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
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
Effect of carbon additions on microstructure and mechanical properties of Ti-15-3
Materials Science and Technology - Tập 20 Số 3 - Trang 343-349 - 2004
Z. Q. Chen, M. H. Loretto
Inverse ductile–brittle transition in metallic glasses?
Materials Science and Technology - Tập 31 Số 6 - Trang 635-650 - 2015
Yajuan Sun
There is evidence that metallic glasses can show increased plasticity as the temperature is lowered. This behaviour is the opposite to what would be expected from phenomena such as the ductile–brittle transition in conventional alloys. Data collected for the plasticity of different metallic–glass compositions tested at room temperature and below, and at strain rates from rate 10...... hiện toàn bộ
Research status and development of magnesium matrix composites
Materials Science and Technology - Tập 36 Số 6 - Trang 645-653 - 2020
Guohong Ma, Hao Xiao, Jia Ye, Yinshui He
Magnesium and its alloys, as the metal materials with the lowest density among structural materials, have attracted much attention due to their excellent properties such as high specific stiffness, good electromagnetic shielding properties and good vibration damping effects. However, its low strength, inherent brittleness and poor corrosion resistance limit its application in various indu...... hiện toàn bộ

D. P. Moon
Factors influencing gas turbine use and performance
Materials Science and Technology - Tập 3 Số 7 - Trang 554-561 - 1987
A. S. Radcliff
Effect of cooling rate on microstructure of Ti-6Al-4V forging
Materials Science and Technology - Tập 18 Số 12 - Trang 1471-1478 - 2002
O.N. Senkov, J. J. Valencia, S.V. Senkova, M. Cavusoglu, F. H. Froes
