You need to design a metallic glass for use in industry. The glass transition temperature of the metallic glass is 250°C. While in use, the sample will be subjected to a permanent tensile stress for t_use = 6 years and at a temperature of t_use = 230°C. You need to do the necessary creep experiment in the lab to predict the performance of this material by applying the same stress at different temperature and different time. The creep test will be carried out for T_lab = 6 hours. At what temperature, T_lab, can this test be performed in the lab under the same tensile stress?
