The structure nonuniformity a VT23 titanium alloy after shock and vibration loading is established to lead to larger plasticity of the material and changes in fracture mechanisms. Localization of deformation processes influences the sizes and quantitative distribution of tear dimples on the fracture surface. The approach was advanced to detect tear dimples on the fracture surface of the alloy, in particular after shock and vibration loading. The fractographic inspection was used to compute the dimple parameters, among them area, number, equivalent diameter, and visual depth. The above parameters for the conglomerates of detected dimples became the basis for statistical analysis and establishment of additional fracture mechanisms of the alloy at the microlevel. It provides the grounds the grounds for preliminary comparative evaluation of the cond of titanium alloys, modified by shock and vibration loading, using fractographic examination data.

冲击和振动载荷对VT23钛合金断裂机理的影响

VT23钛合金在冲击和振动加载后的结构不均匀性被确定为导致材料的更大可塑性和断裂机理的改变。变形过程的局限性会影响裂缝表面上裂缝的尺寸和定量分布。改进了该方法以检测合金断裂表面上的撕裂凹痕，特别是在冲击和振动加载之后。形貌检查用于计算酒窝参数，其中包括面积，数量，等效直径和视觉深度。用于检测到的凹痕的团块的上述参数成为统计分析和建立合金微观水平上附加断裂机理的基础。
