Claim 6:
7. An orientation degree distribution analyzer for calculating an orientation degree distribution from a measurement result of X-ray diffraction and crystal structure information of a measurement target, the orientation degree distribution analyzer comprising:
an information processing apparatus including a main storage device and a central processing unit (CPU),
wherein the CPU is configured to function as:
an acquisition unit configured to acquire first information which is the crystal structure information of the measurement target, second information on an intensity ratio of each diffraction peak of the measurement target and a crystal plane corresponding to each diffraction peak of the measurement target by X-ray diffraction measurement, each diffraction peak of the measurement target being obtained from an X-ray diffraction profile of the measurement target obtained by an X-ray diffraction device, third information on a diffraction range and a diffraction sensitivity, and fourth information on an intensity ratio of each diffraction peak of a randomly oriented sample and a crystal plane corresponding to each diffraction peak of the randomly oriented sample, and input the first information, the second information, the third information, and the fourth information to the main storage device;
an angle calculation unit configured to calculate an angle defined by an orientation plane and a crystal plane corresponding to a diffraction peak of interest from the first information, the second information, the third information, and the fourth information;
an existence ratio calculation unit configured to calculate an existence ratio of particles with crystal planes oriented in directions corresponding to respective diffraction angles of the randomly oriented sample and store the existence ratio in the main storage device;
an orientation degree distribution function setting unit configured to assume a distribution shape of an orientation degree distribution and set an orientation degree distribution function; and
an orientation degree distribution analysis unit configured to calculate the orientation degree distribution based on the first information, the second information, the third information, the fourth information, the angle, the existence ratio, and the orientation degree distribution function.
