Investigation of microstructure and mechanical properties of W-Y and W-Y2O3 materials fabricated by powder metallurgy method

W-2Y, W-1Y(2)O(3) and W-2Y(2)O(3) materials have been fabricated using two different powder metallurgy methods. While W-2Y and W-1Y(2)O(3) have been fabricated using mechanical alloying and hot isostatic pressing (Hipping), W-2Y(2)O(3) has been fabricated ...

Factors affecting the strength of P{011}〈566〉-texture after annealing of a cold-rolled Al–Mn–Fe–Si alloy

Ke Huang

Elongated coarse P{011}-oriented grains are frequently observed after annealing of cold-rolled Al–Mn alloys with a highly supersaturated solid solution level. In this study, important factors affecting the strength of the P-texture component after ann ...

Effect of heterogeneously distributed pre-existing dispersoids on the recrystallization behavior of a cold-rolled Al–Mn–Fe–Si alloy

Ke Huang

It is well known that strong concurrent precipitation, mainly located along grain/subgrain boundaries, results in a coarse and elongated grain structure, and unusual sharp P {011} and/or M {113} texture components during annealing of supersatur ...

Early cluster formation during rapid cooling of an Al-Cu-Mg alloy: In situ small-angle X-ray scattering

Jean-Marie Drezet, Helena Van Swygenhoven, Patrick Schloth

The formation of Cu-Mg clusters in an Al-Cu-Mg aluminum alloy is observed by small-angle X-ray scattering during cooling. Cooling rates are choosen to mimic the different conditions obtained at the surface and in the center of large forgings. Clusters of 0 ...

Two-stage annealing of a cold-rolled Al–Mn–Fe–Si alloy with different microchemistry states

Ke Huang

The influence of microchemistry on the softening behaviour of two cold-rolled Al–Mn–Fe–Si alloys with different initial amounts of Mn (0.4 and 1.0 wt%) is studied. In addition to their as-cast conditions, the supersaturated Al–Mn–Fe-Si alloys were appropri ...

The effect of heating rate on the softening behaviour of a deformed Al–Mn alloy with strong and weak concurrent precipitation

Ke Huang

The interaction between recrystallization and concurrent precipitation is strongly dependent on the heating rate during annealing. In this study, the effects of heating rate on the grain structure, recrystallization texture and resulting mechanical propert ...

Quench-Induced Stresses in AA2618 Forgings for Impellers: A Multiphysics and Multiscale Problem

Jean-Marie Drezet, Nicolas Paul Henry Chobaut, Gilles Michel, Denis Carron

In the fabrication of heat-treatable aluminum parts such as AA2618 compressor impellers for turbochargers, solutionizing and quenching are key steps to obtain the required mechanical characteristics. Fast quenching is necessary to avoid coarse precipitatio ...

Evolution in microstructure and properties during non-isothermal annealing of a cold-rolled Al-Mn-Fe-Si alloy with different microchemistry states

Ke Huang

The softening behaviour during non-isothermal annealing of a cold-rolled Al–Mn–Fe–Si model alloy was studied as a function of the state of microchemistry, in terms of the solute level of Mn, size and spatial distribution of the Mn-bearing dispersoids, as w ...

Microstructural influence on the scatter in the fatigue life of steel reinforcement bars

Alain Nussbaumer, Marina Rocha Pinto Portela Nunes

Fatigue damage accumulation and failure of steel reinforcement bars (rebars) is a stochastic process. Scatter can be influenced by the sensitivity of the short crack growth to the microstructural features, especially near the fatigue limit. This work inves ...

Measurements and modelling of residual stresses during quenching of thick heat treatable aluminium components in relation to their precipitation state

Nicolas Paul Henry Chobaut

In the fabrication of heat treatable aluminium parts, solutionising and quenching are key steps in order to obtain the required mechanical characteristics. Fast quenching is necessary to avoid coarse precipitation as this one reduces the mechanical propert ...
