Abstract: The paper presents the results of investigation into the effect of structure banding on the mechanical and technological properties of finished wire rod. It describes also the causes of the formation of banding and the possibility of reducing it by changing the thermoplastic working parameters. [..] Read more

Abstract: The effect of tempforming temperature on the microstructure and mechanical properties, especially impact toughness, of the S700MC-type high-strength low-carbon steel was investigated. Tempforming at temperatures of 923 and 973 K was characterized by the development of ultrafine-grained layered microstructure consisting of grains highly elongated in the rolling direction with the transverse grain size of 530 and 920 nm, respectively.

Abstract: The steel wires are used as strand core for phase conductors in electrical distribution network. The mechanical properties of these wires are tested by tensile strength, twist and winding tests before production of conductors. [..] Read more

Abstract: TWIP steels are steels with a good combination of strength and plasticity. Their application should be relevant in case of critical parts of car bodies. [..] Read more

Abstract: Welding is one of the so-called special processes that require verification to ensure correct execution in sufficient quality. Low-quality weld is not satisfying the requirements for in-service operation, either due to presence of defects (e.g. [..] Read more

Abstract: Currently, quality control in modern enterprises is one of the factors creating the principles of organization and functioning of enterprises.
