Abstract

Abstract

Samples for uniaxial tension and spallation experiments of GP1 stainless steel were produced by selective laser melting (SLM). The microstructure of SLM GP1 was characterized by using the optical metallography and electron-backscatter diffraction (EBSD). The tensile mechanical behavior of SLM GP1 as a function of strain rate was studied by using a Zwick-HTM5020 high-speed tensile testing machine and the digital image correlation (DIC) full-field strain measurement method. Significant austenite-to-martensite phase transformation was observed during tensile loading with accompanied plastic strain hardening. Yield stress increases exponentially with strain rate, but at high strain rates (40 and 600 s⁻¹), the yield stress rapidly increases, while the fracture strain decreases significantly. The spallation response of SLM GP1 was investigated by using plate impact experiments. Based on the free-surface particle velocity profiles measured by a displacement interferometer system for any reflector (DISAR), the spall strength of SLM GP1 was found to decrease with increasing flyer impact velocity. Fractography revealed the variation of the fracture mode and fracture mechanism of SLM GP1 as a function of strain rate. Damage nucleates easily at the intersection of the laser melting pool boundary line and grows along the laser pool boundary line. Fracture dimple morphology of the spalled samples is obviously different from that of the samples under the uniaxial tensile loading.
