Abstract
Hardness tests is a simple, cost saving method to estimate mechanical properties of material, requiring commonly available equipment and therefore an attractive method. Relationships between hardness and other mechanical properties exist, the well known one is that of Tabor for the tensile stress evaluation. This chapter emphasizes the grain size effect on the mechanical properties. Small grain size improves static properties such as tensile and yield stresses while large grains enhance creep resistance. A main factor in concentrating on MoSi2 and Ti5Si3 is the availability of data but also due to their excellent high temperature properties. The Hall–Petch relation between hardness and grain size is discussed in this chapter.
