1990年5月10日～13日,冶金工业部和航空航天工业部在丹东市联合召开GH696合金研究与应用鉴定会。会议代表近30人。冶金部北京钢研总院高温合金研究室主任杨锦炎代表冶金部主持了会议。 GH696合金是铁基时效硬化型高温合金,是为我国自行设计的WP15航空发动机研制的、1980年,上钢五厂,抚顺钢厂、上海钢研所、北京钢研总院、沈阳410厂、航空部621所等联合承担了该合金的研制和应用任务。会上,上海钢研所代表介绍了《GH696铁基时效硬化型高温合金的研究》,《C、Ti、Mo微量元素对GH696合金组织与性能的影响》,《GH696 May 10, 1990 ~ 13, the Ministry of Metallurgical Industry and Aerospace Industry Department jointly held in Dandong GH696 alloy research and appraisal. Nearly 30 delegates attended the meeting. Ministry of Metallurgy Beijing Institute of Iron and Steel Research Institute superalloy Yang Yan on behalf of the Ministry of Metallurgy presided over the meeting. GH696 alloy is an iron-based age-hardening superalloy developed for China’s own WP15 aircraft engine. In 1980, the No. 5 Steel Plant, the Fushun Steel Plant, the Shanghai Steel Research Institute, the Beijing Steel Research Institute, the No. 410 Plant in Shenyang, Ministry of Aeronautics 621 jointly assumed the development and application of the alloy task. At the meeting, Shanghai Steel Research Institute introduced “GH696 iron-based age-hardening superalloy”, “C, Ti, Mo trace elements on the microstructure and properties of GH696”, "GH696
