Principle 3
On the porous sintered metal pipes take the ring-like, radial force is applied to the ring-like from the inside until the sample is pulled off, according to the tensile force and the cross-sectional area
The calculated strength is sintered tensile strength of the metal ring porous material.
4 Sample
4.1 sample is to be a ring, diameter size range should be 50mm ~ 100mm, wall thickness should be 1.0mm ~ 5.0mm, height should be
10mm ~ 20mm, see figure 1.
Millimeters
