Welcome to use TCLab, the following files are generated by TCLab without modification.
= Introduction =
PTCLab is a abbreviation of phase transformation crystallography lab. The purpose of this program is to calculate the transformation crystallgography after a phase transformation and represent the results in graphical way such as in stereo graphic projection. The lattice matching near the interface, the superimposed diffraction patterns and so on can be readily simulated with present program. This program is free, opensource and runnable on multiple platform.
= Function =
The abilities are decribed below:
* The crystal structure
# create crytal sctructure mannually or input from CIF file
# showing orientation relationship between two lattice with euler angle or orientation matrix or miller index expression
# simulation of diffraction patterns and XRD profile
# determine the most close packed planes and directions which are essential for transformation crystallography
Stereo graphic progection
# showing low indexed planes or directions by symmetry opperation
# mannually added poles and big circles
# simulating supperimposed figures according given orientation
# generate the variants of the same orientation relationship according to the lattice symmetry
# commonly niminal orientation relationship such as K-S, N-W for fcc/bcc and Burgers for hcp/bcc, are included and updated.
Transformation crystallography
# mannually and graphically change orientation relationship in both direction and reciprocal space
# calculate orientation relationship according to different criteria, such as O-line method, edge-to-edge method, martensite theory.
# lattice matching in the interface and readily to be output for energy study
# illustrate superimposed lattice mathcing
# near coincidence site lattice percentage calculation within different directions and planes, and results can be shown in stereo graphic proction.
