摘要

•Extensive study of the effect of energy density on high-strength steel by Laser solid forming (LSF).•The evaluation method of dimensionless heat input Q* is specially introduced.•Under three different heat inputs Q*, microstructures were observed, and the characteristics of their formation were analyzed.•The Q* value has an important influence on the mechanical properties of high-strength steel by LSF.
