1. Features and benefits of powder metallurgy
Figure 1 shows a number of production processes used industrially. They will be studied in detail later.
Table 1 illustrates the classic powder metallurgy process (cold pressing and sintering), using the example of bronze self-lubricating bearings. This process, which is by far the most important in terms of tonnage, is an original way of moving from metal powder to ready-to-use parts or components in just a few operations. It can be compared with all the usual processes for shaping objects from liquid metal (molding) or semi-finished products (forming, machining). Among the other processes (hot sintering-compression) shown in figure 1 ,...

Standardization
The particular characteristics of the raw materials and products used in powder metallurgy have made it necessary to create standards for testing methods and specifications, specially adapted to this field of metallurgy. The first standards were published by the Metal Powder Industries Federation (MPIF) in the USA some thirty years ago. Most of them were adopted by the American Society for Testing and Materials (ASTM),...
