“…Thin film amorphous alloys, including thin film metallic glasses (TFMG), have several advantages over crystalline alloys, such as high homogeneity, high corrosion resistance, high mechanical strength and soft magnetic properties. [1][2][3] In particular, TFMG has a supercooled liquid region, and it can be formed into a three-dimensional complex structure by heating in this region. 4,5) Recently, various thin film amorphous alloys have been applied to devices.…”

We describe further progress of a previously reported novel crystallization temperature (T x) measurement method applicable for small sample sizes. The method uses thermography and detects T x as a change in emissivity of thin film amorphous alloy samples. We applied this method to various sample configurations of Pd–Cu–Si thin film metallic glass (TFMG). The validity of the detected T x was determined by electrical resistivity monitoring and differential scanning calorimetry (DSC). Crystallization temperature can be detected in all sample configurations; however, it was found that the magnitude of the detected change of emissivity at T x depended on the sample configuration. This emissivity change was clear in the absence of a higher emissivity material. The results suggest that this method can achieve high-throughput characterization of T x for integrated small samples such as in a thin film library.
