Figure 3.8 Nominal tensile strength of a fine Sic powder as a function of the powder bed thick-
ness and bulk density (or porosity E) (From Eckhoff et al., 1978).

Figure 3.9 Combination of shear test data assuming isostaticconditions in tensiletests (Fromfckhoff
et al., 1978).
This emphasizes the need for improved methods for measuring basic properties of pow-
ders, as proposed by Arthur et al. (1985).
An interesting experimentalstudy of the correlationbetween the tensile strength of a
bulk powder and its dispersibilityin a gas was performed by Yamamoto (1990).
