Heat treatment response of additively manufactured 17-4PH stainless steel
Materials Characterization, 2023 Unlike conventional 17–4PH stainless steels where thermal treatment (solution annealing + aging) leads to ≈95% martensite and ≈5% retained austenite, additively manufactured 17–4PH stainless steels are not responsive to conventional thermal treatment and

Weldability of 17-4PH stainless steel in overaged heat treated condition
Science and Technology of Welding and Joining, 2006Studies on the weldability of 17-4PH stainless steel, in the 621°C overaged condition, showed that Creq/Nieq ratio higher than 1·5 resulted in primary ferritic mode of solidification in the weld metal. Post-weld aging treatment at 482°C enhanced the strength of the weld joint with corresponding reduction in impact toughness of the weld metal while ...

Using genetic algorithm in heat treatment optimization of 17-4PH stainless steel
Materials & Design, 2007In this investigation heat treatment optimization of 17-4PH stainless steel has been carried out by a genetic algorithm. The optimum technique of heat treatment, adaptive to 17-4PH stainless steel, was obtained from the initial data set by the use of genetic algorithms based on modeling with artificial neural network. The results strongly indicate that
