Nd:YAG laser is about 99% of the materials bulk theoretical density, showing promising capabilities for many application areas. The results of an experimental study about SLM of maraging steel 300 on an EOSINT M270 equipped with a fiber laser showed that there is a
Microstructures and mechanical properties of dissimilar This paper presents studies on the microstructure and mechanical properties of AISI 316L stainless steel and AISI 4340 low-alloy steel joints formed by the Nd:YAG laser welding process. The weld microstructures and heat affected zones (HAZs) were investigated. Austenitic microstructures were observed in all of the samples. The sizes of the HAZs changed when the heat input was varied, and
Nd:YAG laser hardening of AISI 410 stainless steel Jul 30, 2019 · In this research, Nd:YAG laser is used to improve the surface hardness of AISI 410 martensitic stainless steel. The effects of Focal point position, scanning speed and pulse width on hardness, the geometrical dimension of the hardened zone, metallographic phases, and corrosion behavior of laser hardened sample in 3.5 wt% NaCl solution were studied.
The microstructure and wear behavior of AISI 304 stainless steel after Nd:YAG pulsed laser surface melting (LSM) were investigated. The microstructural features of the LSM layer were characterized by field emission scanning electron microscope and high-resolution transmission electron microscope. Experimental results showed that the microstructure was obviously refined to the nano- and sub
Plasma/Plume Control for High Power Nd:YAG Laser Welds - This paper reports on an extensive investigation of different nozzle designs, process gases and set-up parameters, specifically for Nd:YAG laser welding of thick section C-Mn steel.
