Shock properties of AlON

摘要

We performed plate impact experiments on AlON using a VISAR and transverse manganin gauges. The Hugoniot Elastic Limit, σ_(HEL), is 10.5 - 10.9 GPa with a corresponding yield strength of 6.9 - 7.2 GPa. A transverse gauge gives a yield strength of 8.0 GPa for a longitudinal stress of 13.2 GPa which implies that the failed AlON possesses at least its σ_(HEL) strength. At 4.8 GPA the spall strength is 1.7 GPa, while at 9.5 GPA it is 0.14 GPa. There is some evidence that AlON possesses surface fracture zones with a flow stress of 4.8 GPa.
