The current study investigates the uniaxial tensile deformation and damage mechanism in single-crystal Aluminum (Al) in the presence of soft and hard inclusions. Spherical shaped Magnesium (Mg) and Titanium (Ti) are added as inclusions within an Al single crystal. Alteration in mechanical properties has been noticed in the presence of inclusions. Softening has been observed in the presence of Mg; while hardening in the presence of Ti. Low Young modulus of Mg inclusion and lack of dislocation activity results in less deformation, higher stress concentration at the interface, and early void nucleation in Al+Mg system. While high Young modulus of Ti inclusion and substantial dislocation activity prevails the large deformation, lower stress concentration at the interface, and slow fracture in Al+Ti system. The study provides an understanding of the governing fracture mechanism influenced by the inclusion.

当前的研究研究了在存在软硬夹杂物的情况下单晶铝（Al）的单轴拉伸变形和损伤机理。球形镁（Mg）和钛（Ti）作为夹杂物添加到Al单晶中。在存在夹杂物的情况下，已经注意到机械性能的改变。在镁的存在下观察到软化。在钛的存在下硬化。Mg夹杂物的低杨氏模量和缺乏位错活性导致Al + Mg系统中较少的形变，较高的界面应力集中以及较早的空核形核。Ti夹杂物的高杨氏模量和显着的位错活性占较大的形变，界面处的应力集中较低，而Al + Ti系统的断裂较慢。
