Preliminary Investigation On Selective Laser Melting Of 17-4PH Steel Using High laser Powers Of up to 1500W

Not Accessible

Your library or personal account may give you access

Abstract

High laser powers of up to 1500W were used to additively manufacture 17-4PH samples. Porosity was measured using quantitative image analysis technique, and all samples are fairly dense with a maximum of 0.42 percent porosity.
