双金属复合管由两种不同的金属材料构成，与单一金属管相比，复合管充分利用基管和覆管的最佳性能，可被广泛应用于石油、化工、核工业、医疗、食品等领域。目前研究多集中在双金属直管成形中。本文提出一种采用液压成形工艺套接成形双金属复合异形管的方法，重点考虑加载路径、加载方式、材料的变形程度、摩擦力对变形的影响等问题。通过数值模拟方法，获得双金属异形管成形中的关键技术参数，初步探讨了多金属异形管的成形问题。

Bimetal composited tube is constituted by two different metals.Compared with single metal tube,composited tube can make the best of optimum performance of based tube and clad tube,and could be widely applied in the petrochemical,nuke,med-ical appliance and food fields.In the present research,straight bimetal tubes are taken as the objectives and studied deeply.A new hydroform process is introduced,which can be used to form bimetal composited special tubes.Loading path,loading meth-od,deformation of material,effect of frictional force,etc.are studied fully using numerical simulation and the key technique and specialty of this technology are gained.The multi-metal special tube is discussed preliminarily.
