Shape Accommodation of grains during liquid phase sintering has been investigated. Specimens of 85Mo-15Ni (by weight %) and substrates of 98Mo - 2Ni are pre-sintered at 1450℃ separately. After presintering, the specimen and the substrate are resintered together in various cycles at 1450℃. The shape change of the grains during sintering cycles can be determined by etch boundaries revealed within grains after a strong etching in Murakami solution. During resintering, a part of the liquid in the specimens has been absorbed by the substrates, and the grains in the specimens are shape accommodated through subsequent grain growth. The driving force for the grain shape accommodation in the specimens is explained to be the sphering force of the grains in the substrates, which had been strongly shape-accommodated.
