Hot deformation map and its application of GH4706 alloy

查看参考文献16篇

文摘 The hot deformation behaviors of GH4706 alloy were investigated using compression tests in a deformation temperature range from 900°C to 1200°C with a strain rate range of 0.001-1 s~(-1). Hot processing maps were developed on the basis of the dynamic material model and compression data. A three-dimensional distribution of power dissipation parameter (η) with strain rate and temperature reveals thatηdecreases in sensitivity with an increase in strain rate and a decrease in temperature. Microstructure studies show that the grain size of GH4706 alloy increases whenηis larger than 0.32, and the microstructure exhibits local deformation whenηis smaller than 0.23. The hot processing map at the strain of 0.7 exposes a domain peak atη=0.32 for the temperature between 940°C and 970°C with the strain rate from 0.015 s~(-1) to 0.003 s~(-1), and these are the optimum parameters for hot working.
