GH901合金真空熔炼铸锭中硼的宏观偏析，是由硼在GH901合金中的三大特点决定的。
Macrosegregation of boron in vacuum melting pouring ingot of GH901 alloy is determined by3 characteristics of boron in the GH901 alloy .

因而，真空感应熔炼铸锭中硼的宏观偏析程度主要取决于浇注温度、全熔后的保温温度和保温时间。
So , degree of macrosegregation of boron in VIM ingot depends on mainly pouring temperature , holding temperature and holding time after full melting .

而真空电弧重熔铸锭中硼的宏观偏析主要与熔池的大小和深度有关，因而主要取决于稳定熔炼电流的大小。
Degree of macrosegregation of boron in VAR ingot is controlled mainly by melting bath width and depth , so it depends mainly on how much stable melting current is .
