The General Electric Company's (GE's) iconic Appliances division enjoyed a significant role in the company throughout the 20th century, representing one of the most recognized engines of the GE brand. By the 21st century, however, GE had changed its

Preliminary indications concerning the applicability of X2095-type alloys for warm temperature applications (125--200 C) are encouraging. The strength capability is clearly demonstrated. Before commitments are made to this alloy system for elevated t

A dramatic increase in strength and significant loss in ductility was observed for material that was compressed 30%, exposed to 538 °C and tensile tested at room temperature (compared to as-compressed material). The effect was less dramatic at lower

—The low cycle fatigue (LCF) behavior of two aluminum-lithium alloys was investigated. Efforts were aimed at understanding the effects of microstructure on the cyclic stress-strain behavior and methods by which different microstructures accommodate

Annealing alloys that contain the critical amount of retained strain usually results in a large final grain size, because the recrystallization reaction is nucleation limited. Subsequent growth of these nuclei through strained material rapidly produc

Although aluminum-lithium alloys showed initial promise for aerospace applications, implementation has not proceeded swiftly. In this study, efforts were made to design and develop microstructures with good fracture and fatigue crack propagation resi

Deformation behaviour is predicted by combining slip intensity calculations for shearable precipitates (δ′) with critical particle size (for dislocation shearing-to-looping transition) estimates for strong precipitates (T1, S′). The deformation

The influences of microstructure and deformation mode on inert environment intrinsic fatigue crack propagation were investigated for Al-Li-Cu-Mg alloys AA2090, AA8090, and X2095 compared to AA2024. The amount of coherent shearable δ (Al3Li) precipit

The microstructural features that determine fracture, toughness, and the mathematical models that relate those features to the plane strain fracture toughness, K IC , for aluminium alloys are described. Particular attention is paid to the new class o

The short-transverse fracture toughness of AA8090 is dramatically improved by double aging treatments, which produce a transition from coarse planar slip to homogeneous deformation. Although the fracture mode remains intergranular, stress concentrati
