Researchers from the UAB and the ICN2 have developed a methodology that makes it possible for the first time to observe under the microscope, in real time, what happens when glass is heated and changes to a supercooled liquid phase, known as the "glass transition". The research, published in Nature Physics, is of great importance for the cryopreservation of proteins, cells and living tissues, for the manufacture of drugs and electronic devices, and for tissue engineering, where this glass-to-liquid transition plays a key role.
The oxidation behavior of Cu-bearing 301 austenitic stainless steels (ASSs) heated to 1150 ℃ in air was studied by differential scanning calorimetry. The results show that the addition of 1.0–1.8 wt% copper to 301 stainless steel can significantly improve its high-temperature oxidation resistance. The formation of high-temperature oxides scales occurred in a narrow temperature range and was delayed. The temperatures corresponding to the main exothermic peak had increased by more than 100 ℃. A more uniform, denser and thicker protective Cr-rich oxidation scale was formed rapidly on the steel surface, and could efficiently prevent further oxidation. No copper enrichment occurred on the steel surface during the heating process.
