## Title

- title: Morphological and Crystallographic Features of α' Martensite in Binary Ti–Hf
    Alloy
  title_type: original
  lang: en

## Description

- description: We investigated the morphological and crystallographic features of
    α' martensite variants in Ti-25 at% Hf and Ti-50 at% Hf alloys by transmission
    Kikuchi diffraction and transmission electron microscopy. On the basis of the
    results, we also discussed the formation process of variants and the self-accommodation.
    Both alloys, after solution-treatment and quenching in ice water, consisted of
    α' martensite with a hexagonal close-packed structure. The α' martensite exhibited
    a larger plate-like morphology several micrometers in length, along with a finer
    morphology with a width of tens of nanometers. The formation of {101-1}α' twins
    was induced within a larger correspondence variant (CV) as a lattice-invariant
    shear (LIS), and {101-1}α' twins were also the boundaries bounded two neighboring
    CVs. In formation process of the martensite variants of Ti–Hf alloys, a larger
    CV with a plate-like morphology is first formed with a {101-1}α' twin as an LIS
    in a β parent phase; finer CVs are subsequently generated from the step-like boundary
    with the {101-1}α' twin plane, followed by the formation of a pair of CVs with
    the twin plane to relax the transformation strain.
