Ti6Al4V titanium alloy is one of the most studied for its properties after additive manufacturing. Due to widely use in medical applications, are investigated various aspects surface layer property improvement and later compared conventionally manufactured Ti-6Al-4V. In this study, corrosion behavior a 0.9% NaCl solution shot peened Ti-6Al-4V prepared using direct metal laser sintering (DMLS) was examined electrochemical testing with forged alloy. Shot peening performed on previously polished samples subsequently treated CrNi steel shots. Two sets pressure were selected: 0.3 0.4 MPa. X-ray diffraction analysis (XRD), micro-computed tomography (Micro-CT), scanning electron microscope (SEM) tests roughness hardness measurements used characterize samples. The conventional characterized by an α + β structure, while had α' martensitic structure. obtained results indicate that resistance higher than DMLSed lowest rates noted untreated surfaces CM/ref DMLS/ref reached 0.041 0.070 µA/cm2, respectively. Moreover, development has influence behavior. Therefore, increasing inferior resistance. However, better performance reported low frequency range. This due refinement grain acquired process. All obtained, related behavior, satisfactory enough all can be as materials suitable implant applications.

Selective Laser Melting (SLM) of 316L stainless steel exhibits great potential prospects for engineering applications due to its high strength, forming freedom, and low material waste. However, the unique processing technology additive manufacturing, challenges related microstructure differences in mechanical properties formed parts are inevitable. To investigate influence building direction grain boundary strength on fracture parameters SLM steel, electron backscatter diffraction (EBSD) experiments were conducted characterize stainless-steel specimens. A representative volume element (RVE) model reflecting was established based a combination crystal plastic finite method (CPFEM) UMAT subroutine technology. The plasticity determined by comparing results tensile tests. Cohesive elements employed inserted at boundaries polycrystalline RVE simulate intergranular behavior under uniaxial loading. damage mechanisms microscale analyzed. simulated stress–strain curves good agreement with experimental results; hence, combined CPFEM is suitable characterizing response steel. revealed that cracks initiate stress concentration sites propagate along increasing external load, ultimately leading rupture. Additionally, influences location microcracks their propagation significantly.
