Interface Characteristic of Explosive-Welded and Hot-Rolled TA1/X65 Bimetallic Plate

Abstract

TA1/X65 bimetallic plate has a bright future of application by combining the excellent corrosion resistance of TA1 and the high strength of inexpensive X65 steel, while manufacturing large size TA1/X65 bimetallic plate is still a challenging task. Multi-pass hot-rolling is the most common way to achieve a large size bimetallic plate. In this work, interface characteristic of explosive-welded and multi-pass hot-rolled TA1/X65 bimetallic plate is experimentally studied. The microstructure, composition and microhardness distribution across the TA1/X65 interface are investigated by optical metallographic observation, scanning electron microscope (SEM) observation, energy dispersive spectrometer (EDS) analysis, and Vickers hardness test. Shear tests and stratified tensile tests are conducted with emphasis on impacts of the angle between loading direction and detonation wave propagation direction on interface strength. A straight TA1/X65 interface with periodic morphology of residual peninsula could be observed on the cross section parallel to detonation wave propagation direction, while in most cases there is no residual peninsula morphology on the straight TA1/X65 interface when the cross section is perpendicular to detonation wave propagation direction. TA1/X65 interface of explosive-welded and multi-pass hot-rolled bimetallic plate presents higher bearing capacity for the load perpendicular to detonation wave propagation direction than that for the load parallel to detonation wave propagation direction. The results of this paper have a certain guiding significance for the fabrication of pipes and containers made of explosive-welded and hot-rolled TA1/X65 bimetallic plate.

High-Velocity Impact Welding Process: A Review

“…As its name suggests, explosives detonation is implemented to provide the impact force for the flyer. It was reported that more than 200 material combinations have been successfully welded by EXW [22], for example, Fe/Ti [23][24][25], Zr/Fe [26], Al/Ti [27], Ti/Ni [28], and Al/Fe [29,30]. For plate welding, two generally used experimental setups are the inclined mode and parallel mode, as shown in Figure 2.…”

The Effect of Interface Morphology on the Electro-Mechanical Properties of Ti/Cu Clad Composites Produced by Explosive Welding

“…LAYERED composites with built-in functionalities are attractive materials for many industrial applications because they offer an optimum balance between manufacturing and service costs, and the durability to perform under their conditions of use. For example, bi-and multi-layer materials composed of reactive metals are used in power, [1] chemical, [2,3] and shipbuilding [4][5][6][7] industries, where corrosive wear of equipment is a significant problem. Many material issues related to the use of hydrogen as a fuel can also be solved by the use of layer composites based on reactive metals.…”

The Influence of Heat Treatment Parameters on the Cracks Growth under Cyclic Bending in St-Ti Clad Obtained by Explosive Welding

“…The research centers involved in analyzing these mechanisms worldwide are: Clad Metal Products USA, the Russian Academy of Science, University in Zagreb Croatia, Sakarya University in Turkey, the University of Tehran in Iran. Very intensive research in this area is in progress in China [3,4]. In Poland, it is studied in centers such as: the Military University of Technology, the Polish Academy of Sciences, UTP University of Science and Technology in Bydgoszcz and Opole University of Technology [5,6].…”

“…The purpose of this paper was to test the structural changes and crack growth after cyclic bending of the steel-titanium clad subjected to heat treatment with various temperature and times of annealing. Investigation of the propagation of fatigue cracks and fatigue life obtained by the method of explosive welding for steel-titanium bimetals is not a common area of focus [19], as research has mainly focused on the bonding process and its parameters [2,3]. However, these studies are particularly relevant due to their high industrial importance.…”
