200º Heating/Cooling Stage Making a Point in the Nanomechanical Community
Introduction

What happens to your materials
during temperature change? With
the Hysitron thermal stage,
nanoscale testing of materials at
non-ambient temperatures is now
possible. In present day
applications, materials are rarely
utilized at room temperature alone.
Meanwhile, temperatures may have
drastic effects on the mechanical
properties and behaviors of
materials. Using Hysitrons
nanoindentation, scratch, and
nanoDMA
testing techniques in
conjunction with precise
temperature control will provide you
with a more comprehensive
understanding of how your materials
behave in real-life environments.

Heating/Cooling

Temperature control is
accomplished by incorporation of
a Peltier thermal element and a
resistive heater that are located
beneath the specimen. Peltier
thermal devices allow both
heating and cooling, which allows
this unique thermal stage to both
heat and cool materials over a
broad range of temperatures. The
temperature of the sample stage is
controlled with extreme precision
by a fully calibrated PID feedback
controller. Hysitron has
developed a software package,
TriboTC, which allows the user
to dynamically change and
monitor temperatures during
testing.
Hysitrons new Thermal Stage, heat shield and extended
ceramic tip isolates thermal energy to the sample.
Thermal stability

Elevated temperature testing often
affects the testing instrument as
well as the sample to be tested;
therefore, steps have been taken to
thermally isolate the system from
the effects of the temperature
stage. The indenter probe shaft
has been replaced by an
insulating, low thermal expansion
ceramic that minimizes the affect
of the temperature differential
between the tip shaft and the
sample. Insulating and heat
removal components have been
added that isolate the temperature
stage from the TriboIndenter
platform on which it is placed.
Similar thermal components have
been placed between the sample
and the transducer to thermally
shield the measurement transducer
from thermal convection from the
sample and thermal stage. During
cooling of samples, a user
specified gaseous delivery system
may be introduced that minimizes
condensation and freezing of
water on the surface of the
sample.
