摘要
探讨了爆炸焊接结合区波形形成的机理 ,指出了这种波形是在爆炸载荷下在相互撞击的金属界面上所发生的一种不可逆的和周期性波动分布的塑性变形 .它的形成必有外因和内因 ,外因是在金属中波动传播的爆炸载荷 ,内因是待焊接的金属材料 .在爆炸载荷下在金属材料界面上所发生的冲击碰撞是波形形成的不可缺少的过程和手段 ,为此提出了一个与此波形形成的流体力学机理相对立的金属物理学机理 .本文从金属物理学和哲学的基本原理出发分析了此波形形成的原因 ,并用大量实验事实论证了此波形形成的外因的存在和内因的影响 .
The wave formation mechanism in the bonding zone of explosive welding is discussed.It is pointed out that the wave is an irreversible plastic deformation of periodically fluctuateddistribution taking place on the metal surface by collision with each other under the explosion load.The formation of wave must have its internal cause and external cause;the external cause is the explosion load fluctuatedly spread in the metal and the internal cause is the metal materials to be welded.The impulsing collision on the interface of the metal materials under the explosion load is the indispensable course and means for wave formation.For this reason,the metal physics mechanism is proposed as a rival equal to the mechanism of fluid mechanics.The cause of the wave formation is analyzed with the metal physics mechanism and the fundamental principle of philosophy,and a large amount of facts are cited to demonstrate and prove the influence of internal cause and external cause on the wave formation.
