(i) Describe how a metal could be forced into a glassy state. How do the properties of a metallic glass vary with the direction in which the sample is tested? Describe, with justification, how such a metal might be used in an electrical application. [50%] (ii) Figure 1 shows a differential scanning calorimetry (DSC) trace during the heating of a sample of an iron-rich metallic glass at 10Kmin1. Explain the step-like change at about 520K. What does the inverted peak that begins at about 700K indicate is happening to the glass? If the sample weight is 0.1mg, calculate the latent heat per gram, associated with the event beginning at 700 and ending at 900K.
