Journal ArticleDOI
Transmission electron microscopy investigation of separated nucleation and in-situ nucleation in AA7050 aluminium alloy
Tsai-Fu Chung,Yo-Lun Yang,Bo-Ming Huang,Zhusheng Shi,Jianguo Lin,Takahito Ohmura,Jer-Ren Yang +6 more
TL;DR: In this paper, high-resolution transmission electron microscopy (HRTEM) with nanometer-scaled energy-dispersive X-ray (EDX) was employed to investigate the transformation mechanisms of the GP zone → η′ → ∞ precipitation sequence of AA7050, an Al-Zn-Mg-Cu alloy.
Journal ArticleDOI
An atomic scale structural investigation of nanometre-sized η precipitates in the 7050 aluminium alloy
Tsai-Fu Chung,Yo-Lun Yang,Makoto Shiojiri,Chien-Nan Hsiao,Wei-Chih Li,Cheng-Si Tsao,Zhusheng Shi,Jianguo Lin,Jer-Ren Yang +8 more
TL;DR: Using high-angle-annular-dark-field (HAADF) scanning-transmission-electron microscopy (STEM) images taken along the zone axes of [10 1 ¯ 0]η, [1 2 ¯ 10] η, and [0001] Δη illustrated the projected atomic-scale configurations of η-MgZn2 crystal as mentioned in this paper.
Journal ArticleDOI
A unified constitutive model for asymmetric tension and compression creep-ageing behaviour of naturally aged Al-Cu-Li alloy
Yong Li,Zhusheng Shi,Jianguo Lin,Yo-Lun Yang,Qi Rong,Bo-Ming Huang,Tsai-Fu Chung,Cheng-Si Tsao,Jer-Ren Yang,Daniel S. Balint +9 more
TL;DR: In this paper, a set of unified constitutive equations is presented that predict the asymmetric tension and compression creep behavior and recently observed double primary creep of pre-stretched/naturally aged aluminium-cooper-lithium alloy AA2050-T34.
Journal ArticleDOI
Experimental investigation of tension and compression creep-ageing behaviour of AA2050 with different initial tempers
TL;DR: In this article, a double primary creep feature has been observed in both as-quenched and pre-stretched/natural-aged alloys, in which an intermediate inverse creep stage with an increasing creep strain rate locates between the initial primary+transient steady-state creep stages and the second primary+second steady state creep stages.
Journal ArticleDOI
In-situ transmission electron microscopy investigation of the deformation behavior of spinodal nanostructured δ-ferrite in a duplex stainless steel
Yi-Chieh Hsieh,Ling Zhang,Tsai-Fu Chung,Yu-Ting Tsai,Jer-Ren Yang,Takahito Ohmura,Takuya Suzuki +6 more
TL;DR: In-situ compression tests in a transmission electron microscope were carried out to investigate the deformation behavior of δ-ferrite nanopillars of a duplex stainless steel as mentioned in this paper.
