Effect of Hot Rolling Regimes on Solid Solution Structure, State and Properties of Titanium-Stabilized if-Steel Hot-Rolled and Cold-Rolled Product

摘要

Using contemporary physicochemical approaches for predicting phase precipitate stability conditions for laboratory melted metal by optical, scanning, and transmission electron microscopy, local X-ray spectral analysis, testing mechanical characteristics, and determining the content of interstitial elements in solid metal a detailed study is made of the structural state and properties of titanium stabilized IF steels of three compositions. Based on the results obtained, the main requirements for hot-rolled steels are formulated, and the principles and conditions for obtaining good ductility and formability indices are determined for cold-rolled product subjected to recrystallization annealing by a continuous hot-dip galvanizing unit (HDGU) regime.
