英文摘要The flow stress-strain behavior of GH761 alloy was investigated via hot compression testing. The peak stress sigma(p), starting steady-state stress sigma s, and corresponding strain epsilon(p), epsilon(s) decrease with decreasing strain rate (epsilon) over dot constant temperature. At constant strain rate, sigma(p), sigma(s), and epsilon(s) drop with rising temperature, but epsilon(p) does not change obviously. On the basis of reducing original grain size, lowering deformed temperature and enhancing strain rate can well refine structure. The microstructure will be most homogenous and finest when the strain reaches the level that DRX is finished exactly. Further increasing the strain will promote the grain growth. The hot deformation constitutive equation obtained is as follows: (epsilon) over dot = 6.5 x 10(6)sigma(4.86)(p)exp(-461 X 10(3)/RT).
