Boride formation behaviour and their effect on tensile ductility in cast TiAl-based alloys

Autor: Jing Li, Spencer Jeffs, Mark Whittaker, Nigel Martin

Publikováno v: Materials & Design, Vol 195, Iss , Pp 109064- (2020)

Boron has been used to refine the microstructures in TiAl castings, such as low-pressure turbine (LPT) blades, to improve mechanical properties. However, boride precipitates with undesirable morphologies could reduce ductility and even entirely remov

Autor: Spencer Jeffs, Robert Lancaster, Gareth Davies, William Hole, Brenna Roberts, David Stapleton, Meurig Thomas, Iain Todd, Gavin Baxter

Publikováno v: Materials, Vol 14, Iss 18, p 5376 (2021)

To fully exploit the benefits of additive manufacturing (AM), an understanding of its processing, microstructural, and mechanical aspects, and their interdependent characteristics, is necessary. In certain instances, AM materials may be desired for a

High Temperature Deformation Mechanisms in a DLD Nickel Superalloy

Autor: Sean Davies, Spencer Jeffs, Robert Lancaster, Gavin Baxter

Publikováno v: Materials, Vol 10, Iss 5, p 457 (2017)

The realisation of employing Additive Layer Manufacturing (ALM) technologies to produce components in the aerospace industry is significantly increasing. This can be attributed to their ability to offer the near-net shape fabrication of fully dense c

Structural Integrity of an Electron Beam Melted Titanium Alloy

Autor: Robert Lancaster, Gareth Davies, Henry Illsley, Spencer Jeffs, Gavin Baxter

Publikováno v: Materials, Vol 9, Iss 6, p 470 (2016)

Advanced manufacturing encompasses the wide range of processes that consist of “3D printing” of metallic materials. One such method is Electron Beam Melting (EBM), a modern build technology that offers significant potential for lean manufacture a
