Kinetic Spraying

NiTiZrSiSn bulk metallic glass powder was produced using inert gas atomization and then was sprayed onto a SS 41 mild steel substrate using the kinetic spraying process. Considering the principle of kinetic spraying and the temperature dependent deformation behavior of the bulk metallic glass, an attempt to change the in-flight particle temperature was tried by modifying the kinetic spraying apparatus. Through this study, the effects of thermal energy of in-flight particle and crystallization degree by powder preheating temperature were evaluated. The deformation behavior of bulk metallic glass is very interesting and it is largely dependent on the temperature and the strain rate. The crystalline phase formation at impact interface was dependent on the in-flight particle temperature. In addition, variations in the impact behavior need to be considered at high strain rate and in-flight particle temperature.

Compression Tests

The mechanical property of Zr52.5Cu17.9Ni14.6Al10Ti5 bulk metallic glass was investigated at different strain-rate range. It is indicated that the yield strength of the Zr52.5Cu17.9Ni14.6Al10Ti5 bulk metallic glass is insensitive to quasi-static strain rates ranging from 4×10-4 s-1 to 4×10-3 s-1. However, plasticity remarkably decreases with increasing strain rate under compression tests. The more shear bands were observed on the side surface of the fractured samples by SEM at low strain rate, which is contributed to the improved ductility.
