Describe one way that you could improve the green strength of a steel powder part if the green density must remain constant?

Solution

Green strength can be improved by various methods including:

The first two methods would obviously have some effect on the density.

One of the few methods to improve the green strength would be to improve the physical contacts of the particles on atomic level. This is usually done during the powder production phase of powder metallurgy. If the particles are of irregular sizes, then the surface contact between them increases which further results in better cohesive forces among those particles. So any methodology which results in irregular particle size would provide better green strength than the conventional processes. One of the example of solid state reduction.
