High Temperature Formability Prediction of Dual Phase Brass Using Phenomenological and Physical Constitutive Models

Processing Map Development through Elaborating Phenomenological and Physical Constitutive Based Models

“…The presence of new fine recrystallized alpha grains can be clearly recognized in the corresponding microstructures ( Figure 3). [29,30] It is well understood that for a given strain, the flow stress and strain rate can be related as follows: [31] The second category of flow curves at higher deformation temperatures (973 and 1 073 K) also exhibits a peak stress down to a steady state flow.…”

“…The detailed explanation about the occurrence of the restoration phenomenon can be found in previous studies. [29,30] It is well understood that for a given strain, the flow stress and strain rate can be related as follows: [31]…”

“…[29] Then the extracted models will be employed to develop the power efficiency and instability maps. [29] Then the extracted models will be employed to develop the power efficiency and instability maps.…”

“…In the following, two most renowned constitutive equations are used to predict the flow stress behavior and their prediction capability is estimated through statistical parameters mentioned in previous reports. [29] Then the extracted models will be employed to develop the power efficiency and instability maps. The strain compensated Arrhenius-type equation has been widely employed to describe the relationship between the strain rate, flow stress, and temperature, in particular at higher temperatures.…”

Rationalization of duplex brass hot deformation behavior: The role of microstructural components

“…Padmavardhani and Parsad [16,17], investigated the hot deformation behavior of the α and α-β brass using processing maps. In this respect, the authors [18] and Xiao et al [19] developed a constitutive model to describe the hot deformation behavior of the duplex brass.…”
