x wt.% B4C/Ti6Al4V titanium matrix composites were prepared by selective laser melting (SLM) technology. The microstructure and mechanical properties of the SLM-formed heat-treated samples studied in detail. results indicated that an in-situ reaction occurred during SLM process, producing acicular TiB, whisker TiB granular TiC. microhardness melted sample increased with increasing B4C content. When (B4C) is 0.05, properties, i.e., compressive strength, strain, tensile strength elongation,...
Additive manufacturing is capable of achieving sophisticated geometries not attainable through conventional methods and it especially attractive to fabricate conventionally hard-to-process Nb alloys via additive for aerospace applications. In this study, a Nb521 (Nb-5W-2Zr-1Zr) alloy with relative density 99.0% was successfully processed by Selective Laser Melting (SLM). The SLM microstructure characterized, showing high dislocation density, cell structure large population low-angle grain...
In this study, we designed the processing windows for laser powder bed fusion (LPBF) of Ti-6Al-4V (Ti-64) alloy by using central composite design and made a detailed investigation into influence parameters on defects. The purpose is to investigate effect defects mechanical properties. It was found that insufficient energy density could lead formation lack (LOF) produce non-melted powders surface, while excessive cracks were detrimental performance. addition, microstructural evaluation...
Magnesium–lithium alloys are arguably the lightest metal structural materials but have low strength. In order to increase strength, friction stir processing (FSP) is applied a hot-rolled Mg-10Li-3Al-3Zn (LA103Z) sheet study effects on microstructure and mechanical properties. this study, strengthening mechanisms of various FSP regions an Mg-Li alloy were clarified by combination numerical simulation experimental method. Based ANSYS APDL, finite element model with moving heat source...
High-temperature fatigue properties are critical for laser powder bed fusion (LPBF) fabricated Nickel-based superalloy Hastelloy-X (HX) used in aero engines. In this study, superior high-temperature high-cycle of LPBF HX were achieved. The detailed investigations show that the grain boundary oxidation promoted by different deformation modes between neighboring grains, despite reduced oxygen-related damage coarser microstructures, potential causes inter-granular crack initiation and...
The unique thermal history of selective laser melting (SLM) can lead to high residual stress and a non-equilibrium state in as-fabricated titanium alloy components hinders their extensive use. Post heat treatment, as classical effective way, could transform α’ martensite achieves desirable mechanical performance SLMed Ti alloys. In this study, we aimed establish the correlation between microstructure performances Ti6Al4V (Ti-64) by using different treatment processes. columnar prior β grain...
The complex aircraft components are difficult to manufacture because of their complicated shapes and high requirements mechanical properties. Besides, those usually need a functional coating layer on the surface improve reliability, which adds an extra production cycle after manufactured. In this study, integrated forming process was proposed complex-shaped impeller together with using hot isostatic pressing (HIP). new process, HIP mold graphite core pre-deposited Ni designed conducted...
