Overview

Demonstrates how chemical composition affects microstructure and hardness in L-PBF 316L steel, indicating significant implications for manufacturing quality.

Key Points

  • To investigate how different chemical compositions of feedstock powders affect the solidification microstructure and mechanical properties of L-PBF 316L stainless steel.
  • Utilized laser-powder bed fusion technology for manufacturing 316L stainless steel components.
  • Varied chemical compositions of raw powders from different producers while keeping processing parameters constant.
  • Employed advanced microscopic techniques to analyze microstructural characteristics.
  • Identified variations in the chemical composition lead to changes in solidification mode.
  • Noted significant differences in grain shape, size, and boundary types as a function of composition.
  • Revealed that these changes affect the mechanical performance of the manufactured steel.
