The preparation and mechanical properties of composites with 20 mol.% Al₂O₃ and 80% [3Yb–TZP] modified with strontium oxide are considered. It is shown that during heat treatment of the initial nanopowders the strontium hexaaluminate phase is formed in situ. Acorrelation was established between an increase in the concentration of the modifier and an increase in the volume fraction of the strontium hexaaluminate phase. It was revealed that modifier content above 3% brings about an increase in the porosity of the composites. It was determined that composites modified with 1 – 2 mol.% SrO have bending strength 850 MPa and crack resistance K_1c up to 11.3 MPa ∙ m^1/2.

考虑了用 20 mol.% Al ₂ O ₃和 80% [3Yb-TZP] 用氧化锶改性的复合材料的制备和机械性能。结果表明，在初始纳米粉末的热处理过程中，六铝酸锶相在原位形成。在改性剂浓度的增加和六铝酸锶相体积分数的增加之间建立了相关性。结果表明，改性剂含量高于 3% 会增加复合材料的孔隙率。经测定，用 1 – 2 mol.% SrO 改性的复合材料具有 850 MPa 的弯曲强度和高达 11.3 MPa ∙ m ^{1/2 的}抗裂性K _{1 c}。
