Purpose: The aim of this work was to investigate the changes taking place in the structure and properties of silver-mishmetal alloys caused by severe plastic deformation compared to the Ag+(7.5 wt %)Cu alloy and pure Ag materials. Design/methodology/approach: Tests were made with samples obtained by melting and casting in an induction furnace. Further plastic working included KOBO® extrusion process...
Purpose: The objective of this work was to investigate the changes taking place in the structure and properties of Ag-La (0.5%) and Ag-mishmetal (1 and 4%) alloys caused by severe plastic deformation compared to the Ag+(7.5 wt %)Cu alloy and pure Ag materials. Design/methodology/approach: Tests were made with the samples obtained casting and further plastic working included KOBO® extrusion process...
Purpose: The objective of the work was to investigate changes in structure and properties of Cu-WC microcomposites which take place in the process of controlled hot deformation of materials of nanometric initial structure. Design/methodology/approach: Tests were made with the Cu-WC micro-composites containing up to 2% of a hardening phase. These were obtained by powder metallurgy techniques and further...
