Jamei 4 School of Metallurgy and Materials Engineering, College of Engineering, University of Tehran, P.O. Box, Tehran, IranMotivating the unmotivated: how can health behavior be ...Jun 16, 2015 · According to this perspective, behavior is driven by two processes: conscious consideration of the pros and cons or expectancies of the value of engaging in the behavior relative to potential costs of doing so, and non-conscious processes that are spontaneous, impulsive, and occur with little deliberative thought (e.g., Strack and Deutsch, 2004; Hagger and Chatzisarantis, 2014, 2015 .Work-hardening behaviour of Mg single crystals oriented ...Work-hardening behaviour of Mg single crystals oriented for basal slip was studied by means of tensile tests carried out at 4, 78 and 295 K. The crystals show critical resolved shear stress values (CRSS) for a {0001} basal slip system in the range 1–1.5 MPa. The samples exhibit two-stage work hardening characteristics consisting of a long easy glide stage and a stage of rapid hardening ...

  • Rate sensitivity and work-hardening behavior of an ...

    The tensile results indicated a gradually changed strain hardening behavior due to the increase of impurity atoms, while the results of strain rate jump test suggested a reduced value for SRS with increasing either the impurity content or the plastic strain.What is strain softening and strain hardening? - QuoraNov 14, 2017 · The dislocation interaction is repulsive in nature. As the dislocation density increases the further deformation of the material become difficult, this is called Work Hardening or Strain Hardening. Work hardening may be desirable or undesirable depending on the context.Work Hardening Behaviour of Heat-Treatable Al-Mg-Si-AlloysThe work hardening of alloys hardened by precipitate heat treatments depends on the distribution of the precipitate sizes and the solute level left in the metal matrix. A mean field theory for precipitation is first applied for the ageing and subsequently it is coupled to a work hardening model to study the stress-strain responses of age hardened conditions of AA6xxx alloys.
