A model for coherency strengthening of large precipitates

Scripta Materialia, 2014
In precipitation strengthening, the lattice misfit between precipitate and matrix produces a strain field around precipitates, which impedes dislocation movement. In this paper, a strengthening model is presented, which delivers the stress increment associated with the strain field around large homogeneous spherical precipitates.

Origin of strengthening on precipitation: Ordered particles

Acta Metallurgica, 1957
Abstract An analysis is given to show that the presence of order in precipitate particles can give rise to considerable strengthening even in the absence of strains. Some of the implications of this are given and systems which might owe their strength to this mechanism are discussed.

Modeling quenching of precipitation strengthened alloys

Products of precipitation strengthened alloys characteristically lose their ability to develop peak properties as the rate of the quench from the solution temperature is reduced. An analytical model was developed which improved on a previous model to predict mechanical properties of such materials from time-temperature-property, TTP, C-curves and a ...

Coherent Precipitate Strengthening Mechanisms in MgO

1975
MgO containing magnesia ferrite particles is a model system for the study of the interaction between dislocations and second phase particles in ceramic materials. Therefore, several investigations have been performed on two-phase MgO under this aspect [1–7]. Magnesia ferrite crystalizes as inverse spinel with disorder [18].

Precipitation strengthening in multi-particle systems

2014
Abstract The present thesis describes the main aspects of a physical model for precipitation strengthening in crystalline materials. For evaluation of the yield strength increase, a set of equations is derived based on the interaction between dislocations and precipitates. Different shearing and non-shearing mechanisms are discussed critically based on
