Purpose: In this work was presented the cooling rate influence on microstructure of the Zn-Al cast alloy. This research work presents also the investigation results of derivative thermoanalysis performed using the UMSA device. The material used for investigation was the ZnAl4Cu1 alloy. Design/methodology/approach: Moreover the analysis of cooling rate influence on the derivative curve changes was...
Purpose: The aim of this work was to improve the properties of the surface layer of the MCMgAl12Zn1 cast magnesium alloy. This improvement can be achieved by modification of surface layer microstructure by melting and simultaneous feeding the silicon carbide particles into the weld pool. Design/methodology/approach: Laser alloying of the MCMgAl12Zn1 magnesium alloy with the silicon carbide was carried...
Purpose: Paper presents results of investigations with two layers explosively formed sandwich composite consisting of different composition joint which requires very often knowledge of structure and mechanical properties. These properties are connected with microstructure that is influenced by technological factors under cladding. Design/methodology/approach: The sample bars were prepared from explosively...
Purpose: of this paper is evaluation of behaviour of plasma nitrided layers subjected to influence of internal and external hydrogen. Properties of nitrided layers like: hydrogen permeation and trapping, fracture mode, and plasticity were examined. Design/methodology/approach: Structural low-alloy steel was nitrided at glow discharge in the gas mixture of various N2, H2, and Ar content. Samples with...
Purpose: The aim of the paper was to determine the effect of deformation-induced martensite on the microstructure, mechanical properties and corrosion resistance of X5CrNi18-8 austenitic steel. Design/methodology/approach: The investigations included observations of the microstructure on a light microscope, researches of mechanical properties in a static tensile test, microhardness measurements made...
Purpose: The purpose of this paper is application of statistical models in tribological properties simulation of composite materials based on porous ceramic preforms infiltrated by liquid aluminium alloy. Design/methodology/approach: The material for studies was produced by a method of pressure infiltration of the porous ceramic framework. In order to investigate the influence of reinforcing phase's...
