在1987年8月,我国首次在空间微重力条件下的材料加工试验中,航天工业部三院八三五八所成功地进行了一次MCT晶体生长试验。这次试验是与航天部五院五一○所合作进行的。由五一○所提供晶体生长设备,航天工业部三院八三五八所提供实验方案、实验样品和结果分析。根据五一○所提供的温场条件和降温速度较快的特点,考虑到MCT晶体生长的特殊性,航天工业部三院八三五八所确定了在空间微重力条件下将MCT多晶试样重熔、再铸锭,然
In August 1987, for the first time in our country, the experiment of material processing under the conditions of space microgravity was successfully conducted at the 8358th institute of the Aerospace Industry Ministry. This experiment was conducted in cooperation with the May Day of May 5 of the Ministry of Space. Provided by the 51st crystal growth equipment, aerospace industry Hospitals 8,358 provide experimental programs, experimental samples and results analysis. According to the temperature field conditions provided in May 2010 and the characteristics of rapid cooling rate, taking into account the particularity of the crystal growth of MCT, Institute of Aeronautics and Astronautics 815880 determined under the conditions of space MCT polycrystalline test Like remelting, and then ingot, of course
