y measurements on steel shot in an
air-blast peening cabinet
Department of Engineering, University of
Warwick, Coventry, UK
The paper reports measurements of shot velocity in an air-blast
cabinet using high-speed photography.
Nominally round chilled steel
shot was used in four sizes, ranging in diameter from 0.025 in.
Nozzle pressures ranged from 15 p.s.i.
to 60 p.s.i.
In addition to the
velocity measurements, data on the rate of shot mass flow was
obtained, making it possible to calculate the total kinetic energy per
second in the shot stream for each condition investigated.
measurement of arc height with Almen A and C strips was undertaken
for some conditions, Coverage measurements were also made on small
round specimens of the aluminium alloy 7075T6.
A small number of
fatigue tests on notched specimens of the same alloy, peened with the
same size of shot but at different pressures showed that ...
