Summary
-
1.
Tensile and torsion tests were carried out on specimens of 12, 21, 31, 37, and 43% porosity, made from reduced iron powder. Values of the ultimate strength, yield point, and ductility characteristics of the materials investigated were obtained.
-
2.
The torsion diagrams of porous iron were plotted.
-
3.
It was found that the straight radii hypothesis applies also in the case of torsion of cylindrical specimens from porous iron.
-
4.
The specific work of rupture of porous iron in torsion is much greater than that in tension.
