    摘要:

    研究了1060Al/TA2/CCSB爆炸復(fù)合板結(jié)合界面在不同退火溫度下的顯微組織、力學(xué)性能。結(jié)果表明,復(fù)合板在其界面處呈現(xiàn)連續(xù)均勻分布的波狀結(jié)合,界面處存在漩渦、熔化塊、表面微裂紋和絕熱剪切帶等缺陷。對(duì)復(fù)合板進(jìn)行拉脫測(cè)試和剪切測(cè)試,拉脫斷裂發(fā)生在1060Al/TA2界面,1060Al/TA2界面的剪切強(qiáng)度低于TA2/CCSB界面。復(fù)合板波狀界面的存在,阻礙了拉伸過程中的頸縮過程,使復(fù)合板塑性提高。隨著退火溫度升高到400℃,結(jié)合界面發(fā)生回復(fù),消除了加工硬化效應(yīng),使得界面硬度降低;ASB消失并轉(zhuǎn)變?yōu)榈容Sα晶粒,缺陷減少;界面處的熔化塊發(fā)生溶解,使復(fù)合板結(jié)合界面組織結(jié)構(gòu)更加均勻,獲得良好的綜合性能。

    Abstract:

    The microstructure and mechanical properties of 1060Al/TA2/CCSB explosive composite plate binding interface at different annealing temperatures were studied. The results show that the composite plate exhibits a continuous and uniform distribution of waves at its binding interface, there are swirls, melting blocks, surface microcracks and ability shear strips other defects. Take a test, cutting test, and microhardness testing on the composite plate, pulling breakage occurs at the 1060Al/TA2 interface, the shear strength and the microhardness of the 1060Al/TA2 interface are lower than the TA2/CCSB interface, and the binding interface is severe Plastic deformation, resulting in processing hardening and grain refinement of the composite plate interface, and the hardness value at the interface is highest and along the boundary to the matrix gradient distribution. The existence of a composite palette hinders the necklace process during the stretching process, and the composite plate is improved. As the annealing temperature rose to 400℃, the combined interface responded, the processing hardening effect was eliminated, so that the interface hardness was lowered; the ASB disappeared and converted into an equal shaft alpha grain, defect decreased; the melting block at the interface was dissolved, so that the composite The binding interface of microstructure is more uniform and good comprehensive performance is obtained.
