The Evolution of Microstructures and the Properties of Bulk Metallic Glass with Consubstantial Composition Laser Welding
A Zr55Cu30Ni5Al10 plate-like bulk metallic glass (BMG) was prepared using copper mold suction casting. Additionally, alloy powders with the same nominal composition were synthesized. The alloy powders were welded or melted to the cleaned surface of the BMG with a laser beam acceleration voltage of 60 kV, a beam current range from 60 to 100 mA, a welding speed of 60 mm/s, as well as an impulse w...
متن کاملOxidation Behavior of a Pd43Cu27Ni10P20 Bulk Metallic Glass and Foam in Dry Air
The oxidation behavior of both Pd43Cu27Ni10P20 bulk metallic glass (Pd4-BMG) and its amorphous foam containing 45 pct porosity (Pd4-AF) was investigated over the temperature range of 343 K (70 C) to 623 K (350 C) in dry air. The results showed that virtually no oxidation occurred in the Pd4-BMG at T< 523 K (250 C), revealing the alloy’s favorable oxidation resistance in this temperature range. ...
متن کاملDuctile bulk metallic glass.
We report on experimental evidence of pronounced global plasticity measured in monolithic Pt57.5Cu14.7Ni5.3P22.5 bulk metallic glass under both bending and unconfined compression loading conditions. A plastic strain of 20% is measured, never before seen in metallic glasses. Also, permanent deformation and a strain exceeding 3% before failure is observed during bending of 4 mm thick samples. To ...
متن کاملFriction Welding of Zr55Al10Ni5Cu30 Bulk Metallic Glasses
The friction welding of Zr55Al10Ni5Cu30 bulk metallic glasses (BMG) has been tried. An apparatus for the friction welding of BMGs adopting a pneumatic cylinder and gripper based on a conventional lathe, and a welding process which provides a sufficient cooling rate after welding were devised. Friction time and friction pressure were chosen as the control parameters in the friction welding proce...
متن کاملBulk metallic glass matrix composites
Composites with a bulk metallic glass matrix were synthesized and characterized. This was made possible by the recent development of bulk metallic glasses that exhibit high resistance to crystallization in the undercooled liquid state. In this letter, experimental methods for processing metallic glass composites are introduced. Three different bulk metallic glass forming alloys were used as the...
