Abstract
Fracture is often the culmination of continued deformation Therefore it is probable that a fracture surface may contain an imprint of the deformation processes that were operative In this study the deformation behavior of copperstrengthened highstrength lowalloy HSLA 100 steel has been investigated Systematic variation of the microstructure has been introduced in the steel through various aging treatments Due to aging the coherency size shape and distribution of the copper precipitates were changed while those of inclusions carbides and carbonitrides were kept unaltered Twodimensional dimple morphologies quantified from tensile fracture surfaces have been correlated to the nature of the variation of the deformation parameters with aging treatment
