Effect of coating weight on fiber laser welding of Galvanneal-coated 22MnB5 press hardening steel
Razmpoosh, Mohammad Hadi; Macwan, Andrew; Biro, Elliot; Zhou, Y. Norman (Elsevier, 2018-03-15)Tensile strengths of up to 1.5 GPa and fracture elongation of 8% in press-hardening steel (PHS) opened up a great opportunity to improve the crash performance of vehicles. However, due to the increased susceptibility to ... -
Investigation of Liquid-Metal-Embrittlement Crack-path: Role of Grain Boundaries and Responsible Mechanism
Razmpoosh, Mohammad Hadi (University of Waterloo, 2020-07-24)Liquid metal embrittlement (LME) has been reported in many structural materials, including steel, aluminum, nickel during hot working processes e.g. welding, brazing, heattreatment, leading to abrupt failure. In many of ... -
Liquid metal embrittlement in laser lap joining of TWIP and medium-manganese TRIP steel: The role of stress and grain boundaries
Razmpoosh, Mohammad Hadi; Biro, Elliot; Chen, Daolun L.; Goodwin, Frank; Zhou, Yang-Tao (Elsevier, 2018-11-01)High-Manganese austenite-containing steels with superior combination of strength and ductility have shown potential for enhancement of passenger safety and body-in-white (BIW) weight reduction. Even though Zn-coated ... -
Role of heat balance on the microstructure evolution of cold spray coated AZ31B with AA7075
Marzbanrad, Bahareh; Razmpoosh, Mohammad Hadi; Toyserkani, Ehsan; Jahed, Hamid (Elsevier, 2021-07)A promising solid-state coating mechanism based on the cold spray technique provides highly advantageous conditions on thermal-sensitive magnesium alloys. To study the effect of heat balance in cold spray coating on ...
