Anisotropy in the quasi-static and cyclic behavior of ZK60 extrusion: Characterization and fatigue modeling
Pahlevanpour, Amirhossein H.; Karparvarfard, Seyyed M. H.; Shaha, Sugrib K.; Behravesh, Seyed Behzad; Adibnazari, Saeed; Jahed, Hamid (Elsevier, 2018-12-15)The quasi-static and strain-controlled fatigue characteristics of ZK60 extrusion have been investigated along three different directions: the extrusion direction (ED), the radial direction (RD), and 45° to the extrusion ... -
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 ...
