METHOD FOR MEASURING THE MECHANICAL CHARACTERISTIC OF MATERIAL B CONDITIONS OF HYDROSTATIC PRESSURE (VERSIONS)

摘要

1. A method of measuring mechanical properties of the material under hydrostatic pressure, comprising placing sample material surrounded by superplastic metal in a matrix device providing a hydrostatic pressure conditions on the sample, a load is applied to the sample, characterized in that the load carried by two punches, wherein an external die sets hydrostatic pressure on the sample of the material when it is exposed to high ductility metal, and an inner punch provides load directly to materiala.2 sample. A method according to claim 1, characterized in that the superplastic metal is lead or alyuminiy.3. A method according to claim 1, characterized in further comprising heating or cooling device with the sample matrix in the temperature range from 100 K to a melting temperature plastic materiala.4. A method for determining the material mechanical properties in conditions of hydrostatic pressure, comprising placing sample material surrounded by superplastic metal in a matrix device providing a hydrostatic pressure conditions on the sample, a load is applied to the sample, characterized in that the load on the sample material is carried out by one punch, which sets the hydrostatic pressure on the sample when it is exposed to high ductility metal and simultaneously provides the load directly on the sample ma Methods and material, wherein the device has a channel matrix, the cross section of which determine the hydrostatic pressure acting on the sample materiala.5. A method according to claim 4, characterized in that the superplastic metal ispol'uet
