Microstructural Characterization and Mechanical Properties of Friction-Welded IN718 and SS410 Dissimilar JointSpringer Science and Business Media LLC - Tập 7 - Trang 277-287 - 2018
P. Anitha, M. C. Majumder, V. Saravanan, S. Rajakumar
Continuous drive friction welding studies on IN718 and SS410 dissimilar combination have been investigated. The influence of friction-welded parameters on microstructure and mechanical properties was dealt in detail. Six different joints were fabricated by varying rotational speed and friction pressure, by keeping forging pressure and friction time as constant. The microstructural study revealed ...... hiện toàn bộ
Characterization of Microstructure and Chemical Microinhomogeneity of HP40NbTi Cast Alloy After Different Crystallization RatesSpringer Science and Business Media LLC - Tập 10 - Trang 675-683 - 2021

The mechanism of formation of chemical inhomogeneity of phases during crystallization at the melt cooling rate in the range of 1–1000 K/s in the heat-resistant HP40NbTi alloy is studied by optical microscopy, electron microscopy, electron microprobe analysis, and x-ray mapping. The forming process of the phase’s chemical compositions in a multicomponent HP40NbTi alloy during crystallization is com...... hiện toàn bộ
Microstructural Development in Inconel 718 Nickel-Based Superalloy Additively Manufactured by Laser Powder Bed FusionSpringer Science and Business Media LLC - Tập 11 - Trang 88-107 - 2022

Excellent weldability and high temperature stability make Inconel 718 (IN718) one of the most popular alloys to be produced by additive manufacturing. In this study, we investigated the effects of laser powder bed fusion (LPBF) parameters on the microstructure and relative density of IN718. The samples were fabricated with independently varied laser power (125–350 W), laser scan speed (200–2200 mm...... hiện toàn bộ
Effect of Heat Treatment on the Microstructure and Property of Aerospace Punch DiesSpringer Science and Business Media LLC - Tập 8 - Trang 314-328 - 2019
Athil Al-Ezzi, Abeer A. Shehab
The purpose of this paper is to investigate the effect of heat treatment on the microstructure and property of punch dies used for precision stamping on aerospace mechanical parts. Many structural investigations were applied to identify the morphological characterization of high-speed steels with two technology variants: ordinary metallurgy (M2 and M42) and powder metallurgy (S390 PM). The results...... hiện toàn bộ
