- 摘要:
17-4PH沉淀硬化型马氏体不锈钢具有强度高、抗衰减性能好，抗腐蚀疲劳及抗水滴性能强等特点，被广泛应用于航空航天、军工、海上平台等领域。综述了热处理对17-4PH高强钢组织与性能及强韧化机制等方面的研究现状，包括强度、硬度、腐蚀疲劳、冲击韧度、滞后性等；提出了17-4PH高强钢热处理中存在的问题，并从提高生产效率、扩大应用范围的角度展望了未来的发展方向。
17-4PH precipitation-hardened martensitic stainless steel is widely used in aerospace, military, offshore platforms and other fields with high strength, good attenuation resistance, corrosion fatigue resistance and water drop resistance. The research status of heat treatment on the microstructure, properties and toughening mechanism of 17-4PH high strength steel were reviewed, including strength, hardness, corrosion fatigue, impact toughness and hysteresis. The problems existing in the heat treatment of 17-4PH high strength steel are put forward, and the development direction of the steel in the future is forecasted from the angle of improving production efficiency and expanding application scope.
