The study of fracture toughness of pure Al, Cu, Ni and Ti deposited by cold spray was
performed in order to obtain a fundamental understanding of the damage process and
quantify the material performance. Rectangular specimens cut from self-standing deposits
with fatigue pre-cracks were tested in three-point bending. The K IC values were obtained
from JR curves following the ASTM E1820 standard. The stress–strain behavior of the tested
material was obtained from supplementary four-point bending. The cold spray deposits …
