研究了在两种稳定y2o3的ZrO2陶瓷中，随着压痕载荷的增加，维氏压痕诱导轨迹的发展。这种裂缝在低荷载下形成放射状或帕姆奎斯特裂缝，在中等荷载下呈“肾”状，在高荷载下最终形成中位数（半便士）裂缝。压痕正下方的塑性区未开裂；压痕引起的塑性很大一部分是由马氏体相变引起的。
The development of Vickers indent-induced tracks with increasing indent load has been studied in two Y2O3-stabilizel ZrO2 ceramics. Such cracks form as radial or Palmqvist cracks at low loads, assume “kidney” shapes at intermediate loads, and finally form median (half-penny) cracks at high loads. The plastic zone directly beneath the indent is uncracked; a significant portion of the plasticity induced by indentation occurs by martensitic transformation.
