| controlled freezing; directional freezing (【技】应用特设装置，使熔体沿固定方向顺序凝固的过程。其条件是要保证热流只向着凝固界面推移的逆方向传输。通常采用的装置其主要部分由一个加热炉或保温炉和一个盛熔体的坩埚组成。利用定向凝固可以制造出单晶体、双晶体或具有织构的多晶体，对于易产生偏析的选分凝固合金，可以获得无成分偏析的铸件。); directional solidification (【技】应用特设装置，使熔体沿固定方向顺序凝固的过程。其条件是要保证热流只向着凝固界面推移的逆方向传输。通常采用的装置其主要部分由一个加热炉或保温炉和一个盛熔体的坩埚组成。利用定向凝固可以制造出单晶体、双晶体或具有织构的多晶体，对于易产生偏析的选分凝固合金，可以获得无成分偏析的铸件。); oriented solidification | |||
