- 論文の詳細を見る
Symmetrically graded laminates of the Al_2O_3/TiC/Ni/TiC/Al_2O_3 were fabricated by SHS/HIP process. Compressive residual stresses as high as 100〜300MPa were introduced into the outer Al_2O_3 layers by utilizing the thermal expansion mismatch between the outer and inner layers. The effect of the surface compressive residual stress on the strength and toughness of Al_2O_3 was evaluated by three point bending tests and the Vicker's indentation method. The results showed that the surface compressive stress can effectively improve the strength and toughness of the ceramic laminates.
