in the present study, the microstructural changes of a nickel based superalloy nimonic80a during a non-isothermal deformation were studied. therefore, microstructure evolutionduring hot side pressing test was predicted with combined methods of finite element analysis andprocessing map of the material. the predicted results were validated through experimentalmicrostructural studies. the results ...

abstract the character element, as the main construction fund of every story, plays a significant role in the procedure of processing the plot, shaping the events and moving forward in any narrative text. the book of “al-avasef” written by gibran contains some short stories in which the author considers and cares about character element and methods of its processing. in the present study, with ...

The purpose of introducing ultrasonic vibrations in the tube hydroforming process is to create more formability by obtaining a lower corner radius, improve thickness distribution of the wall and provide good tribological conditions at the tube and the die interface. Vibrations imposed on the die create alternating gaps which improve the formability in the tube hydroforming process in the presen...
