Microstructure And Mechanical Property

The objective of the research was that analyzed the microstructure and mechanical properties of metal part built by SLM in this paper. The tensile samples were made by SLM, the rupture gotten with tensile experiment was scan by SEM, and the rupture property was analyzed. The results of experiment showed: the parts formed by optimized parameters have a density above 96%, a tensile strength of 635MPa, an extension of 55.679% and an average micro hardness of HV307 for stainless steel powder. It is interesting to find that the phase of the built parts is also austenite by XRD, which is the same as that of the starting material.

Microstructure And Mechanical Property

By means of optical microscope(OM), scanning electron microscope(SEM), X-ray diffraction(XRD) and shear test, the microstructure and mechanical property of 1Cr18Ni9Ti stainless steel brazed joints with BNi-2 filler by electron beam brazing(EBB) and vacuum brazing(VB) are investigated respectively. The results show that, the microstructures of brazed joint with BNi-2 by EBB are mainly solid solutions of Ni. And the microstructures of brazed joint by VB are composed of two parts: one part is a solid solution of Ni, which lies adjacent to base metal; another part is chemical compound structures present in the centre zone of brazing seam. The shear strength of brazed joint by EBB is higher than that of by VB. This is closely related with the microstructures of brazed joint.
