Microhardness as a tool for the filament density and metal sheath analysis in MgB2/Fe/(Cu) wires

Abstract:

Vickers microhardness measurements have been carried out on MgB 2 composite wires deformed in iron sheaths. Because the local hardness of these composite materials can be simply measured, we can use these values as an indication of the density of the ceramic core. An array of microhardness measurements have been done for single- and multi-core MgB 2 wires subjected to variable deformation and heat treatment processes. The results show how the fabrication process can affect the core density, a...
