Abstract

The invention discloses a composite board prepared by accumulative roll bonding of aluminum plates and titanium plates and a preparation method of the composite board. The preparation method comprisesthe following steps: performing accumulative assembly on two layers of titanium plates and three layers of aluminum plates to obtain accumulated plates, fixedly bundling and uniformly preheating theaccumulated plates, performing accumulative assembling for three times, fixed bundling and rolling so as to obtain three-rolling plates, and finally performing heat treatment on the three-rolling plates, thereby obtaining the composite board. According to the preparation method disclosed by the invention, process requirements are simple, the preparation efficiency is high, the cost is low, and theprepared composite board is excellent in bonding interface and excellent in mechanical property.

Description

technical field

[0001] The invention belongs to the field of composite metal materials, and in particular relates to a composite sheet of aluminum sheet and titanium sheet cumulative rolling (ARB) and a preparation method thereof. Background technique

[0002] Aluminum has low density, good plasticity and excellent formability, and has good electrical and thermal conductivity, and the price is low; titanium has high strength, good rigidity, excellent impact resistance, and has good thermal strength and corrosion resistance. It still maintains stable mechanical properties under low temperature and ultra-low temperature conditions, and is widely used in aerospace and general industries, but its price is high.

[0003] Aluminum and titanium have unique application values ​​due to their respective characteristics. The preparation of aluminum-titanium-aluminum composite materials by cumulative rolling can not only have the formability and good plasticity of aluminum, but also ref...
