lead to improved mechanical properties thanks to elimination of problematic and undesirable sharp-edged carbides which are very difficult to dissolve. [..]

Abstract:
This work is devoted to one of the most important problems of modern physics of strength and plasticity – to the behavior of metals under various conditions of intense external influences. These are large plastic deformations, the formation of nanocrystalline structures under these conditions, complex cooperative dynamic processes in the zones of deformation localization, low temperatures or high deformation rates, high-strength materials, etc. [..]
