Microstructure and microhardness of a novel TiZrAlV alloy by laser gas nitriding at different laser powers
Abstract The Ti–20Zr–6.5Al–4V (T20Z, wt%) alloy surface was treated by the process of laser surface nitriding. The evolution of microstructures and microhardness has been investigated by changing the
The studies of directional solidified RE-CO magnets
A new kind of rare-earth-cobalt material, Sm 20-24 wt.%/Ce 5-10 wt.%/Fe 8-15 wt.%/Cu 6-15 wt.%/Zr 1-3 wt.%/Co, has been made by directional solidification technology with liquid metal cooling
