Compression test at low temperature is 130-150 K range and the conditions set out in the technical execution of the tests carried out at low temperatures. As observed with MS do not behave traction to mechanical stress as compact material. The pore structure of the MS presence influence the mechanical behavior of which have been found in the case of mechanical compression test at room temperature. EXPERIMENTAL DATA The test is to compression at lower temperatures, as for the environment, the compressive load applied to the first appearance of cracking. The test piece subjected to compression is cylindrical and of the same size as that subjected to compression at ambient temperatures. Appears in this case during the compression test specimen shortening and bulging. The cooling medium was the same for all three materials.
