急冷淬火获得的马氏体记忆效应略低且恢复温度较高。
Martensite obtained by rapid quenching has a slightly lower shape memory effect and a higher recovery temperature.
采用真空控时急冷技术对H13钢热作模具进行淬火，可使之得到细小的马氏体组织，从而显著提高热作模具的冲击韧度。
Hot working dies of H13 steel vacuum quenched by the use of the time-controlled sudden cooling technology will obtain fine martensite.
