Crushing, of samples

An alternative is cryogenic crushing of samples as described in ISO method 14507. 

The transformation process of p phase can be accelerated under ciystals deformation and pressure [140], For example the partial transformation of P to y can be caused at room temperature through crushing of sample in hydraulic press. It accelerates probably nuclei formation of this phase as the result of crystals shearing. From the other side when the powdered sample of p phase is exposed to the hydrostatic pressure of 900 MPa no transformation is observed, becanse y has lower...
