Chromium Nitride Precipitation Behavior in Weld Heat-affected Zone of High Nitrogen Stainless Steel.

“…Precipitation behavior is reportedly subject to the additivity rule if precipitation rate is controlled by a thermally active process such as Cr diffusion. 11) If so, the occurrence of precipitation can be predicted from the TTP curve and thermal cycle of welding. The thermal cycle was divided into short time segments, Dt i and the precipitation time corresponding to the temperature of each segment C T i was determined from the TTP curve.…”
