Influence of cold working on the development of interrupted decomposition of precipitation-hardening alloy of nickel-chromium-niobium system

An influence of small and moderate preliminary cold working on the completeness and kinetics of interrupted decomposition process development, on the position and extent of its time-temperature region in the presipitation hardening alloy of the N71Kh20B9 type has been analyzed by the construction of isothermic decomposition using the quantitative metallography method. General principles of formation of the time-temperature region are shown of the interrupted decomposition in the alloy, where in the process of decomposition of an oversaturated solid solution, besides interrupted, separation of an abundant phase, observed is also the total continuous and Widmanstaetten one
