钛和钛合金材料的优点是比强度高,耐热性、耐蚀性好,所以在飞机结构中得到了普遍的应用。它的缺点是塑性差、塑性变形范围小、回弹大、缺口敏感性高,因此用常规的方法在室温下只能制造形状简单、变形量小的零件,多数零件需在热状态下成形和校形。从生产实践中体会到,使钛板在温度、时间、压力三者的联合作用下成形和校形,将能获得贴模 Titanium and titanium alloys have the advantages of high strength, heat resistance, corrosion resistance, so the aircraft structure has been widely used. It has the disadvantage of poor plasticity, small plastic deformation range, large springback and high notch sensitivity. Therefore, conventional methods can only manufacture parts with simple shapes and small deformations at room temperature. Most parts need to be formed in a hot state School shape. Experience from the production of experience, the titanium plate in the temperature, time, pressure under the combined action of the three forming and calibration, will be able to get stickers
