Induced Crystallization

Pinpoint nano-crystallization in Fe-based metallic glass was achieved by 2.0MV electron irradiation. Circular nano-crystalline structure regions with about 1μm in diameter were formed in the metallic glass and they were well dispersed in the amorphous matrix. In Fe77.5Nd4B18.5 alloy, micrometer order hard magnetic nano-composite region was formed in non-magnetic metallic glass matrix by electron irradiation. Electron irradiation induced crystallization is very effective for obtaining superior functional metallic materials with fine magnetic domains.

This paper presents an improved version and new results on a temperature sensor based on SiC Schottky Barrier Diode (SBD). SiC SBD structures of different areas were packaged in a metallic-glass case. The encapsulated sensor was electrically measured at several temperatures. A good linearity of the forward voltage measured at a constant current versus temperature dependence was obtained in the temperature range of 150-400°C where the sensor is meant to operate. Optical investigation, correlated with electrical measurements, prove the reliability of the sensor structure and of the package solutions at temperatures up to 400°C.
