Material Specification for ; [Y-Ni-B-C] Process: Melt Processed
Notes: "Samples of nominal composition Y1+δNi4-xB1+x (δ ≤0.05) were prepared by high-frequency induction melting, subsequently annealed in argon at 800 °C for 50 h and quenched in water. Both arc and high-frequency melting were used for the preparation of the YNi2B2C specimens. The annealing was carried out at 1050 °C for 24-36 h. Losses of C were compensated by an extra amount of 10% added beforehand."

Measurement Method: X-ray diffraction
"Lattice parameters were determined at room temperature with CuKα1 radiation in a Gunier-Huber camera employing an internal standard of 99.9999% pure Ge. X-ray diffraction intensity data for structure refinement were obtained from a flat sample surface on a Siemens D5000 powder diffractometer with CuKα radiation. Rietveld full matrix full profile refinements were performed using the program DBW."
