Effect of service temperature on shear strength of TA2/Q235 explosive composite plate

doi:10.13251/j.issn.0254-6051.2020.04.026

Abstract

Abstract: The service process of TA2/Q235 explosive composite plate was simulated by heat treatment, and the influence of service conditions on the microstructure and shear properties of composite plate was revealed, the mechanism of shear damage was discussed, and the service temperature range of TA2/Q235 is defined. The results show that the higher the service temperature (>200 ℃) or the longer the service time is, the lower the shear strength. The main reasons for the decrease of bonding strength of TA2/Q235 explosive welded composite plate during high temperature service are the secondary recrystallizing of the interface bonding zone, and the further growth of intermetallic compounds. The TA2/Q235 explosive welded composite plate is suitable for long service below 500 ℃, and the service duration can't exceed 7 days at 500-600 ℃. If the service temperature of this material is increased to more than 500 ℃, the formation of intermetallic compounds must be strictly restricted.

Key words: TA2/Q235 composite plate, service temperature, shear strength, secondary recrystallization, intermetallic compound
