DETAILED DESCRIPTION OF THE INVENTION For example, in the case of an iron plate or other thin plate metal material or powdery inorganic substance, the crystal structure at high temperature is observed by using X-ray diffraction, and at the same time, the sample is rapidly cooled to obtain high temperature. Analysis is required when the state of is fixed. However, in the past, it was difficult to heat the sample to a high temperature and to cool the sample extremely rapidly, which required a complicated and large-sized apparatus and could not obtain sufficient results. Therefore, according to the present invention, a thin plate-shaped sample is heated to several hundreds to 1,000 degrees or more by an extremely simple and compact device, and the diffraction angle is measured by irradiating the sample with X-rays, for example, several thousands per minute. (EN) A sample heating device capable of fixing a crystal structure and optically observing it or studying its change by rapidly cooling a sample at a speed of 10 degrees.

The present invention relates to a sample holding mechanism for an X-ray diffractometer, in which a band-shaped resistor is attached to the tips of both legs of a U-shaped base and one of the legs is rotatably held to bend or break as the resistor expands or contracts. In addition, a heating current is passed through the resistor by inserting an electric insulator at an appropriate position on the base to heat the resistor to several hundred degrees to 1,000 degrees or more. Also, a cooling water flow path is provided on both legs of the base to prevent the temperature of the base from rising, and a nozzle for spraying a cooling fluid on the back surface of the strip-shaped resistor to rapidly cool it is provided. ,
The resistor itself is used as a sample, or a powdery or thin plate-like sample is attached to the resistor and irradiated with X-rays, and the diffraction X-rays are detected to measure the diffraction angle. Therefore, the sample and its holding portion can be formed in a very simple and small size, and the X-ray diffraction angle can be measured in such a state that the sample is heated to an extremely high temperature, or the sample once heated can be heated to, for example, about 6000 degrees per minute. It is also possible to perform optical observation by rapidly quenching at a high speed and fixing the crystal state at high temperature. Further, it can be used for releasing the lattice strain in the recrystallization process or for observing the crystal orientation change during the phase transformation.

FIG. 1 is a longitudinal sectional view of an embodiment of the present invention, and FIG. 2 is a front view thereof, in which a strip-shaped resistor 2 such as a steel plate is arranged at the tips of both legs of a mounting base 1 of a U-shaped sample, It is designed to be held down by the press fitting 3 and tightened with the screw 4. In addition, cooling water passages 5 are provided in the both legs, cooling water inflows or outflows 6 are formed at both ends thereof, and a thermocouple contact 7 for temperature measurement is provided on the back surface in the central portion of the strip-shaped resistor 2. It is attached. Further, one leg 8 of the U-shaped base 1 can be slightly rotated in a plane including the base by connecting its base end to a central piece of the base by a shaft 9. . In addition, an electrical insulator 10 is inserted in the center piece of the base 1 to insulate between the legs, and a heating current terminal is provided at the base end of the legs.
11 is provided and is connected to the power source by the lead wire 12. Further, a nozzle 13 for spraying a cooling fluid such as low temperature air or nitrogen on the rear surface of the central portion of the resistor 2 at a high speed is attached to the central portion of the base 1. In the above embodiment, the central portion of the strip resistor 2 itself is used as a sample.
For example, when performing X-ray diffraction measurement on other powdery or thin plate-shaped samples, a partial front view is shown in FIG.
As shown in the vertical sectional view in the figure, a shallow recess 14 may be provided in the center of the front surface of the resistor 2 and the sample 15 may be filled in the recess as required. Further, FIG. 5 is a plan view of an apparatus for performing X-ray diffraction measurement by installing the sample mounting base 1 as described above on the rotary table 17 of the goniometer 16, and showing the X-ray tube 18 installed on the side of the goniometer. The X-ray x is projected onto the central portion of the resistor 2, and the diffracted X-ray x ′ is detected by the X-ray detector 19 which rotates at twice the angular velocity of the turntable 17, thereby measuring the diffraction angle. If necessary, the base 1 on the rotary table 17 is housed in a vacuum device to prevent X-ray attenuation and scattering.

As in the above-mentioned embodiment, the device of the present invention heats by directly applying a current to the strip-shaped resistor formed by the sample or by passing a current to another strip-shaped resistor attached with the sample. The temperature of the sample can be raised.
Also, because one leg of the U-shaped base is rotatable,
There is no risk of the resistor being bent or cut due to the expansion and contraction of the resistor, and it is possible to prevent the sample position from changing. Further, when cooling the sample, the nozzle 13 is connected to, for example, a nitrogen cylinder, and low temperature nitrogen is blown to the back side of the strip-shaped resistor 2. At this time, the gas blown from the nozzle rapidly expands, and the temperature sharply drops due to this expansion, so that the heated resistor 2 is cooled very effectively and efficiently. That is, the temperature of the heated sample is
Since the crystal state is rapidly lowered at a speed of about 6000 degrees and the crystal state at high temperature is fixed, it is possible to compare, for example, X-ray diffraction data and optical observation of the fixed crystal state.
