TL;DR: In this article, the authors measured the ultimate tensile strength of a unidirectional glass-matrix composite and compared with predictions, using a refined solution of the stress field generated by an axisymmetric damage model, which incorporated the effect of stress concentration in the fiber caused by the presence of a matrix crack both before and after deflection at the fiber/matrix interface.

TL;DR: In this article, the application of the ring test to assess die-workpiece interface friction during forging of a flow softening material was investigated, and the calibration curves were generated by conducting finite element method (FEM) simulations of ring forging with different friction factors.

TL;DR: A powder metallurgy route based on hot isostatic pressing (HIP) of tape-cast monotapes was used for the direct fabrication of dense thin sheets (250-300μm thick) of gamma titanium aluminide (γ-TiAl) as discussed by the authors.

TL;DR: In this paper, the effect of density anisotropy on the flow behavior of partially consolidated powder compacts of an alpha-two titanium aluminide alloy (Ti-24A1-11Nb) was established by conducting hot compression tests on samples made by hot die pressing or hot isostatic pressing (hipping).
