Strain analysis of 15th century guns and projectiles

In this proposal we request 1 day on D2B and 8 days on SALSA to collect compositional and microstructural information on
a series of battlefield artefacts using neutron diffraction. Examination of both projectiles and gun barrels will enable us to
determine phase fractions and characterize surface features (i.e., scratching and wear) on the projectiles and inside of the
barrel formed during firing, in addition to casting flaws (voids) and density gradients in the cast metal during construction.
Knowledge of the strains experienced during construction and firing will prove critical information and add to our
understanding of gunpowder weapons technology and its development during the 15th and 16th centuries.
