The orientation relationship of M_6C carbides precipitated from weld metal in a 2.25Cr\|1Mo steel welded joint after creep;

Orientation Relationship of Bainitic Transformation in a Cu Zn Al Mn Alloy;

Analysis on orientation relationship of plate martensite phase transition;

The micro-appearance feature, the formation of twin lines of monoclinic, the phase transformation and the crystal orientation relationship of ZrO_2 laminated ceramics were studied by scanning electron micro scope(SEM),transmission electron microscope(TEM), X-rays instruments, etc.

The multi-orientation relationships and {112}γ pseudo-twin relationship of three types of 7-Mg17Al12 precipitates (bcc) formed in an aged AZ91 Mg-Al alloy were studied using TEM.

By electron diffraction analysis,it is identified that the alloy phase has a face center orthogonal structure and there are some orientation relationship between the Mg ma.

There are K-S and N-W orientation relationships between the bainitic ferrite and the austenite and there is only N-W relationship between them.

Some M23C6 transformed into M6C, which always kept [114]M6c//[11O] A//[110]M23c6 twin orientation relationship with austenite a.

This paper analyzes the vertical relations and the degree of integration of domestic construction enterprises at first.
