Effect of Silver Content in Zr55Cu30Ni5Al10-xAgx Alloys on the Supercooled Liquid Stability Analysed by TTT Diagrams

The aim of this work was to investigate influence of silver content on the supercooled liquid stability of Zr55Cu30Ni5Al10-xAgx (x = 0-4) alloys which exhibit the compressive strength above 2 GPa.Series of isothermal heating examinations were performed by the differential scanning calorimeter.Based on results, time-temperaturetransformation diagrams were created.For the practical testing of time-temperature-transformation curves, thermoplastic deformations in the range of supercooled liquid region were performed.The temperature and time of deformation were controlled according to research results.The time-temperature-transformation diagrams allow for deformation of the samples in a range of stress 40-100 MPa and do not change the structure of the processed samples.
