In addition, internal pore ... -
Characterization of single- and multilayer cold-spray coating of Zn on AZ31B
Marzbanrad, Bahareh; Toyserkani, Ehsan; Jahed, Hamid (Elsevier, 2021-06-25)Zinc, a soft material with a low melting point and high corrosion resistance, was coated onto AZ31B Mg alloy using different cold spraying process parameters. The physical and mechanical properties of the resulting Zn/AZ31B ... -
Dendritic coarsening model for rapid solidification of Ni-superalloy via electrospark deposition
Enrique, Pablo D.; Jiao, Zhen; Zhou, Norman Y.; Toyserkani, Ehsan (Elsevier, 2018-08-01)Control of splat thickness in an electrospark deposition (ESD) process can be used to improve the mechanical properties of deposited Inconel 718. The lower cooling rates of thicker deposition splats obtained through higher ... -
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), ... -
Process Planning for Additive Manufacturing of Geometries with Variable Overhang Angles using a Robotic Laser Directed Energy Deposition system
Kaji, Farzaneh; Jinoop, Arackal Narayanan; Zimny, Mark; Frikel, German; Tam, Kyle; Toyserkani, Ehsan (Elsevier, 2022-01)In the present work, a novel Laser Directed Energy Deposition (LDED) process planning methodology is proposed to build a dome structure with variable overhang angles. Overhang structures with different overhang angles were ... -
Rapid prediction of real-time thermal characteristics, solidification parameters and microstructure in laser directed energy deposition (powder-fed additive manufacturing)
Huang, Yuze; Ansari, Mohammad; Asgari, Hamed; Farshidianfar, Mohammad Hossein; Sarker, Dyuti; Khamesee, Mir Behrad; Toyserkani, Ehsan (Elsevier, 2019-12)The localized thermal characteristics, solidification parameters and the corresponding microstructure depend highly on the process parameters in the laser powder-fed additive manufacturing (LPF-AM) process. However, ... -
