A critical evaluation of the microstructural gradient along the build direction in electron beam melted Ti-6Al-4V alloy [PDF]

, 2019
It is generally recognised that electron beam melted (EBM) Ti-6Al-4V alloys exhibit a microstructural gradient along the build direction, but there have been some inconsistent experimental observations and debate as to the origin and magnitude of this ...

Superplastic behaviour of Ti54M and Ti64 [PDF]

, 2020
Even though TIMETAL-54M (Ti-5Al-4V-0.6Mo-0.4Fe or Ti54M) has been commercially available for over 10 years, further study of its superplastic properties is still required in order to assess its applicability within the aerospace industry as a potential ...

Substrate Effect on the High Temperature Oxidation Behavior of a Pt-modified Aluminide Coating. Part II: Long-term Cyclic-oxidation Tests at 1,050 C [PDF]

, 2007
This second part of a two-part study is devoted to the effect of the substrate on the long-term, cyclic-oxidation behavior at 1,050 C of RT22 industrial coating deposited on three Ni-base superalloys (CMSX-4, SCB, and IN792).

Optimization of a Solution Treatment in the Al-Cu-Mg-Ag Alloy via a Microstructural Investigation

Metals, 2021
We investigated the effect of solution temperature (Tsol. = 440–530 °C) on the mechanical properties of the Al–3.4Cu–0.34Mg–0.3Mn–0.17Ag alloy, finding that the investigated Al alloy showed the highest mechanical strength of σUTS = ~329 MPa at a Tsol ...

Microstructure Evolution of Tin–Lead Solder [PDF]

IEEE Transactions on Components and Packaging Technologies, 2004
Microstructural length scales are relatively large in typical soldered connections. The microstructure which is continuously evolving is known to have a strong influence on damage initiation and propagation. In order to make accurate lifetime predictions by numerical simulations, it is therefore necessary to take the microstructural evolution into ...

Dynamic recrystallization mechanisms and twining evolution during hot deformation of Inconel 718 [PDF]

, 2016
The hot deformation behavior of an IN718 superalloy was studied by isothermal compression tests under the deformation temperature range of 950–1100 °C and strain rate range of 0.001–1 s-1 up to true strains of 0.05, 0.2, 0.4 and 0.7.

Microstructure and corrosion evolution of additively manufactured aluminium alloy AA7075 as a function of ageing [PDF]

, 2019
Additively manufactured high strength aluminium alloy AA7075 was prepared using selective laser melting. High strength aluminium alloys prepared by selective laser melting have not been widely studied to date. The evolution of microstructure and hardness,

High temperature oxidation and microstructural evolution of cold spray chromium coatings on Zircaloy-4 in steam environments

Journal of Nuclear Materials, 2019
Oxidation kinetics and microstructural evolution of cold sprayed Cr coatings on Zircaloy-4 at 1130–1310 °C in flowing steam at atmospheric pressure have been studied. The study is aimed at understanding of the response of Cr coated Zr-alloy under a steam
