Normally, the temperature range is between 550°-565°C. In the second-stage, the activity of nitrogen is lower than that required for the formation of iron nitrides. Thus, iron nitrides, if formed in first stage, dissociate during this period, and the thickness of the white-layer gets reduced from its normal thickness of 0.05 mm to less Properties of Aluminum Alloys at Cryogenic and Elevated Strength at temperatures above about 100 to 200 °C is improved mainly by solid-solution strengthening or second phase hardening. Another approach to improve the elevated-temperature performance of aluminum alloys has been the use of rapid solidification technology to produce powders or foils containing high supersaturations of elements such as
