چکیده مقاله:
Materials’ mechanical properties transform at various temperatures. Transformation-induced plasticity (TRIP) makes the material’s properties change. The current study aims to investigate how the small punch test (SPT) can reveal the TRIP in steel. To this end, first, two SPT specimens were prepared and tested at ambient temperature and -۱۹۶ degrees using liquid nitrogen. A considerable difference in force-displacement curves was seen, revealing a great increase in ultimate stress at -۱۹۶ degrees. This change proves that the TRIP phenomenon is seen in the SPT.
