Special Issue Information

Dear colleagues,

The market share of sintered metallic materials is constantly increasing and is a permanent stimulus for the development of new materials and new technologies. From the beginning, powder metallurgy was used to produce materials that could not be produced otherwise. However, the obvious advantages of the method have meant that today many applications make use of powder metallurgy, for very different purposes. What makes this technique so attractive is the possibility to control the composition of the starting powders, altering their size, morphology, and internal structure (in micro or nanoscale), which allows some control of the properties of the final products. The forming and sintering process, carried out in several stages or all at once, normally requires the concurrence of pressure and temperature, but more recently it can also include other factors such as electric and magnetic fields, microwave, or laser light. The ultimate goal is usually to obtain fully dense materials with a net shape or near-net shape.

Naturally, these manufacturing and processing routes are becoming increasingly complex. The modeling and simulation of these processes offer virtual tools to assist in the development and optimization of the process, and reduce the cost of experimental testing and material waste.

In this Special Issue, we welcome papers that focus on the forming and sintering methods of metallic powders, with an emphasis on the simulation of such processes. Traditional routes are included, but also the most recent techniques, aimed at producing high-performance products.

Abstract: A commercially pure (c.p.) nickel powder was consolidated by Medium-Frequency Electrical Resistance Sintering (MF-ERS). In this consolidation technique, an external pressure and the heat generated by a low-voltage and high-intensity electrical current, are simultaneously applied to a powder mass. In this work, the effect of current intensity and heating time on the global porosity values, the porosity and microhardness distribution and the electrical resistivity of the sintered compacts was studied. A nickel powder (with a high tap porosity) and a low working pressure (only 100 MPa) were chosen in order to be able to obtain compacts with different levels of porosity. The properties of the compacts consolidated by MF-ERS are compared with the results obtained by the traditional powder metallurgy route, consisting in cold pressing and furnace sintering. A universal equation to describe the porosity influence on the all analyzed properties of the powder aggregates and sintered compacts is proposed and validated.
