at 1030~ 1300 ℃ and the effect of temperature on max stress and reduction of area of alloys have been studied by using Thermomac-master-Z hot simulator
TEM and SEM
and the effect factors on dynamic recrystallization of alloys were analyzed. Results showed that with increasing temperature compensating factor Z
the grain size of dynamic-crystallizing of alloy G3
G3-Z and 825 decreased
and the available temperature range for hot-working was 1100~1240 ℃ for alloy G3
1130~1220 ℃ for alloy G3-Z and 1050~1240 ℃ for alloy 825.
