WebJun 1, 2010 · So, if you have a punch and some samples of known aluminum alloys of known hardness, you could make punch marks on the known alloy and the unknown one and compare them with a magnifier. Equal hardness should produce equal diameter punches. Be sure to adjust the punch so that the depth does not exceed the diameter of the tip's cone.
WebDec 20, 2024 · In a small punch creep (SPC) test, a miniature disc specimen with typical dimensions of 8–9.5 mm in diameter and 500 μm in thickness is subjected to a constant load that is applied to the material through a punch indenter. As the load is applied to the disc, the material undergoes a biaxial form of deformation prior to the onset of final rupture.
