Purpose: In this paper there is presented the corrosion behavior of cast magnesium alloys in as cast state and after heat treatment. Design/methodology/approach: The following results concern scanning electron microscopy investigations in the SE as well BSE observation mode, for better phase contrast results, also qualitative microanalysis was applied for chemical composition investigations of the...
Purpose: The aim of the paper is to determine the influence of hot-rolling conditions on structure of new-developed high-manganese austenitic steels. Design/methodology/approach: Flow stresses during continuous and multi-stage compression tests were measured using the Gleeble 3800 thermo-mechanical simulator. To describe the hot-working behaviour, the steels were compressed to the various amount of...
Purpose: The purpose of this work is to present the influence of wettability improvement of sintered Al2O3particles by deposition of Ni-P coating. Design/methodology/approach: The material for investigations was manufactured by pressure infiltration method of ceramic porous preforms. The eutectic aluminium alloy EN AC - AlSi12 was use as a matrix while as reinforcement were used ceramic preforms manufactured...
