Detection of embrittlement in low alloy steels due to thermal aging by small punch test

The applicability of miniaturised small punch tests (SPT) to capture thermal aging degradation of two commonly used low alloy steels (LAS) viz. Mn-Ni-Mo and Cr-Mo-V steels, was investigated. This was done by comparing the SPT results to the results of the conventional Charpy V-notch (CVN) tests, fra...
