Abstract Scope |
Nanoindentation is a versatile method for measuring the microscopic mechanical properties of materials under varied temperatures, albeit only at slow strain rates < 0.1 s-1. Recent developments have increased the permissible constant strain rate to 100 s-1 at room temperature. Here, both capabilities are combined in order to investigate the influence of high strain rates on the strength anomaly of L12 intermetallic compounds. From nanoindentation measurements on Ni3Si under varied temperature and strain rate conditions, it is concluded that high strain rates lead to an extension of the anomalous temperature range. |
