A multi-component Zr alloy with comparable strength and Higher plasticity than Zr-based bulk metallic glasses

Plasticity Improvement of Zr-Based Bulk Metallic Glasses by Adjusting Oxygen Content and Cooling Rate

“…Unlike crystalline alloys, metallic glasses do not have dislocation defects resulted in yielding and plasticity during the deformation process and its plastic deformation is localized or restricted in one shear bands where the deformation becomes so large that it is physically broken suddenly. Usually the compression plastic strain is not more than 2% and tensile plastic strain at room temperature is almost zero 12) . The poor plasticity increases the scattering tendency of mechanical properties which leads to catastrophic failure of BMGs without enough reliability.…”

Atomic oxygen treatment effects on magnetron sputtered Zr–Ti binary films

“…They were also supposed to find applications in aerospace industry as they can combine both the advantage of titanium (low density) and zirconium (corrosion resistance) to fabricate AO-resistant alloy with excellent specific strength. Recently, Zr-Ti based alloy with relatively high strength, which can be compared to those of bulk metallic glass, while keep good ductility was developed [13][14][15]. Meanwhile, as their excellent AO-resistance, zirconium dioxide and titanium dioxide have been widely used as oxygen-resistance coatings [16].…”

The effect of cooling rate on the plasticity of amorphous metal

“…Usually the compression plastic strain is not more than 2% and tensile plastic strain at room temperature is almost zero. That has seriously restricted the application of amorphous metals as structural materials in engineering [9]. In 2007, W.H.…”
