Journal ArticleDOI
A critical review of powder-based additive manufacturing of ferrous alloys: Process parameters, microstructure and mechanical properties
Haniyeh Fayazfar,Mehrnaz Salarian,Allan Rogalsky,D. Sarker,Paola Russo,Vlad Paserin,Ehsan Toyserkani +6 more
TL;DR: In this article, different powder-based additive manufacturing processes deployed to ferrous alloys, their key process parameters, phase transformation and microstructure development during solidification, all of which impact on mechanical behavior.
Journal ArticleDOI
3-D finite element modeling of laser cladding by powder injection: effects of laser pulse shaping on the process
TL;DR: In this article, a 3D transient finite element model of laser cladding by powder injection is introduced to investigate the effects of laser pulse shaping on the process, where the interaction between powder and melt pool is assumed to be decoupled and as a result, the melt pool boundary is first obtained in the absence of powder spray.
Journal ArticleDOI
Cladding of WC–12 Co on low carbon steel using a pulsed Nd:YAG laser
TL;DR: In this article, a pulsed Nd:YAG laser was used to deposit multi-layer overlapped cladding on low carbon steel substrate using dynamic powder blowing technique, and the results showed that fully dense and crack free clad surfaces of WC-Co with an excellent metallurgical bonding and low dilution were deposited.
Journal ArticleDOI
A 3D dynamic numerical approach for temperature and thermal stress distributions in multilayer laser solid freeform fabrication process
TL;DR: In this article, a 3D transient numerical approach for modeling the multilayer laser solid free-form fabrication (LSFF) process is presented, where coupled thermal and stress domains are numerically obtained assuming a decoupled interaction between the laser beam and powder stream.
Journal ArticleDOI
3-Dimensional heat transfer modeling for laser powder-bed fusion additive manufacturing with volumetric heat sources based on varied thermal conductivity and absorptivity
Zhidong Zhang,Yuze Huang,Adhitan Rani Kasinathan,Shahriar Imani Shahabad,Usman Ali,Yahya Mahmoodkhani,Ehsan Toyserkani +6 more
TL;DR: In this paper, a 3D heat transfer finite element model for laser powder-bed fusion (LPBF) was developed for accurately predicting melt pool dimensions and surface features, which can be used to reduce the process/material development costs.
