摘要:
通过爆炸焊接技术制备60/65 mm×3500 mm×15 500 mm的超大尺寸钛钢复合板，并进行超声无损检测、相控阵波形形貌、界面组织形貌、EDS成分分析及力学性能试验。结果表明：炸药参数应控制在爆速2200~2450 m/s、堆积密度0.76~0.80 g/cm3、猛度8.1~11.5 mm范围内，制备出的复合板各项力学性能满足NB/T 47002.3—2019标准的技术指标。界面形貌为典型波纹状结合，界面清晰均匀，在波形漩涡区存在少量的熔化，波幅和波长的比值在0.20~0.26之间。本研究采用“低能量”和“微梯度”的设计思想，即“最小作用量原理”及“气固二相流”，既解决爆轰能量不足、排气难度大引起的界面结合强度不高、弯曲测试分层，又避免能量过高引起的复合板界面“冲刷条”、边部开裂现象。揭示了大规格钛钢复合板的界面特点，为其制备提供了工艺实践参考，为后续优化复合板爆炸焊接工艺提供理论指导。
Abstract:
Titanium-steel composite plates with ultra large size 6.0/65 mm×3500 mm×15500 mm were fabricated by explosive welding technology, and ultrasonic non-destructive testing, phased array waveform morphology and interface microstructure morphology characterizations, EDS elements analysis and mechanical property testing were carried out. The results showed that the explosive parameters should be controlled within the range of explosion velocity 2200~2450 m/s, packing density 0.76~0.80 g/cm3, and brisance 81~11.5 mm. The mechanical properties of the prepared composite plates meet the technical index of standard NB/T 47002.3—2019. The interface morphology is a typical wavy combination, the interface is clear and uniform, there is a small amount of melting in the vortex area of the waveform. The ratio of waveform amplitude to waveform wavelength is between 0.20 and 0.26. This study adopts the process design concept of low energy and micro-gradient, namely “the principle of minimum action” and “gas-solid two-phase flow”. It not only solves the problems of insufficient detonation energy and difficult exhaust, which cause low interface bonding strength and delamination during bending tests, but also avoids the phenomenon of “erosion strips” and edge cracking at the composite plate interface caused by excessive energy. In this study, the interface characteristics of large-sized titaniumsteel composite plates are revealed, providing a technological reference for the preparation of large-sized titanium-steel composite plate and theoretical guidance for the subsequent optimization of the explosive welding process for composite plates.
