Injection molding metallic glass
Abstract
Advances in alloy development have produced the Zr_(35)Ti_(30)Be_(27.5)Cu_(7.5) alloy with a crystallization–glass transition temperature, ΔT, of 165 °C. This alloy's large supercooled liquid region provides the longest processing times and lowest processing viscosities of any metallic glass and was injection molded using tooling based on plastic injection molding technology. Injection-molded beams and die-cast beams were tested in three-point bending. The average modulus of rupture (MOR) was found to be similar, while injection-molded beams had a smaller standard deviation in MOR.
