高性能钛/钢爆炸复合板的制备及性能分析
Preparation and Analysis of High-Performance Titanium/Steel Composite Plate
摘要: 采用爆炸复合法制备了钛(TA1)/钢(Q345R)层状复合材料，并在540℃下进行消应力热处理。通过金相显微镜、显微硬度仪、万能试验机等对TA1/Q345R复合材料的界面形貌、力学性能进行了分析。实验结果表明：4号试样界面的硬脆相最少，波幅比为0.27，剪切强度高达267.5 MPa，远高于《NB/T 47002.3-2019》标准的要求，可满足对剪切强度要求较高环境的应用。
Abstract:
TA1/Q345R cladding metal plate was prepared by explosive cladding method, and the heat treatment for stress elimination was carried out at 540℃. The interface morphology and mechanical properties of TA1/Q345R plates were analyzed by metallographic microscope, micro-hardness testing machine and universal mechanical testing machine. The results illustrate that the hard and brittle particles of sample No.4 is in the least amount, and the ratio of crest and width is 0.27, and the maximum of shear strength is 267.5 MPa, higher than standards of NB/T47002.3-2019, which can meet the requirements of high shear of the operating conditions.
