Streszczenie

The paper presents the results of study of the influence of the volume fraction of TiN phase on the microstructure and mechanical properties of the ceramic particulate composite Si3N4-TiN. Samples of the Si3N-TiN composite containing 5, 10, 15 or 20 vol. % of TiN phase were obtained by sintering mixtures of TiN and Si3N4 powders and sintering additives (6 wt % aluminium oxide and 4 wt % of yttrium oxide). Two types of TiN powder differing in the degree of fragmentation were used. Sintering was conducted at a pressure of 25 MPa at 1750°C for 1 hour. The resulting materials were subjected to quantitative analysis of the microstructure in order to determine the effect of TiN volume fraction and kind of TiN powder used on the microstructure of composites. Binary images showing the Si3N4 grains or TiN particles were obtained by the processing and binarization of SEM gray images of composite microstructure using the Aphelion computer software. The values of selected stereological parameters determining the size, shape and uniformity of distribution of the TiN particles and the size and shape of the matrix grains were determined. The study of the composite microstructure showed that for both types of TiN powders the increase of TiN volume fraction does not cause significant changes in size and shape of the Si3N4 grains. The increase in volume fraction of TiN phase produces the increase in the average TiN particle size in the composite, but cause only a slight change in their shape. Titanium nitride particles in the composite were smaller and somewhat more isometric and more uniformly distributed in the matrix when fine TiN powder was used. Measurements of flexural strength σf and fracture toughness KIc of all materials samples were conducted to determine the effect of composite microstructure changes on mechanical properties. The flexural strength and fracture toughness of the composites increase with the volume fraction of TiN phase. Composites with finer TiN particles are preferable from the point of view of better flexural strength, but higher values of fracture toughness are obtained for composites with coarser TiN particles.

Abstract

W celu doskonalenia właściwości mechanicznych ceramiki z azotku krzemu tworzy się kompozyty ziarniste o osnowie z Si3N4, a jednym z takich materiałów jest kompozyt Si3N4-TiN. W kompozytach ziarnistych istotnymi zmiennymi mikrostrukturalnymi są m.in. udział objętościowy fazy rozproszonej, wielkość i kształt cząstek tej fazy oraz sposób ich rozmieszczenia w osnowie kompozytu. Celem pracy jest zbadanie wpływu udziału objętościowego fazy TiN oraz stopnia rozdrobnienia proszku TiN użytego do wytworzenia kompozytu Si3N4-TiN na jego mikrostrukturę oraz twardość, wytrzymałość na zginanie i odporność na kruche pękanie.
