Dr. Sarah Anne Smythe

Senior Materials Engineer at BAE Systems

Having completed my undergraduate Masters in Chemistry at the University of Manchester in 2015, I joined the Advanced Metallic Systems CDT at the University of Sheffield.

Current Research

My PhD consisted in working on the Conform™ of various low cost feedstocks – including CP-Ti and Ti-6Al-4V – into wire/rod sponsored by DSTL (Defence Science and Technology Laboratory) and the EPSRC.

Conform™ is a process during which the powder is consolidated through severe plastic deformation and extruded through a profiled die, ultimately wire/rod feedstock. This product can then be used downstream for various applications including springs, wire and additive manufacture.

The project  ultimately aimed to compare small scale testing methods (Arbitrary Strain Path test machine (ASP) and wear tester) and simulations (EDEM) with the Conform™ data and product, giving the ability to determine the ‘conform-ability’ of a material without having to trial. At the same time, however, there was an investigation into the product of the Conform™ process and how this can be impacted by changes in tooling geometries and material.
