چکیده
With the increasing acceleration of three-dimensional (3D) printing (for example, powder bed fusion (PBF)) metal alloys as an additive manufacturing process, a comprehensive characterization 3D-printed materials and structures is inevitable. The purpose this work was to test highly densified produced from gas-atomized pre-alloyed metallic powders, namely 316L, Ti6Al4V, AlSi10Mg, CuNi2SiCr, CoCr28Mo6, Inconel718, under impact conditions. This done demonstrate best possible performance such materials. Optimized spark plasma sintering (SPS) parameters (pressure, temperature, heating rate, holding time) are applied novel technique metallurgy. densification level, site (imprint) diameter volume, Vickers hardness were studied. comparison 316L stainless steel (1) sintered by SPS (2) manufactured PBF (3) coated physical vapor deposition (PVD) process (thin layer TiAlN) successfully achieved.

متن کاملData on the densification during sintering of binder jet printed samples made from water- and gas-atomized alloy 625 powders
Binder jet printing (BJP) is a metal additive manufacturing method that manufactures parts with complex geometry by depositing powder layer-by-layer, selectively joining particles in each layer with a polymeric binder and finally curing the binder. After the printing process, the parts still in the powder bed must be sintered to achieve full densification (A. Mostafaei, Y. Behnamian, Y.L. Krime...

The high strength carbon steels such as API X65 is widely used to build the pipelines. In this study, the corrosion behavior welds region of the gas pipeline was studied. For this purpose, Shield Metal Arc Welding (SMAW) was used to evaluate the proposed method. The welding processes were performed with E6010, E6013, and ER70S-6 electrodes as filler metal and welding carried out in 3 passes by ...
