1·In cooling process, when the temperature changed rapidly, the small particle would be obtained resembling the quencher.
降温很快时，与金属冶炼中的淬火相似，快速降温生成小晶粒。
2·Sample A whose surface has layer structure via oxidize-deoxidize treatment and sample B which is decarbonization are put into resistance furnace for carbonization and quencher under hydrogen.
将其中试样A通过氧化-还原处理，表面具有层状结构，与另一脱碳试样B一起放入改造后的电阻炉内在通氢气的气氛中进行渗碳淬火。
