Conclusion: stretching, shearing, coloring and penetrating inspection and ultrasonic flaw detection are carried out according to the standard of ASTMB898 active and refractory metal composite plate;
the tantalum titanium steel composite board subjected to explosion compounding by adopting a direct explosion compounding mode has fine cracks around, a large-area non-lamination area appears on the surface of the flaw detection board, and the shearing strength is 128Mpa and 138Mpa. The tantalum titanium steel composite board subjected to explosive cladding in a secondary explosive cladding mode has excellent performance, and the non-bonding scope of the boundary is well controlled, so that the tantalum titanium steel composite board can meet the standard requirements.
The thickness of the middle bonding layer of the composite board shows the bonding condition of the composite board, and the thickness of the middle bonding layer is mainly the kinetic energy loss in the movement process of the composite board, chemical energy generated by explosive explosion is converted into the kinetic energy of the composite board, and the kinetic energy of the composite board is correspondingly reduced during explosion and compounding. In the comparative example, explosion compounding is directly carried out, chemical energy released by the explosive is converted into kinetic energy of the tantalum plate, and when the kinetic energy of the tantalum plate reaches the titanium plate and the steel plate, the kinetic energy of the composite plate is reduced more, so that the thickness of a bonding layer between the titanium plate and the steel plate is thinner and the situation that the thickness of a bonding layer of a region is uneven occurs. In the embodiment, the explosion compounding is carried out twice, so that the kinetic energy of the compound plate can be fully exerted when the explosion compounding is carried out each time, and the thickness of the middle bonding layer of the compound plate is obviously better than that of the bonding layer when the explosion compounding is directly carried out each time. Through ultrasonic flaw detection, the composite board of secondary explosion complex is except boundary non-laminating region and detonating point, and non-laminating region is less, and the large tracts of land non-laminating region appears in the compound face of direct explosion. In the shearing test, the samples are respectively taken from the parts with better ultrasonic flaw detection laminating areas, and the bonding strength of the secondary explosion composite is obviously superior to that of the direct explosion composite.
The binding rate and the shearing strength of the tantalum-titanium-steel explosion composite board meet the requirements of the standard of ASTMB898 active and refractory metal composite board, meet the development needs of industries such as domestic chemical industry and the like, reach the binding rate of more than 99 percent, and have the minimum shearing strength of more than or equal to 140mpa. The tantalum-titanium steel composite board produced by adopting the explosion compounding method has the corrosion resistance of tantalum and the strength and plasticity of a common steel plate as a structural member, so that the cost is greatly reduced, and the application field of the tantalum-titanium steel composite board material is continuously widened along with the continuous progress of the equipment manufacturing technology in China.
