Microstructural evolution of WC-Co materials with different compositions and WC grain sizes is discussed from SEM observations and quantitative image analyses of intercept length distributions in the WC phase. Effect of the C/W ratio in the binder ph

The liquid-phase sintering (LPS) of cemented carbides prepared from submicronic powders induces a micro-structural evolution generally ascribed to normal and abnormal grain growth. Such phenomena can be prevented by small additions of inhibitors (Cr,

A model was developed to describe the motion of particles which are connected by liquid bridges. The model takes into account capillary force, particles inertia, viscous drag of liquid, and elastic collision. Below a critical thickness of the liquid

The alloys with composition around Sm11.5Co58.4Fe22.5Cu5.3Zr2.4 (at%) present hard magnet properties when their microstructure consists of a network of cells based on Sm2(Co, Fe)17, limited by boundaries based on Sm(Co, Cu)5 and cut by platelets base

Two dilute alloys with nominal compositions Cu—1.2%Fe2Ti and Cu—0.8%FeTi are studied in the temperature range 500 to 950 °C by electrical conductivity measurements and by transmission electron microscopy (TEM) and field ion microscopy (FIM). Und

The decomposition of two dilute Cu–Co–Ti alloys is investigated by resistivity measurements, transmission electron microscopy, and analytical scanning transmission electron microscopy. The Cu–1%CoTi alloy shows a quasi-binary behaviour. Even af

A bimaterial, consisting of tough and hard layers, was designed to be processed by powder metallurgy. A materials selection software lead to choose steel and cemented carbide for the tough and hard components. To insure the interlayer compatibility,

High performance materials can be obtained by mixing two phases with complementary properties and adequate microstructure. The design and the processing of such materials can be defined using phase equilibrium and stability data. For example, the des
