| 英文摘要 | The effects of gravity and crystal orientation on the dissolution of gasb into insb melt and the recrystallization of ingasb were investigated under microgravity condition using a chinese recoverable satellite and under normal gravity condition on earth. to investigate the effect of gravity on the solid/liquid interface and compositional profiles. a numerical simulation was carried out. the insb crystal melted at 525 degrees c and then a part of gasb dissolved into the insb melt during heating to 706 degrees c and this process led to the formation of ingasb solution. ingasb solidified during the cooling process. the experimental and calculation results clearly show that the shape of the solid/liquid interface and compositional profiles in the solution were significantly affected by gravity. under microgravity, as the ga compositional profiles were uniform in the radial direction. the interfaces were almost parallel. on the contrary, for normal gravity condition, as large amounts of ga moved up in the upper region due to buoyancy, the dissolved zone broadened towards gravitational direction. also. during the cooling process, needle crystals of ingasb started appearing and the value of x of inxga1-xsb crystals increased with the decrease of temperature. the gasb with the (111)b plane dissolved into the insb melt much more than that of the (111)a plane.
