(3DAP) was used to study the early stage of precipitation behavior of Cu-rich phase of Super304H aged at 650 ℃ for 1 h after solution treatment at high temperature. The coherency strain strengthening...; 文献标志码:A Strengthening effect of precipitate phase in Super304H austenitic heat......
of strength and elongation in the alloys is related to the refine grain strengthening, precipitation particles strengthening and substructure strengthening principles. Key words:Sc; Zr; Al-Zn-Mg-Cu alloy; microstructure; strengthening mechani 1 Introduction The microstructure and properties of aluminium alloys are strongly affected by adding small quantities of scandium. Minor Sc may improve......

Influence of Sc on high temperature strengthening behavior of Ti-6Al-4V alloy LIU Hui-qun(刘会群)1, YI Dan-qing(易丹青)1, WANG Wei-qi(王韦琪)2, WANG Li-ping(王立平)2, LIAN Cai-hao(廉才浩)1 1. School... of alloys increases with increasing Sc content after deformation at 850 ℃, however, there is no obvious strengthening of Sc when the alloys are deformed at 1 000 ℃. Sc exists as Sc2O3 forms by internal......
and Technology, 2001, 17(1): 15-24. [12] Avedesian M M, Baker H. Magnesium and magnesium alloys[M]. Ohio: ASM International, 1999: 10-241. [13] Akhtar A, Teghtsoonian E. Solid solution strengthening...: The strengthening mechanism of the rolled EW93 magnesium alloy through T5 heat treatment was investigated. The microstructures and mechanical properties of the alloy with cast-T6 and rolled-T5 temper were compared......
solution strengthening is the leading strengthening mechanism during the quench. It can be inferred that the more rapid the cooling rate, the higher the solid solubility. Furthermore, fine... decreases with the increase of cooling rate and the secondary phase is fine and dispersed. 3) The solid solution strengthening is the leading strengthening mechanism during the quench and the hardness......
rolling-on-line solution-cold rolling-aging condition exist in the form of Fe and Fe3P. Sub-structure strengthening coming from the thermo-mechanical treatment and precipitation strengthening of Fe... Fe and P in the alloy were also studied. The results show that, after hot rolling, on-line solution alloy is mainly a single-phase solid solution. However, there still is a small amount of dissolved......
and experimental verification, it is determined that the main strengthening mechanism of the alloy is solid solution strengthening and precipitation strengthening.
