Superplastic behaviour of two extruded gamma TiAl(Mo,Si) materials

, 2005
The superplastic properties of two intermetallic Ti–46.8Al–1.2(Mo,Si) and Ti–46Al–1.5(Mo,Si) (at.%) materials produced by arc melting and processed by hot extrusion in the temperature range between 1200 and 1250 °C were studied.

Deformation mechanism maps for superplastic materials

Sufficient experimental results are now available for the construction of deformation maps for two superplastic materials, Zn-22% Al and Pb-62% Sn, and (ii) when plotted in the form of grain size versus stress, the maps for these two alloys provide ...

Greener manufacturing: Superplastic-like forming

, 2012
Conventional superplastic forming (SPF) is normally conducted at a slow forming rate (10-3 s-1 or slower) and high temperatures (typically 773 K or higher for aluminum alloys), which is not attractive for wider applications.

Option Defining Relations Sourcewise-Type Using an Internal Time in the Mechanics of Superplastic Materials

Механика машин, механизмов и материалов, 2010
It is existed the sourcewise form of a general relation between stresses and strains in the A.A. Ilyushin theory of elastoplastic processes. A particular case of such approach is the endochronic theory of plasticity, formulated by Valanis. In this theory
