The microstructure evolution and strengthening mechanism of a γ′-strengthening superalloy prepared by induction-assisted laser solid forming

Journal of Alloys and Compounds, 2019
The microstructure evolution and strengthening mechanism of a γ′-strengthening superalloy prepared by induction-assisted laser solid forming (LSF) were clarified by an investigation of the LSFed IN-738LC alloy with different solution treatments (at 1070 °

Creep Strengthening Mechanisms

1982
In the choise of the materials for the most crytical high temening mechanisms in superalloys. Solid solution-, particle-, and dislocation-strengthening are considered in dislocation creep. σ∘ concept is discussed and σ∘ data of superalloys reported. Diffusional creep and grain boundary sliding are also examined.

Strengthening Mechanisms in Mg97Zn1Y2 Alloys

2015
We elucidate the strengthening mechanisms of Mg-Zn-Y alloys containing long-periodic stacking ordered (LPSO) structures, based on comprehensive electron microscopy investigations. Kinking of the LPSO structures is not only an important way to accommodate plastic deformation effectively, but also simultaneously strengthens the alloy as a result of ...

The Mechanism of Polyvinylamine Wet-strengthening

Trans. of the XIIIth Fund. Res. Symp. Cambridge, 2005, 2005
Regenerated cellulose films were laminated with polyvinylamine, PVAm, and the wet peel delamination forces were used to explore the mechanism by which PVAm increases the wet strength of paper. Conventional wet strength resins contain highly reactive chemical groups which can crosslink the resin and graft it to fibre surfaces.

THE STRENGTHENING MECHANISM OF FERROUS MARTENSITE

1963
Abstract : A model is proposed to account for the observed strengthening behavior of ferrous martensites. The model is based upon the inheritance of carbon rich regions by the martensite which were present in the austenite prior to transformation. These carbon rich regions strengthen the martensite in a manner analogous to the strengthening effect due ...

Strengthening mechanisms in aluminum alloys

2011
The substructure of pure aluminum and over-aged Al-4Cu has been varied by mechanical and thermal treatments. The nature of this substructure and its resistance to annealing has been studied, together with the effect of the substructure on tensile strength at ambient and elevated temperatures.
