Abstract:
Complex concentrated alloy (CCA) with nominal composition (CoCrFeNi)92.5Al3Ti4.5 (in at.%) was prepared by vacuum induction melting in a ceramic crucible and tilt cast into the cylindrical ceramic mould. The alloying elements such as Al and Ti were added to the basic quaternary CoCrFeNi system to promote the formation of L12 phase in the FCC (face - centered cubic) matrix during heat treatments. [..]

Abstract:
Nondestructive testing is an important part of any production process that is required to ensure the quality of materials and parts. The development of reliable nondestructive testing (NDT) methods applicable to novel materials and manufacturing processes such as additive manufacturing is a challenging task because of the complex geometry and anisotropic material properties.

Abstract:
In this work, the dynamic material modelling (DMM) is employed to identify the hot working window that is suitable for hot processing of Duplex stainless steel 2205 (DSS). The Gleeble 1500 thermo-mechanical simulator was used to conduct the investigation, where several hot compression tests were conducted at a temperature range of 850 - 1050 °C and strain rates of 0.001s-1 - 5s-1.

Abstract:
Weld microstructure depends on the characteristics of welded materials and parameters of welding technology, especially on the heat input that determines the peak temperature and the cooling rate. When the coated sheets are welded, the effect of the chemical composition of the coating must be also considered even though its thickness is only a few tens of microns. [..]

Abstract:
Hot-work tool steels are extensively used in industrial applications that require high resistance to mechanical and chemical degradation at elevated temperatures. To meet these requirements, hot-work tool steels must exhibit good mechanical properties, including high tensile strength, hardness, wear resistance, and tempering resistance, as well as high thermal conductivity and ductility.

Abstract:
One of the methods of evaluating the mechanical properties of a material in the case of its limited amount l is the use of techniques that employ the miniaturized test specimens. The basic properties used mostly for residual life evaluation are tensile strength, impact notch toughness or impact notch toughness transition curve, fracture toughness, creep and high cycle fatigue.

Abstract:
Steel 16Mo3 (P1 according to ASTM) represents still a popular material used in waterwalls, pipelines and other components of steam power plant boilers operating at temperature up to 530 °C. However, the absence of other alloying elements (especially chromium) reduces the long-term structural stability of this steel especially at temperatures higher than 450 °C. [..]
