Micro-architectured, precipitation-strengthened structures were created in a new process combining weaving, gas-phase alloying, diffusion, and precipitation. First, high-ductility Ni-20 wt pct Cr wires with 202 μm diameter were braided, or non-crimp orthogonal woven, into three-dimensional structures. Second, these structures were vapor-phase alloyed with Al at 1273 K (1000 °C) by pack cementation, creating uniform NiAl coatings on the wires when using a retort. Also, solid-state bonding was… 

Mechanical Behavior of Three-Dimensional Braided Nickel-Based Superalloys Synthesized via Pack Cementation

Braided tubes of Ni-based superalloys are fabricated via three-dimensional (3-D) braiding of ductile Ni-20Cr (wt pct) wires followed by post-textile gas-phase alloying with Al and Ti to create, after

Processing and Characterization of Liquid-Phase Sintered NiTi Woven Structures

Porous NiTi is of interest for bone implants because of its unique combination of biocompatibility (encouraging osseointegration), high strength (to prevent fracture), low stiffness (to reduce stress

Iron and Nickel Cellular Structures by Sintering of 3D‐Printed Oxide or Metallic Particle Inks  

Inks comprised of metallic Fe or Ni powders, an elastomeric binder, and graded volatility solvents are 3D‐printed via syringe extrusion and sintered to form metallic cellular structures. Similar

Microstructural evolution mechanism during brazing of Hastelloy X superalloy using Ni–Si–B filler metal

Evolution of aluminide coating microstructure on nickel-base cast superalloy CM-247 in a single-step high-activity aluminizing process

This study deals with the aluminizing of a directionally cast Ni-base superalloy, namely CM-247, by a single-step process using a high-activity pack. It is observed that significant incorporation of

Surface Properties of 316L Austenitic Steel Improved by Simultaneous Diffusion of Titanium and Aluminium

Samples of 316L austenitic steel were submitted to a thermochemical treatment which implies surface diffusion of Al and Ti. The technique of pack cementation with NH4Cl as activator was employed. The

Mechanisms of formation of diffusion aluminide coatings on nickel-base superalloys

Studies on microstructures and compositions of model diffusion aluminide coatings coupled with existing information on diffusion in nickel-aluminum intermetallic compounds indicate that only two
