| description.abstract | HSLA-80 steel, a replacement of HY-80 steel, is widely used in Navy vessels,
where the requirement is good weldability, high strength and high low-temperature
toughness. However, an increase in strength usually causes a decrease in toughness.
Hence there is a need for optimization of the properties. The present work attempts to
optimize the mechanical properties of an HSLA-80 steel through control of heattreatment
variables. The heat treatment region, where the optimum combination of
properties is likely to be obtained, is determined by carrying out single factor
experiments over a wide range of tempering time-temperature combinations.
Subsequently further experiments are done in this zone using statistical design of
experiments. The present work involves quantification of properties by (i) classical
curve fitting technique with data obtained from single factor experiments, and (ii)
forming regression equations from 22 factorial design of experiments. Finally
optimum combination of properties of the present steel has been obtained by Grid
Search technique with a constraint on yield strength. Transmission Electron
Microscopy studies are done, wherever necessary, to understand and correlate the
mechanical properties with the microstructures. | en |
