采用爆炸焊接方法对TA2与2 A12金属组合进行爆炸复合，并对获得的钛/铝爆炸复合板进行微观组织结构分析及力学性能测试。金相组织观察显示，复合板的结合界面以波状方式结合，在结合界面处产生了强烈的塑性变形。对复合板结合界面区进行XRD测试分析，未发现有金属间化合物析出，保证了结合界面具有较高的结合强度。力学性能测试结果表明，随着与结合界面之间的距离增大，其显微硬度逐渐降低，整体上复合板的力学性能良好，其拉伸强度和剪切强度等能够满足工业生产对其力学性能的要求。
採用爆炸銲接方法對TA2與2 A12金屬組閤進行爆炸複閤，併對穫得的鈦/鋁爆炸複閤闆進行微觀組織結構分析及力學性能測試。金相組織觀察顯示，複閤闆的結閤界麵以波狀方式結閤，在結閤界麵處產生瞭彊烈的塑性變形。對複閤闆結閤界麵區進行XRD測試分析，未髮現有金屬間化閤物析齣，保證瞭結閤界麵具有較高的結閤彊度。力學性能測試結果錶明，隨著與結閤界麵之間的距離增大，其顯微硬度逐漸降低，整體上複閤闆的力學性能良好，其拉伸彊度和剪切彊度等能夠滿足工業生產對其力學性能的要求。

The metal combination between TA2 and 2A12 is bonded together by using explosive welding . The microstructure of titanium/aluminium composite plate is investigated and the mechanical properties of composite plate are tested .The metallographic observation shows that the bonding interface of composite plate presents the pattern of wave shape ,and the violent plastic deformation is generated in the interface . The result of XRD analysis indicates that no intermetallic compounds precipitate in the interface region ,as a result ,the bonding strength of interface is relatively high .The results of mechanical properties tests show that the microhardness of composite plate gradually decreases with the distance far from interface .On the whole,the mechanical property of composite plate is better ,and their tensile strength and shear strength can meet the requirements of mechanical properties in industry production .
