Observation of Nb grain boundary segregation and Nb(C,N) precipitation on the austenite grain growth by HT-LSCM

In continuous casting and heat treatment processes, the monitoring of the austenite grain size and homogenous size distribution is an important factor for efficient production of high-quality steel. The austenite grain size is a precursor for the final mechanical properties. The right grain size avoids production related issues like hot tearing, creep [...]
