| Popis: | The temperatures ductility of the polycrystalline Ni 2.19 Fe 0.04 Mn 0.77 Ga alloy was investigated. The analysis of the temperature dependence of the specific magnetization shows that temperatures of the martensitic and magnetic phase transformations have the following values: M F =325 K, A S =343 K, T C =365 K. The differential scanning calorimetry shows that in the temperature range of 930 to 1070 K in the alloy the phase transition of the ordered L2 1 phase to disordered B2 phase is observed. The stress-strain curves of cylindrical samples of alloy at temperatures of 773 K, 873 K and 973 K were constructed. |
