Abstract

The invention relates to a laminated titanium-magnesium composition plate and a preparation method thereof. The composite plate is characterized in that the total thickness is 6 mm, a cladding is TA1 and has a thickness of 1.5 mm, a base layer is AZ31B and has a thickness of 4.5 mm, and the thickness ratio of the TA1 layer and the AZ31B layer is 1:3. The invention also relates to a preparation method of the laminated titanium-magnesium composition plate. The preparation method mainly comprises the following five steps: first, selection of the sizes of raw materials; second, polishing of surfaces to be composited; third, explosive welding; fourth, annealing; and fifth, leveling. The adoption of the laminated composite plate preparation method can prepare a TA1 / AZ31B composite plate which has good boundary jointing and is 6 mm thick.

Description

technical field [0001] The invention relates to a layered titanium-magnesium composite board and a preparation method thereof. Background technique [0002] Titanium and titanium alloys have many excellent properties, such as low density, high specific strength, corrosion resistance, high temperature impact resistance, etc., but the price is high; magnesium and magnesium alloys are the metals with the smallest density among structural materials so far, and the price is low. But the corrosion resistance and high temperature resistance are poor. [0003] How to combine the advantages of the two to prepare a layered titanium-magnesium composite board has become an urgent problem in this technical field. [0004] Explosive welding is a process technology for manufacturing dissimilar metal layered composite panels, which has been widely used in double or multilayer composite panels such as titanium / steel, steel / stainless steel, titanium / steel / stainless steel, copper / aluminum, c...
