Explosively welded layered materials made of (a) an AA2519 aluminum alloy (AlCuMgMn + ZrSc), (b) titanium alloy Ti6Al4V and (c) an intermediate layer composed of a thin aluminum alloyed AA1050 layer are considered herein. This study presents test results connected to measurement science including microstructural observations of the material combined with the explosive method, and a basic analysis of the strength properties based on microhardness and tensile tests. Owing to the joint's special manufacturing conditions, the laminate was subjected to deformation measurements with the digital image correlation (DIC) method. The research was supplemented by the residual stress measurements with the sin2ψ X-ray method based on the diffraction-reflection analysis that was verified by the bore trepanation method.
(a) AA2519铝合金(AlCuMgMn + ZrSc)、(b) 钛合金Ti6Al4V以及(c) 由薄铝合金化AA1050层组成的中间层。本研究展示了与测量科学相关的测试结果,包括结合爆炸方法对材料进行微观结构观察,以及基于显微硬度和拉伸试验对强度性能进行的基础分析。由于接头的特殊制造条件,采用数字图像相关(DIC)方法对层压板进行了变形测量。基于衍射反射分析的sin2ψ X射线法进行了残余应力测量,并用钻孔套钻法进行了验证,以此对研究进行补充。
