Abstract
Mechanical alloying approach, using a low-energy ball milling technique was employed for synthesizing metallic glassy Ti40.6Cu15.4Ni8.5Al5.5W30 alloy powders. The powders of the product obtained after 200h of milling possessed high thermal stability, characterized by a wide supercooled liquid region of 90K and crystallization temperature began at 827K. The powders were successfully consolidated into full dense bulk metallic glass at temperature laid above its glass transition temperature, using spark plasma sintering technique. The as-consolidated bulk metallic glassy alloy possessed extraordinary mechanical properties, such as high values of microhardness (∼11.61GPa). Moreover, the measured friction coefficient of this new bulk metallic glassy alloy was 0.32.
