Bi2O3 is an excellent ceramic candidate for transformation-mismatch plasticity because of its low melting point, its allotropic nature and the rapid creep rate of its high-temperature d-phase. Transformation-mismatch plasticity, which has been reported in many polymorphic metals, alloys and composites [1], is a deformation mechanism taking place during a phase transformation: internal mismatch ...

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 ...

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...
