Abstract:
Small punch test is an advantageous method for evaluation of mechanical properties of components especially in cases, where it is technically difficult or even impossible to obtain enough bulk material for standard tests. Therefore, the method is very well applicable in power industry, for example in residual lifetime assessment of critical parts of components and structures after long-term operation. [..]

Abstract:
The presented research was focused to optimize the conditions in a T-shaped three-strand tundish to minimize the intermix zone during steel casting. The intermix zone occurs when different steel grades are cast in a single sequence without interruptions or restarts, resulting in mixing of old and new steel grades in the tundish and the continuous cast billet.

Abstract:
The identification of the wear mechanism of the refractory lining of the basic oxygen furnace is a prerequisite for the optimization of the steelmaking process. Knowledge of the way in which a given factor acts on the amortization of the refractory lining is closely related to the development of technological procedures serving to limit their influence. [..]

DOI: https://doi.org/10.37904/metal.2023.4682, 84-88
Abstract:
One of the factors influencing the surface quality of castings is the resulting thermal expansion when silica sands are used. This is characterised both by its high value compared to other non-silica sands, and by its typical discontinuous behaviour, leading in many cases to defects such as veining or increased surface roughness, which further lead to increased costs of processing the castings or, in extreme cases, to scrap pieces.

Abstract:
This research article introduces a methodology for studying the operational wear of experimental shaped parts of moulds for high-pressure die casting (HPDC) of zinc alloys. The study includes roughness analysis and geometric dimensioning and tolerancing (GD&T) based on a coordinate measuring machine (CMM) and 3D scanning to quantify the wear of the mould parts due to contact with the zinc alloy melt and solidifying castings during the HPDC process cycles.

Abstract:
Achieving a balance between strength, toughness and technological properties of cast iron requires knowledge of the relationships between local and macroscopic failure processes. High toughness is conditional upon the substantial dissipation of deformation energy during crack propagation and the initiation of ductile failure. [..]
