    • Bimodal grain microstructure development during hot compression of a cast-homogenized Mg-Zn-Zr alloy 

      Hadadzadeh, Amir; Mokdad, Fatma; Shalchi Amirkhiz, Babak; Wells, Mary; Williams, Bruce W.; Chen, Daolun L. (Elsevier, 2018-05-02)
      Hot deformation of a cast-homogenized ZK60 alloy was studied by compression at a temperature of 450 °C and a strain rate of 0.001 s−1 to investigate microstructural evolution. The deformed microstructure was characterized ...
    • Effect of forging on the low cycle fatigue behavior of cast AZ31B Alloy 

      Toscano, Dwayne; Shaha, Sugrib K.; Behravesh, Seyed Behzad; Jahed, Hamid; Williams, Bruce W. (Elsevier, 2017-08-26)
      The effect of forging on the low cycle fatigue (LCF) behavior of cast AZ31B was investigated. The forging process was conducted at a temperature of 450°C and speed of 390mm/min. Fully reversed (Rε=-1) strain controlled ...
    • Fatigue characteristics and modeling of cast and cast-forged ZK60 magnesium alloy 

      Karparvarfard, S. M. H.; Shaha, Sugrib K.; Behravesh, Seyed Behzad; Jahed, Hamid; Williams, Bruce W. (Elsevier, 2019-01-01)
      The fatigue behavior of as-cast and cast-forged ZK60 magnesium alloy was investigated via fully-reversed strain controlled fatigue tests at different strain amplitudes. Microstructure analysis, texture measurement, and SEM ...
    • Low-cycle fatigue characterization and texture induced ratcheting behaviour of forged AZ80 Mg alloys 

      Gryguc, Andrew; Behravesh, Seyed Behzad; Shaha, Sugrib K.; Jahed, Hamid; Wells, Mary; Williams, Bruce W.; Su, Xuming (Elsevier, 2018-11-01)
      Stress-controlled uniaxial “push-pull” fatigue testing was conducted on as-received (cast and extruded) and closed-die cast-forged and extruded-forged AZ80 Mg alloy. The as-cast material possessed random texture and somewhat ...
    • Microstructure, texture and mechanical behavior characterization of hot forged cast ZK60 magnesium alloy 

      Karparvarfard, S.M.H.; Shaha, Sugrib K.; Behravesh, Seyed Behzad; Jahed, Hamid; Williams, Bruce W. (Elsevier, 2017-04-14)
      Uniaxial tension and compression tests were conducted to investigate the quasi-static performance of ZK60 Mg alloy in cast, followed by forging at optimum temperature of 450°C and a ram speed of 39mmmin-1. Microstructure ...
    • Monotonic and cyclic behaviour of cast and cast-forged AZ80 Mg 

      Gryguc, Andrew; Shaha, Sugrib K.; Behravesh, Seyed Behzad; Jahed, Hamid; Wells, Mary; Williams, Bruce W.; Su, X. (Elsevier, 2017-11)
      Tensile and strain-controlled fatigue tests were performed to investigate the influence of forging on the performance of cast AZ80 magnesium alloy. The obtained microstructural analysis showed that the as-cast AZ80 magnesium ...
    • A Study of the Axial Crush Response of Hydroformed Aluminum Alloy Tubes 

      Williams, Bruce W. (University of Waterloo, 2007-12-03)
      There exists considerable motivation to reduce vehicle weight through the adoption of lightweight materials, such as aluminum alloys, while maintaining energy absorption and component integrity under crash conditions. To ...
