Abstract
Sintered iron rings exhibiting a wide range of total porosity were produced by different fabricating techniques and their mechanical strengths evaluated by radial-crushing tests. The significance of this form of test is discussed and the experimental results considered in terms ofthe variations in the form of the porosity present in the specimens, as well as its total volume.
