Partitioning of the High Strength Steel Contained Ti Microalloy Element at the Temperatures Above and Below Martensitic Transformation Start Temperature (Ms)

In this study, a high strength steel is partitioned at two temperatures (below and over Ms). Structure and main mechanical properties of the samples were studied by scanning electron microscopy, X-ray diffraction, tensile test, microhardness test and pin-on-disk test. The results confirmed that carbon content in austenite phase (Cγ) and R.A (Retained Austenite) volume fraction (Vγ) increased by increasing the partitioning temperature (PT) from a...
