采用原位原子力显微镜（AFM）和纳米光刻技术研究了TiC颗粒和TiB晶须增强Ti-6Al-4V合金基复合材料在拉伸加载过程中的纳米变形行为。利用原子力显微镜纳米光刻技术在抛光表面形成光栅图案，便于直接观察局部变形。对复合材料在不同载荷作用下的局部变形行为进行了原位观察。对不同加载阶段的纳米尺度变形和损伤演化进行了测量和分析。
The nanoscopic deformation behavior of a TiC particle and TiB whisker reinforced Ti–6Al–4V alloy matrix composite during tensile loading was investigated by in situ atomic force microscopy (AFM) observation coupled with nanolithography. The AFM nanolithography technique was used to create a grating pattern on the polished surface to facilitate direct observation of local deformation. In situ observation of the composite subjected to tension was conducted to identify local deformation behavior under various applied loads. Nanoscale deformation and damage evolution during various stages of loading were measured and analyzed.
