Single Phase Field

Historically, metals exhibit superplasticity only while forming in a two-phase field because a two-phase microstructure helps ensure a fine, stable grain size. In the U-5.8 Nb alloy, superplastici ty exists for up to 2 h in the single phase field (γ1) at 670°C. This is above the equilibrium monotectoid temperature of 647°C. Utilizing dilatometry, the superplastic (SP) U-5.8 Nb alloy requires superheating to 658°C to initiate the α+γ2 → γ1 transformation at a heating rate of 1.5°C/s. Hence, the U-5.8 Nb alloy exhibits an anomolous superplastic behavior.

Abstract SP 700 is a high strength, beta-rich alpha-beta titanium alloy. It was developed with the following attributes: (1) excellent hot- and cold-workability; (2) enhanced hardenability with a wide range of mechanical properties that can be obtained by heat treatment; and (3) superior superplastic behavior at low temperature (around 1050 K). This datasheet provides information on composition, physical properties, microstructure, elasticity, tensile properties, and bend strength. It also includes information on high temperature performance as well as heat treating. Filing Code: TI-107. Producer or source: NKK Corporation.

Equal-channel angular pressing (ECAP) is a convenient processing method for refining the grain size of bulk materials to the submicrometer level. Metallic alloys processed by ECAP often exhibit excellent superplastic characteristics including superplasticity at high strain rates. This paper summarizes recent experiments designed to evaluate the occurrence of superplasticity in representative aluminum and magnesium alloys and in the Zn-22% Al eutectoid alloy.
