Definitions
- the subject of the invention is a compression device which guarantees pure compression of an anti-LLon screen having two parallel faces between which the press is compressed without any prior adjustment operation of the press being necessary even at high temperature and for heavy loads.
- the classic mechanical testing machines used for this kind of testing normally require delicate adjustments to obtain a rigorous uniaxial solicitation. That is to say a pure and uniform compression on L * sam i L Lon. They are essentially L in general composed of two parts which face each other (by plane faces) and one of which is a fixed support and the other a movable piston. The sample is compressed by the advance of the piston, but long and difficult operations are necessary to restore correct alignment of the two parts.
- the support and the piston are each composed of two parts joined by a respective rotuLe, the parts which carry the plane faces being formed so as to slide the 'one in the other.
- the compression device is made of graphite with a low ash rate (to avoid degassing at high temperatures), because this material has good mechanical qualities which improve at high temperature.
- the flat faces may however advantageously belong to ceramic anvils, for example zirconia, to ensure good mechanical strength at high temperature.
- the testing machine comprises an oven enclosure 1 formed by two cylindrical half-shells closing one on the other and only one of which is shown here.
- This half-shell is pierced with two diametrically opposite openings 2 and 3: a piston rod 4 fixed to a frame 6 immobed passes it through one and a fixed support rod 5 through the other.
- This is fixed to an actuator 7 mobi the servo by an electronic control system to compress a sample E.
- the piston 4 extends to a tip 8 whose free end face is in the form of a concave spherical cap 9.
- the support rod 5 also has a nozzle 10 terminated by a free end face in the form of a concave spherical cap 11.
- the support of the compression device 12 is placed without any prior adjustment on the concave spherical cap 11 by a surface in the form of convex spherical cap which therefore forms a ball joint with the spherical cap 11. It carries at its other end a bore 13 with a circular section in which there slides a piston end 14 of the compression device, of the same section and whose upper end is terminated by a convex spherical cap which partially fits into the concave spherical cap 9 so as to form another ball joint.
- the sample holder 12 is hollowed out according to a transverse excavation 16 in which the bore 13 passes through.
- Each of the anvils 17 and 18 is more precisely a short cylinder, one face of which rear lane 19 is supported on the bottom surface, also flat, of a blind hole 20 of the same section hollowed out at the end of the piston end 14 and in the sample holder 12 , and a flat front face 21 serves to support the sample E and to compress it between these two front faces 21 which are parallel; finally, a circular side surface 22 of the anvils 17 and 18 and fitted into the side wall of the blind holes 20.
- the heating device is composed of a thermal insulation shield 24 and two half-resistors 25 providing heating.
- the thermal insulation shield 24 makes it possible to confine the compression device in a heating zone composed of two half-resors 25, each connected to the two half-shells of the oven enclosure 1.
- the configuration adopted makes it possible to wear the compression device (piston 14, support 12, and anvils 17 and 18) at the same temperature as sample E, while the support rod 5 and the piston 4 remain at an almost invariable temperature.
- the heating device is provided with a thermocouple 27 allowing the regulation of the temperature, and a thermocouple 28 ensuring the measurement of the temperature on the sample E.
- the compression device allows the deformation of the sample to be measured during the total duration of a test. Its shape (transverse excavation 16 of the support 12 and form of the anvils 17 and 18) adapted to a contactless extensometry by means of a laser allows the measurement of the following quantities of the material tested at high temperature (Young's modulated, coefficient of expansion , elastic and plastic deformations); The measurement is made by a slot 26 made in the loop ther that 24.
- the compression device produced is able to solicit ceramic samples up to 2200 ° C under vacuum or under controlled atmosphere, and carbonaceous products up to 3000 ° C under controlled atmosphere.
- the loads that can be reached are 100,000 N at 1,500 ° C for example.
