Visual analysis of solidification and δ–γ transformations in steels
Materials Science and Technology - Tập 29 Số 5 - Trang 631-635 - 2013
X F Zhang, Yu‐ichi Komizo
The theory of solidification of steels and the kinetics of austenite to α-ferrite phase transformation were extensively studied; however, comparatively, little information is available concerning the kinetics of the δ-ferrite to austenite transformation due to the difficulty of making in situ observations. In the present study, a laser scanning confocal microscopy with an infrared image f...... hiện toàn bộ

Effect of heat treatment on tensile properties of friction stir welded joints of 2219-T6 aluminium alloy
Materials Science and Technology - Tập 22 Số 2 - Trang 237-241 - 2006
H. J. Liu, Y. C. Chen, Feng Ji
The effect of post-weld heat treatment (PWHT) on the tensile properties of friction stir welded (FSW) joints of 2219-T6 aluminium alloy was investigated. The PWHT was carried out at aging temperature of 165°C for 18 h. The mechanical properties of the joints were evaluated using tensile tests. The experimental results indicate that the PWHT significantly influences the tensile properties ...... hiện toàn bộ
High pwder Nd-YAG laser welding of SiC particle reinforced aluminium alloy 2124

Modification of residual stress and microstructure in aluminium alloy by cryogenic treatment
Materials Science and Technology - Tập 36 Số 14 - Trang 1547-1555 - 2020
Zeju Weng, Xuanzhi Liu, Kaixuan Gu, Jia Guo, Chen Cui, Junjie Wang
The effect of cryogenic treatment (CT) combined with solution and ageing treatment on the residual stress and microstructure of 7050 aluminium alloy was investigated. The relationship between residual stress and microstructure was discussed. The results showed that compared to solution–ageing treatment (SA), CT after solution and before ageing (SCA) exhibited lower level and higher unifor...... hiện toàn bộ
Gas tungsten arc welding of α + β titanium alloys: A review
Materials Science and Technology - Tập 25 Số 3 - Trang 309-324 - 2009
Andrew Short
Titanium alloys used in aerospace structures require joints of high integrity to meet the design requirements. Gas tungsten arc welding (GTAW), laser beam welding (LBW) and electron beam welding (EBW) are all processes capable of creating fusion welded joints. Gas tungsten arc welding offers the potential to achieve welds of equal quality to EBW or LBW at much lower capital costs; however...... hiện toàn bộ
Damage characterisation in aluminium matrix composites reinforced with amorphous metal inclusions
Materials Science and Technology - Tập 31 Số 5 - Trang 579-586 - 2015
A. Ferre, Sylvain Dancette, Éric Maire
Aluminium matrix composites with volume fractions of 1 and 4% of amorphous metal inclusions were prepared by mixing powders, spark plasma sintering (SPS) and hot extrusion. The reinforcing phase was a Zr57Cu20Al10Ti8Ni5 metallic glass (MG) and the matrix phase consisted of two types of...... hiện toàn bộ
Creep resistance of Fe–Ni–Cr heat resistant alloys for reformer tube applications
Materials Science and Technology - Tập 35 Số 16 - Trang 1924-1931 - 2019
Franck Tancret, Johanne Laigo, Jader Furtado
Relations between microstructure, phase transformations and creep resistance of austenitic Fe–Ni–Cr alloys are investigated. As-cast alloys with different silicon contents and an ex-service tube are submitted to laboratory agings to trigger specific phase transformations, and subsequently creep-tested at 950°C under stresses of 24–48 MPa. As-cast microstructures contain interdendritic chr...... hiện toàn bộ
