Popis: The products of thermobaric treatment of the metastable Re0.50Rh0.50 nanocrystalline phase (a= 2.733(2) A, c = 4.364(4) A, space group P63/mmc, CSR ∼5 nm) in a high-pressure chamber were studied. Storage of the phase at 2000°C and 1.5 GPa for 3 min led to the formation of a fused particle (O∼1 mm). The initial composition did not change, but the coherent scattering region (CSR) increased to 52 nm. An increase to 4 GPa in pressure also did not lead to a decomposition of the metastable Re0.50Rh0.50 phase, the unit cell parameters remained the same, and the size of the CSR increased by a factor of four.
