In this research, the behavior of austenite grain growth at a high niobium low carbon (High Nb low C) and low Nb high C HSLA steel was evaluated, and the result was compared with other investigation. The results found that the austenite grain growth at high Nb high C steel was slower than the growth at a low Nb low C steel.[plate]Change of tensile behavior of a high strength low alloy [steel]The steel under investigation with the composition as represented in Table 1 was molten in a vacuum induction furnace. The as forged blocks with the size of 80 mm × 70 mm × 60 mm were hot rolled to 7 mm thick plates in the process as shown in Table 2 after soaking at 1150 °C for 2 h.

All experiments were performed with constant laser power of 1.5 kW and welding speed 20 mm s 1.This combination results in heat input (laser power divided by welding speed) 75 J mm 1 for single laser welding. Argon with the flow of 18 l min 1 was applied as a shielding gas
In heavy steel sections, fundamental properties such as strength and toughness are improved remarkably by refining and homogenizing the final ferrite microstructure. Conventionally, the microstructural refinement of the final ferrite depends mainly on the austenite grain size, morphology and composition prior to the phase transformation as well as the cooling rate during the transformation.[plate]Synchrotron Investigation on the Precipitation Behaviour [steel]The precipitation and dissolution behavior of niobium carbo nitrides is of particular interest for many technical applications. Niobium microalloyed high strength low alloy (HSLA) steels are widely used in civil construction, automobile and line pipe applications. These steels rely on thermomechanical processing.
