THE EFFECT OF SEVERE PLASTIC DEFORMATION ON THE MICROSTRUCTURE AND MECHANICAL PROPERTIES OF AS-CAST AZ31
The evolution of microstructure and mechanical properties of a magnesium cast alloy (AZ31) processed by equal channel angular pressing (ECAP) at two different temperatures were investigated. The as-cast alloy with an average grain size of 360 was significantly refined to about 5 after four ECAP passes at 543 K. Grain refinement was achieved through dynamic recrystallization (DRX) du...
متن کاملMicrostructure and High Temperature Deformation Behavior of Cast 310S Alloy
High temperature deformation behavior of cast 310S stainless steel has been investigated in this study by performing tensile and compression tests at temperatures from 900 to 1200C. Rectangular ingots of which the dimensions were 350×350×100 in millimeter were cast using vacuum induction melting. Phase equilibrium was calculated using the FactSage®, thermodynamic software and database. Thermal ...

Article history: Received 2 January 2015 Received in revised form 22 October 2015 Accepted 23 October 2015 Available online 27 October 2015 The hot deformation behaviour of Inconel alloy IN718 was studied in the temperature range of 950–1100 °C and at strain rates of 0.01 and 1 s with a view to understand the microstructural evolution as a function of strain rate and temperature. For this purpo...
متن کاملMicrostructure and micro-texture evolution during large strain deformation of an aluminium–copper–lithium alloy AA 2195
Article history: Received 12 July 2014 Accepted 11 September 2014 Available online 20 September 2014 A single hit, hot isothermal plane strain compression (PSC) test was used to understand the microstructural evolution during large strain deformation of aluminium–copper–lithium alloy AA 2195. Hot isothermal PSC tests were conducted in the temperature range of 300–450 C and at strain rates of 0....
متن کاملThe effect of twinning on texture evolution during ECAP processing of an AM30 magnesium alloy
An AM30 magnesium alloy was processed through ECAP method at 200 °C. Optical and transmission electron microscopy as well as electron back scattered diffraction (EBSD) technique were employed to characterize the deformed microstructure. A partially recrystallized microstructure including ultrafine/nano structures was obtained. The area fraction of 49% was measured for the recrystallized regions...
