Özet:

 

Changes in the grain sizes and flow stresses of AA2014 and AA6063  aluminum alloys subjected to compression tests at high temperatures in  various constant compression head speeds were investigated.  When  assessing the test results, constant strain rates were considered  instead of compression head speeds of the uniaxial compression testing  system after making the necessary mathematical transformation.   Specimens used in the test were prepared in cylindrical form and  deformed until 0.7 true strain.  As a result of compression tests,  true stress-true strain curves were obtained.  Test specimens were  quenched as soon as the tests ended.  The microstructures that  occurred after various hot deformations, which materials better  mechanical properties were studied with respect to  experimental work.  Data dealing with mechanical and microstuctural  properties under isothermal forging conditions were obtained for  industrial applications.
