A polycrystalline hot working ingot metallurgy processing route for γ/γ′ Co–Al–W superalloys has been developed. Based on Co–7Al–7W (at%), substitutions of Mo, V, Ti, Ta, Ni, Si, Fe and Cr were examined. The γ′ solvus was found to follow the same trends as those exhibited by alloys with higher fractions considered other investigators. Excessive additions lead discontinuous coarsening eventually, loss phase from microstructures observed. Ni examined, some success, restore raise temperature....
The lattice misfit and diffraction elastic constants in hot rolled polycrystalline Co–7Al–5W–2Ta Co–6Al–6W–2Ti (at.%) are measured using neutron synchrotron X-ray diffraction. the two alloys was found to be +0.67 +0.59%, at HRPD. increase with temperature, as Ni superalloys. This implies that amount of coherency strengthening increases temperature. show γ′ phase is less stiff than γ matrix all orientations, which means load shedding will occur phase.
Ultrabright x-rays capture the sequence of material damage accumulation during high strain rate catastrophic failure.
A steel with nominal composition Fe-28Mn-8Al-1.0C in mass percent was hot rolled at two temperatures, 1100 °C and 850 subsequently aged 550 for 24 h. The lower temperature rolling resulted a yield strength increment of 299 MPa while still retaining an elongation to failure 26%. large improvement attributed increase residual dislocation density which retained even after the ageing heat treatment. homogeneous precipitation κ-carbides both samples also showed that high did not adversely affect...
An extended phase field model of dislocations in Ni-base superalloys is presented. It incorporates the recently developed effective γ-surfaces for both matrix and precipitate phases, obtained from atomistic simulations. These novel feature extrinsic stacking faults as additional local minima. Thus, they offer an increased number available dislocation dissociation pathways within system. The new has been used to simulate a variety mechanisms γ′ shearing proposed literature. A critical...
A SiC reinforced Ti‐5Al‐5Mo‐5V‐3Cr matrix metal composite is developed. Monolithic blocks of alloy are hot rolled via pack rolling to produce foils for MMC panel fabrication. These consolidated using isostatic pressing and solution treated aged optimum strength. The panels exhibited a strength 2 GPa in tension 3.5 compression, compared the aerospace steel 300M, which has tensile 1.69 GPa. fatigue performance material exceeded that MMCs developed Ti‐21S or Ti‐6Al‐4V matrices. Finally,...
