Orientation-Dependent Deformation Behavior of 316L Steel Manufactured by Laser Metal Deposition and Casting under Local Scratch and Indentation Load

Abstract: This study analyzes the local deformation behavior of austenitic stainless steel 316L, manufactured conventionally by casting and additively by laser metal deposition (LMD). We produced directionally solidified 316L specimens with most grains showing (001) orientations parallel to the longitudinal specimen axis. We conducted nanoindentation and scratch experiments for local mechanical characterization and topography measurements (atomic force microscopy and confocal laser scanning microscopy) of indentation im… Show more

“…Hardness testing is widely used to evaluate the plastic deformability of materials. In the last few decades, nanoindentation testing methods [ 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 ] have been developed and are rapidly becoming widespread for the evaluation of various materials, including steels [ 19 ], tungsten [ 20 ], copper [ 21 ], and NiTi alloys [ 22 ]. This has produced new metallurgical knowledge about nanoscale deformation that is useful for the development of superior materials.…”

“…The LMD technology has significant advantages over traditional forming methods, such as casting [ 10 ]. By adopting this advanced technology, the manufacturing process becomes relatively simple since no mold is required, and its design and manufacturing are integrated, which, in general, saves substantial quantities of raw materials and processing time [ 11 , 12 , 13 ]. Meanwhile, LMD is increasingly becoming the research focus in the field of surface modification of modern materials due to its numerous advantages, such as pollution free and possibility to combine different coatings and substrates [ 14 , 15 , 16 ].…”
