Abstract Scope |
The mechanical and microstructural properties of many materials depend on temperature. These thermal properties dictate material behavior during thermal fluctuations, such as elevated temperature. A new device is presented to provide in situ sample heating up to 500 °C in the Xradia Ultra family of X-ray microscopes with spatial resolutions down to 50 nm. The in situ heating unit utilizes Micro-Electro-mechanical Systems (MEMS) technology whereby the heater is built directly onto a silicon and SiN windowed chip, allowing for high X-ray transmission. Various material science applications ranging from soft polymers to metal alloys are discussed and we present initial results demonstrating the utility. The in situ heater provides the ability to perform heating experiments without the need to remove or remount the sample. This allows for continuous imaging during temperature ramp, at target temperature holds, and temperature step / cycling to probe dynamic changes in the sample, in 3-dimensions. |
