采用热压烧结法制备了Fe/Mo-Sialon新型金属陶瓷基复合材料。研究了陶瓷的相组成和力学性能。结果表明，Fe/Mo-Sialon陶瓷的主要相为β-Sialon、Mo、FeMo和FeSi 2。随着FeMo 70合金添加量的增加，抗弯强度先增加后降低。随着FeMo 70合金添加量的增加，硬度逐渐降低。制备的Fe/Mo-Sialon陶瓷的抗弯强度为426.7MPa，维氏硬度（HV0.5）为19.3GPa添加FeMo 70的合金具有最佳的力学性能。
A novel metal–ceramic matrix composite of Fe/Mo–Sialon was prepared by hot-pressed sintering. The phase composition and mechanical properties of the ceramic were studied. The results showed that main phases in Fe/Mo–Sialon contained β-Sialon, Mo, FeMo and FeSi2. The flexural strength initially increased, and then decreased with increasing FeMo70 alloy addition. The hardness decreased gradually with increasing FeMo70 alloy addition. With a flexural strength of 426.7MPa and a Vickers hardness (HV0.5) of 19.3GPa, Fe/Mo–Sialon ceramic with 19.3wt.% FeMo70 added exhibited the best mechanical properties.
