The temperatures of phase transformations and nature of phases-products of interaction were determined during conventional and solid HDDR. It was found the conditions of complete disproportionation of the alloy: holding for (2-5) h at p=(0.4-0.5) МPа and 913 К. The HDDR leads to the formation of homogeneous fine grains structure in the KC37 alloy with crystallites size of <1mcm. The conditions of texture formation in the KC37 alloy by means of modified HDDR treatment at (873-1173) К were established in the first time. The crystalline texture coincides with magnetic one. The texture degree and phase composition of the alloy are depended on treatment temperature. Product Description popup.authors popup.nrat_date 2020-04-02 Close
