“…Another study made a comparison of the tribological behavior of 17-4 PH SS manufactured via conventional and additive manufacturing methods, and the results showed that AM parts have good potential to be an alternative to counterparts in terms of friction and wear behavior [13]. To summarize, processing conditions can affect the final metallurgical, mechanical, and geometrical properties of the material [14].…”

The 17-4 PH stainless steel is widely used in the aerospace, petrochemical, chemical, food, and general metallurgical industries. The present study was conducted to analyze the mechanical properties of two types of 17-4 PH stainless steel—commercial cold-rolled and direct metal laser sintering (DMLS) manufactured. This study employed linear and nonlinear tensile FEM simulations, combined with various materials characterization techniques such as tensile testing and nanoindentation. Moreover, microstructural analysis was performed using metallographic techniques, optical microscopy, scanning electron microscopy (SEM) with energy dispersive spectroscopy (EDS), and X-ray diffraction (XRD). The results on the microstructure for 17-4 PH DMLS stainless steel reveal the layers of melting due to the laser process characterized by complex directional columnar structures parallel to the DMLS build direction. The mechanical properties obtained from the simple tension test decreased by 17% for the elastic modulus, 7.8% for the yield strength, and 7% for the ultimate strength for 17-4 PH DMLS compared with rolled 17-4 PH stainless steel. The FEM simulation using the experimental tension test data revealed that the 17-4 PH DMLS stainless steel experienced a decrease in the yield strength of ~8% and in the ultimate strength of ~11%. A reduction of the yield strength of the material was obtained as the grain size increased.

Laser additive manufacturing (LAM) has witnessed significant growth in recent years, particularly in the processing of stainless steel due to its corrosion resistance and favorable mechanical properties. In LAM, laser‐directed energy deposition (L‐DED) process offers unique advantages, allowing for the production of large and intricate components with high material utilization and reduced material wastage. Despite its numerous advantages, challenges such as controlling heat input, achieving precise layering, and minimizing residual stresses need to be addressed. The importance of understanding these challenges and mitigation of it, is one of major concern of L‐DED‐processed stainless steel parts. Existing review on metal additive manufacturing has primarily focused on tool steel and stainless steels (austenitic) with an emphasis on process parameter optimization and their effects on deposited part. However, there is a critical gap in understanding how the process parameters impact the evolution of microstructure during deposition, subsequently influencing mechanical and wear properties. Therefore, this review aims to fill that gap by conducting a comprehensive study on L‐DED processed especially 15‐5 precipitation‐hardened and stainless steel (SS) 316L, focusing on microstructural characteristics, texture evolution, microhardness variation, and their influence on mechanical properties and wear resistance. The significance of this review lies in providing valuable insights into the process structure–property relationships of L‐DED processed stainless steel especially in precipitation‐hardened and austenitic grade steel.
