High-temperature nanoindentation testing of fused silica and other materials
This paper describes a new high-temperature stage for small-scale mechanical property
testing. This allows the determination of the load-penetration curve of a diamond tip in a
temperature range extending from room temperature to 400° C. Both sample and indenter
can be heated separately. Indentation curves show that very low thermal drift can be
achieved. Nanoindentation results are presented for gold, soda—lime glass, fused silica and

Abstract
This paper describes a new high-temperature stage for small-scale mechanical property testing. This allows the determination of the load-penetration curve of a diamond tip in a temperature range extending from room temperature to 400°C. Both sample and indenter can be heated separately. Indentation curves show that very low thermal drift can be achieved. Nanoindentation results are presented for gold, soda—lime glass, fused silica and a polyimide and compared with existing microscale and bulk mechanical property data where available. Results from fused silica show that its mechanical properties exhibit a completely different temperature dependence from those of soda-lime glass, as expected since fused silica is an anomalous glass.
