Das Dreistoffsystem Nickel—Chrom—Bor

摘要

The ternary system Ni−Cr−B was established at 1000°C by X-ray diffraction and metallographic examinations. Binary chromium resp. nickel borides and two ternary borides Cr3NiB6and Cr2Ni3B6were confirmed. Differential thermoanalysis of binary Ni−B-alloys showed the possibility of a metastable solidification according the partial system Ni−Ni2B up to 19 at B. The melting temperatures of ternary alloys were est
