Micrograin Superplasticity: Characteristics and Utilization
Micrograin Superplasticity refers to the ability of fine-grained materials (1 µm < d < 10 μm, where d is the grain size) to exhibit extensive neck-free elongations during deformation at elevated temperatures. Over the past three decades, good progress has been made in rationalizing this phenomenon. The present paper provides a brief review on this progress in several areas that have been relate...
متن کاملSuperplasticity of Annealed H13 Steel
H13 steel is a widely used hot work die material. A new type of hot working method is imperative to develop complex and precise dies. In this paper, the heat treatment of H13 steel (AISI) was carried out by annealing, the final structure is a point or spherical pearlite, and the grain size is about 30-40 μm. The tensile properties of the annealed microstructure were investigated at 650, 750, an...
متن کاملHydrogen-induced transformation superplasticity in zirconium
Commercially-pure zirconium is alloyed and dealloyed repeatedly with hydrogen at 810 C, thereby cyclically triggering phase transformations between hydrogen-free a-Zr and hydrogen-alloyed b-Zr. Under an externally applied tensile stress, the internal mismatch stresses produced by the a-b transformations are biased, resulting in the accumulation of strain increments after each chemical cycle in ...
متن کاملTRANSFORMATION SUPERPLASTICITY OF SUPER a2 TITANIUM ALUMINIDE
ÐTransformation superplasticity of an intermetallic Ti3Al-based alloy (Super a2) is demonstrated by thermal cycling about the a2/b transformation temperature range under a uniaxial tensile biasing stress. Failure strains up to 610% were recorded at a stress of 3 MPa, compared with 110% for deformation by isothermal creep at the same stress. The strain increment produced during each half-cycle i...
متن کاملEnhanced superplasticity in commercially pure titanium alloy
The superplasticity of commercially pure titanium alloy at high temperature was studied and the dynamic recrystallization phenomenon of the alloy was investigated by using electron back scattered diffraction. A two-step deformation method was used to increase the ductility of the alloy from 188% to 243%. 2004 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
