due to the great variety of applications of magnesium alloys with superior mechanical properties, recent studies have been focused on the hot deformation behavior and microstructure of magnesium alloy castings. although there have been several recent investigations on the microstructure of wrought magnesium alloys after hot deformation, a limited number of studies have been conducted with regar...

Phenomenological approach to the description of deformation resistance behaviour of steel and its microstructure development under the service hot rolling condition is still the most common useful and powerful. Utilising different experimental equipment such as torsion plastometer [1-5], compression plastometer [6-9], or advanced laboratory mills [10, 11] as well as different deformation techni...

A previous constitutive modeling for single-phase steels is extended using the mixing law to predict behavior of hot deformation in dual phase ferritic-austenitic intercritical zone Fe-C-Mn-Si alloys. Mixing considers two phases instead one, so one formula was modified. The constant’s values used represents average same conditions austenitic and ferritic model. amount each determined as functio...

the aim of this study is to investigate the nucleation of new grains by necklacing mechanism during dynamic recrystallization (drx). the material used is 316 stainless steel. in order to modeling the deformation behavior during hot rolling, one-hit compression tests were performed at temperature range of 950-1100 °c with strain rates of 0.01-1s-1. the result shows that at the temperature of 100...

steel 2205 is one of the most famous duplex stainless steels. the microstructure of this steel composed of ferrite and austenite in similar amount. therefore, in order to improve mechanical properties through microstructure, thermo mechanical processes such as controlled hot rolling and forging should be applied. it is not possible to employ the usual heat treatment. it shows the importance of ...
