Temperature dependence of resistance to micro- and macrodeformation in precipitation-hardening Co-Ni-Ti and Co-Ni-Ti-Al alloys. II

The temperature dependence of mechanical properties (T) in the region of micro- and macroformations ( - 10^–6-10^–3) of the Co-Ni-Ti, and Co-Ni-Ti-Al alloys was studied in various structural states. It was shown that precipitation of Co³Ti phase in the alloy being investigated does not determine the anomalous temperature dependence (T) similar to that observed in various alloys with precipitation of Ni₃Al phase. Experimental data obtained indicated that temperature dependence of macroscopic yield point is determined by the dependence of the resistance to the onset of plastic flow on temperature.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 9, pp. 52–57, September, 1972.
