| Abstract: |
| The bulk amorphous alloys of Cu50Zr42Al8 were prepared by copper mold suction-casting process.The structure and mechanical properties were characterized by nanoindentation technique in as cast and state annealed below glass transformation temperature(Tg),the result shows that the heat treatment make the plasticity increase obviously,while elasticity and hardness reduce respectively. |
