in Cl- solution. Otherwise, it is found that copper cannot markedly affect the mechanical properties nor the shape memory effect(SME). As for the effects of copper on Fe-Mn-Si based alloys, the austenite strengthening is one of the key factors to improve SME.
Key words: FeMnSiCrNi; shape memory effect; corrosion resistance; copper; austenite strengthening

The strengthening contributions form solid solution strengthening, grain refinement, dislocation strengthening, precipitation hardening and dispersion strengthening were evaluated using standard equations... solution strengthening. Apart from these, the other components of strengthening that will be operative are dislocation strengthening attained due to sub-zero deformation and precipitation hardening......
dispersive spectrometer (EDS). The results show that the microstructure of Mg-Zn-Y quasicrystals reinforced AZ91 alloy consists of α-Mg supersaturating solid solution, β-Mg17Al12 phase... strengthening of magnesium alloys. Key words: Mg-Zn-Y quasicrystals; AZ91 alloy; mechanical properties; composite strengthening 1 Introduction At present, composite strengthening is one of the most......
Microstructural evolution during solution treatment of thixoformed AM60B Mg alloy HUANG Hai-jun, CHEN Ti-jun , MA Ying, HAO Yuan Key Laboratory of Gansu Advanced Non-ferrous Metal Materials... during solution treatment of AM60B Mg alloy prepared by thixoforming. The results indicate that the microstructural evolution includes two stages: the first stage involves rapid dissolution of eutectic......
alloy can be attributed to the grain refinement, precipitation strengthening and solid- solution strengthening [33,34]. While the grains become coarser which would weaken the YS and UTS according...Trans. Nonferrous Met. Soc. China 30(2020) 2650-2657 Microstructure modification and precipitation strengthening for Mg-6Zn-1Mn-4Sn-0.5Ca through extrusion and aging treatment Xia CHEN1,2, Ding-fei......
. The hardness value was HV 90 and the maximum compression resistance was 430 MPa. Therefore, the grain refinement strengthening, the second phase strengthening and the solid solution strengthening..., the solid solution strengthening and the second phase strengthening, we can further explain the improvement mechanism of the mechanical properties of the magnesium alloy solidified under high pressure......
is remarkably improved by the solution strengthening effect because of the addition of Ce. Key words: Mg-Li alloy; Ce; heat treatments; solution strengthening; tensile properties 1 Introduction Due.... However, the Al-Ce phase with high thermal stability remains in the alloy. Thereby, the effects of solution strengthening and precipitate strengthening can be obtained simultaneously, thus the tensile......
