Interfacial evolution and mechanical behavior of explosively welded titanium/steel joint under subsequent heat treatment process

Explosive welding (EXW) has advantages in joining metallurgically incompatible metals due to its high quality and simple process. Successful titanium/steel clad plates fabricated by explosive have been extensively reported recent years. However, no research on the fabrication of explosively welded TA2/15CrNi3MoV effect subsequent heat treatment processes plates. This study aims clarify microstructure evolution mechanical behavior during The were heat-treated temperature range 700–1000 °C for 30 min. results elucidated that process accelerated interdiffusion constituent elements (e.g., Fe, Ti, C) at interface, which formed FeTi, Fe2Ti, TiC. For samples 700 °C, a continuous TiC layer was generated hampered formation FeTi Fe2Ti. 800 broken up, resulted significant increase Fe-Ti 1.21 μm. dramatically dropped tensile strength 329.2 MPa. 900–1000 thickness brittle increased caused rapid drop strength.
