钛/钢爆炸焊接界面波形及缺陷组织的形成机理
|
摘要
为探讨钛/钢爆炸焊接界面波形的形成过程和缺陷组织的形成机理,以台阶型基板爆炸焊接装置为例,选取厚度为2 mm的钛板和钢板以5、7、9、11 mm为间距进行爆炸焊接实验,并采用Autodyn动力学软件进行仿真模拟。将采用的光滑粒子动力学(SPH)数值模拟结果与实验结果作对比,观察焊接界面电镜扫描(SEM)图片中的旋涡状结晶熔池和碰撞粒子的速度矢量图。研究表明:光滑粒子动力学数值模拟方法适用于模拟爆炸焊接等金属碰撞接触的大变形行为;爆炸焊接实验中出现的界面波形的形成原因可用碰撞局部金属流体的相互侵彻理论来解释;基板和复板碰撞处的金属涡流是焊接界面形成缺陷组织的主要原因。
In order to explore the formation mechanism of the waves of the Ti/Steel explosive welding section.The explosive welding of Ti/Steel test is carried out with stepped immobile plates.The thickness of titanium plate and steel plate is 2 mm and the spacing between titanium plate and steel plate used in explosive welding experiment is 5,7,9 and 11 mm,respectively.The model of Ti/Steel explosive welding was established in Autodyn.The smoothed particle hydrodynamics(SPH) numerical simulation results are compared with the experimental ones.The swirling crystal pool in the scanning electron microscope(SEM) picture of welding interface and velocity vector diagram of colliding particles are obtained and analyzed.Results indicate that the smoothed particle dynamics simulation method is suitable for simulating the large deformation behavior of metal collision during explosive welding.The reason for the formation of interfacial waves in explosive welding experiment can be explained by the penetration theory of local metal fluid.And the main reason for the defects can be attributed to the metal eddy current at the collision between fly and immobile plates.
