The demand for Ni-based brazing filler metals with melting temperatures below 1000 °C and good corrosion resistance is increasing because lower temperatures allow for the use of continuous belt furnaces rather than batch vacuum furnaces and are compatible with base metals that cannot withstand temperatures over 1000 °C. Based on this background and to explore the possibility of manufacturing Ni-Cr-P-Si amorphous brazing foils, rapid solidification technology was used to investigate the effects of chromium, phosphorus, and silicon as alloying elements on the melting characteristics, amorphous forming ability and ductility of boron-free Ni-Cr-P-Si alloys. As a result, a novel boron-free Ni-25Cr-6P-3Si amorphous brazing foil with a melting temperature of 985 °C and good bending ductility was obtained. [ABSTRACT FROM AUTHOR] |
