摘　　要：介绍了钛合金热成形和超塑成形用金属平台的材料选型和制备工艺研究情况,研究认为,选择高温合金替代目前国外采用的耐热钢材料优势非常明显;钢铁研究总院自主开发的热成形金属平台制备工艺比国外相关技术更加先进,制备的K403高温合金热成形平台服役表现良好,具备了生产钛合金热成形和超塑成形金属平台的能力。Material selection and fabrication of metal flat for titanium alloy hot forming and superplastic forming are introduced. Compared with heat resistant steels, superalloys are more suitable for fabricating the metal flat. The producing technology of the metal flat developed by Central Iron and Steel Research Institute (CISRI) has the advantage over the conventional technology. The homemade metal flat made of K403 superalloy works stably, which shows that CSRI has capability of producing the metal flat for titanium alloy hot forming and superplastic forming.
