Finite Element Simulation And Experiment Research On Hot Rolling Of AZ31Magnesium Alloy Rod

Magnesium alloy known as the "21st century green engineering material", has beengradually used in aerospace, automotive electronics, armament and other industries, has abroad application prospect. In this paper， through the study of AZ31magnesium alloyplasticity，looking for high-strength magnesium alloy rod rolling process suitable route.Hot-rolled magnesium alloy can be overcome at room temperature plastic deformationpoor shortcomings, rolling magnesium alloy also make better organizational structure andmaterial properties, but to develop and improve the production process route, but alsorequires a longer theoretical analysis and test cycle. Rolling through the traditional theory ofexperience, roughly the production process design, we design two different rolling systems,comparative advantages and disadvantages of the two programs, through the rolling processis simulated on the field distribution, the metal flow patterns and rolling force changes wereanalyzed to determine the better option, and the analysis and comparison of differenttemperatures to determine the main parameters of rolling and eventually develop a moreappropriate process.After a three-roll mill Y-developed process route is completed by rolling test, completeAZ31magnesium alloy bar from rolling to Ф85Ф95, and to get a better surface quality of therolled bar, air-cooled, after rolling bars slices on XJP-6A metallographic microscopemicrostructure results show after rolling bar has better mechanical properties.By studying this topic，magnesium alloy and rolling plastic deformation theory has morein-depth understanding of the use of DEFORM-3D to simulate the hot rolling process,analyzes the development of an appropriate process route through simulation, high-strengthmagnesium alloy rod The actual production of material significance.
