Randomized trial evaluates tensile performance in duplex stainless steel, highlighting effective predictive methods.

This study aims to predict the mechanical properties of heat-treated duplex stainless steel fabricated by laser powder bed fusion.
Evaluated tensile performance of duplex stainless steel under three conditions: as-built, stress-relieved, and aged.
Conducted mechanical testing, scanning electron microscopy, and hardness measurements.
Employed statistical methods like analysis of variance and machine learning models for analysis.
Tuned support vector machine and extreme gradient boosting models achieved R2 values of 0.941 for yield strength and 0.910 for % elongation.
Significant differences in mechanical properties were confirmed among heat treatments using multivariate analysis.
Identified yield strength, elongation, and grain size as key discriminants for predicting mechanical performance.
