Mechanical properties of NiFe based alloy glasses

TLDR: In this article, the ductility and tensile strength of Ni-Fe based alloy glasses prepared by the "roller quenching" technique were investigated and it was suggested that the hot rolling of the alloy during quench is responsible for the brittle behavior.

Abstract: The ductility and tensile strength of NiFe based alloy glasses prepared by the ‘roller quenching’ technique were investigated. These alloy glasses are intrinsically ductile and possess a high tensile strength. However, the mechanical properties of glasses which are predominantly Fe are very susceptible to the quenching conditions, and such glasses tend to be brittle. It is suggested that the hot rolling of the alloy during quenching is responsible for the brittle behavior. Tensile strengths as high as 230 000 psi were obtained for the NiFe based alloy glasses.
