    • It is important to know how sheet metals behave under complicated loading conditions, since yielding and hardening of a metal are actually dependent upon the stress state and deformation history. An example is the Bauschinger effect, which is manifested as a loss of yield strength during reverse loading upon plastic prestraining. Quantitative analysis of the Bauschinger effect is required for better understanding of this problem. In this study, experiments carried out by subjecting sheet metals to uniaxial compression-tension tests show that the Bauschinger effect varies with the material properties and the magnitude of prestrain. On the basis of the experiments and the continuum theory of plasticity, parameters defining the Bauschinger effect are proposed, which interpret the combined effect of work hardening and work softening of a material during forward and reverse straining, and a model revealing the Bauschinger effect on the subsequent yield surface is finally presented

  • On the thermodynamics and kinetics of carbides in the aluminium-rich corner of the AlTiC phase diagram
  • 1991
  • Ingår i: Materials Science & Engineering. - 0921-5093 .- 1873-4936. ; 135:C, s. 119-123

    • Aluminium composites have a great potential because of their high strength-to-weight ratio. Carbides will in the future be powerful reinforcements. To be able to manufacture these it is of importance to know the thermodynamic properties and the kinetic limitations. The objective of this investigation is to study the equilibria between the carbides occurring in the AlTiC system as well as the initial precipitation and dissolution behaviour of these carbides. It can be shown that there is a change in stability between TiC and Al4C3, depending on both composition and temperature. To study the nucleation and precipitation behaviour of the carbides in liquid aluminium and aluminium alloys a set of alloys were melted and heated to an appropriate temperature in graphite crucibles. The effect of time and the effect of composition on the chemical reactions involving carbides have been investigated. A theoretical analysis of both the thermodynamics and kinetics was performed, giving a tentative explanation. © 1991.
