Effect of alloy composition on hot deformation behavior of some Al-Mg-Si alloys
ODOH, DANIEL OGHENEKEWHE; Mahmoodkhani, Yahya; Wells, Mary (Elsevier, 2018-03-01)The hot flow stress behavior of three Al-Mg-Si alloys was determined by performing hot deformation compression tests on a Gleeble 3500 thermomechanical simulator over the temperature range 400 °C–550 °C and at strain rates ... -
Mathematical Modelling of the Material Flow and Microstructural Evolution During the Extrusion of AA3003 Aluminum Alloy
Mahmoodkhani, Yahya (University of Waterloo, 2013-09-25)A comprehensive mathematical model of the hot extrusion process for aluminum alloys has been developed and validated. The model is capable of predicting the material flow behaviour and microstructure evolution that occurs ... -
On the measurement of relative powder-bed compaction density in powder-bed additive manufacturing processes
Ali, Usman; Mahmoodkhani, Yahya; Imani Shahabad, Shahriar; Esmaeilizadeh, Reza; Liravi, Farzad; Sheydaeian, Esmat; Huang, Ke Yin; Marzbanrad, Ehsan; Vlasea, Mihaela; Toyserkani, Ehsan (Elsevier, 2018-10-05)Experimental studies in the literature have identified the powder-bed compaction density as an important parameter, governing the quality of additively manufactured parts. For example, in laser powder-bed fusion (LPBF), ...
