In situ neutron diffraction has been used to study the tensile deformation behaviors of a ZrTi-based bulk metallic glass matrix composites (BMGMC) at room temperature. The crystalline phase yielded prior to the amorphous phase during the tensile loading, and the glassy matrix bore more stress partition during the plastic deformation stage. A redistribution of the applied stress in dendrites occurred in the grains with an orientation of (110) and (200) during the plastic deformation. This work provides new insights into the tensile deformation mechanism of the BMGMCs at the microscopic level.

原位中子衍射大块金属玻璃基复合材料的拉伸变形机理

原位中子衍射已用于研究ZrTi基块状金属玻璃基复合材料（BMGMC）在室温下的拉伸变形行为。在拉伸载荷过程中，结晶相先于非晶相而屈服，而玻璃状基体在塑性变形阶段承受了更大的应力分配。在塑性变形过程中，晶粒以（110）和（200）取向在晶粒中发生了应力的重新分布。这项工作在微观水平上为BMGMC的拉伸变形机制提供了新的见解。
