用高分辨中子衍射法研究了不同塑性应变的异地压缩试样在等温淬火球墨铸铁(ADI)中的应变诱发马氏体相变。此外,还用中子衍射法测量了体织构,计算了不同应变水平下铁素体和奥氏体相的取向分布。将详细的织构信息与中子衍射谱相结合,对于马氏体相的定量分析和马氏体相的提取是必不可少的。ADI中应变诱发的马氏体量与等温温度和变形量有关。
The strain induced martensitic transformation in austempered ductile iron (ADI) has been investigated using high resolution neutron diffraction on samples compressed ex-situ to different plastic strains. In addition bulk texture measurements using neutron diffraction have been performed to calculate the orientation distribution of ferrite and austenite phases for different strain levels. Combing the detailed texture information with neutron diffraction pattern proved to be essential for quantitative phase analysis and extraction of martensite phase fractions. The martensite content induced by strain in ADI depends on austempering temperature and degree of deformation.
