Effect of the aging process and pre-deformation on the precipitated phase and mechanical properties of 2195 Al–Li alloy
Third-generation Al–Li alloys, represented by 2195 Al–Li alloy, have considerable application opportunities in lightweight aerospace structures. This work investigates the effect of the aging temperature, single/double aging strategies and pre-deformation on the precipitation behaviors of 2195 Al–Li...

520 | |a Third-generation Al–Li alloys, represented by 2195 Al–Li alloy, have considerable application opportunities in lightweight aerospace structures. This work investigates the effect of the aging temperature, single/double aging strategies and pre-deformation on the precipitation behaviors of 2195 Al–Li alloy. The influence and correlation between the precipitated phase and mechanical properties, especially the tensile strength, ductility and failure fracture mode, were further studied. The results indicate that increasing the aging temperature can significantly improve the aging kinetics, thereby precipitating the large size T1 phase and decreasing the number density accordingly. Double aging is beneficial to the uniform size and distribution of the precipitated phase, which reduces the unevenness of micro-deformation. The pre-deformation increases the number of nucleation sites of the T1 phase, thereby significantly reducing the average size and increasing the number density. Pre-deformation can directly increase the strain hardening by generating dislocations while indirectly increasing the precipitation strengthening by refining the size and increasing the number density of the T1 phase. The mechanical properties and fracture mode of materials are related to the dislocation density and the type, size, distribution and number density of the precipitated phase. | ||

This work investigates the effect of the aging temperature, single/double aging strategies and pre-deformation on the precipitation behaviors of 2195 Al–Li alloy. The influence and correlation between the precipitated phase and mechanical properties, especially the tensile strength, ductility and failure fracture mode, were further studied. The results indicate that increasing the aging temperature can significantly improve the aging kinetics, thereby precipitating the large size T1 phase and decreasing the number density accordingly. Double aging is beneficial to the uniform size and distribution of the precipitated phase, which reduces the unevenness of micro-deformation. The pre-deformation increases the number of nucleation sites of the T1 phase, thereby significantly reducing the average size and increasing the number density. Pre-deformation can directly increase the strain hardening by generating dislocations while indirectly increasing the precipitation strengthening by refining the size and increasing the number density of the T1 phase. The mechanical properties and fracture mode of materials are related to the dislocation density and the type, size, distribution and number density of the precipitated phase. 2195 Al–Li alloy Aging process Pre-deformation Precipitated phase Mechanical properties Huang, Liang verfasserin aut Xu, Jiahui verfasserin aut Su, Hongliang verfasserin aut Zhang, Huiping verfasserin aut Xu, Yike verfasserin aut Li, Jianjun verfasserin aut Wang, Yu verfasserin aut Enthalten in Materials science and engineering / A Amsterdam : Elsevier, 1988 832 Online-Ressource (DE-627)320500497 (DE-600)2012154-4 (DE-576)095299947 1873-4936 nnns volume:832 GBV_USEFLAG_U SYSFLAG_U GBV_ELV GBV_ILN_20 GBV_ILN_22 GBV_ILN_23 GBV_ILN_24 GBV_ILN_31 GBV_ILN_32 GBV_ILN_40 GBV_ILN_60 GBV_ILN_62 GBV_ILN_63 GBV_ILN_65 GBV_ILN_69 GBV_ILN_70 GBV_ILN_73 GBV_ILN_74 GBV_ILN_90 GBV_ILN_95 GBV_ILN_100 GBV_ILN_101 GBV_ILN_105 GBV_ILN_110 GBV_ILN_150 GBV_ILN_151 GBV_ILN_224 GBV_ILN_370 GBV_ILN_602 GBV_ILN_702 GBV_ILN_2003 GBV_ILN_2004 GBV_ILN_2005 GBV_ILN_2008 GBV_ILN_2011 GBV_ILN_2014 GBV_ILN_2015 GBV_ILN_2020 GBV_ILN_2021 GBV_ILN_2025 GBV_ILN_2027 GBV_ILN_2034 GBV_ILN_2038 GBV_ILN_2044 GBV_ILN_2048 GBV_ILN_2049 GBV_ILN_2050 GBV_ILN_2056 GBV_ILN_2059 GBV_ILN_2061 GBV_ILN_2064 GBV_ILN_2065 GBV_ILN_2068 GBV_ILN_2088 GBV_ILN_2111 GBV_ILN_2112 GBV_ILN_2113 GBV_ILN_2118 GBV_ILN_2122 GBV_ILN_2129 GBV_ILN_2143 GBV_ILN_2147 GBV_ILN_2148 GBV_ILN_2152 GBV_ILN_2153 GBV_ILN_2190 GBV_ILN_2336 GBV_ILN_2470 GBV_ILN_2507 GBV_ILN_2522 GBV_ILN_4035 GBV_ILN_4037 GBV_ILN_4112 GBV_ILN_4125 GBV_ILN_4126 GBV_ILN_4242 GBV_ILN_4251 GBV_ILN_4305 GBV_ILN_4313 GBV_ILN_4322 GBV_ILN_4323 GBV_ILN_4324 GBV_ILN_4325 GBV_ILN_4326 GBV_ILN_4333 GBV_ILN_4334 GBV_ILN_4335 GBV_ILN_4338 GBV_ILN_4393 51.00 Werkstoffkunde: Allgemeines AR 832 |

Effect of the aging process and pre-deformation on the precipitated phase and mechanical properties of 2195 Al–Li alloy |
abstract |
Third-generation Al–Li alloys, represented by 2195 Al–Li alloy, have considerable application opportunities in lightweight aerospace structures. This work investigates the effect of the aging temperature, single/double aging strategies and pre-deformation on the precipitation behaviors of 2195 Al–Li alloy. The influence and correlation between the precipitated phase and mechanical properties, especially the tensile strength, ductility and failure fracture mode, were further studied. The results indicate that increasing the aging temperature can significantly improve the aging kinetics, thereby precipitating the large size T1 phase and decreasing the number density accordingly. Double aging is beneficial to the uniform size and distribution of the precipitated phase, which reduces the unevenness of micro-deformation. The pre-deformation increases the number of nucleation sites of the T1 phase, thereby significantly reducing the average size and increasing the number density. Pre-deformation can directly increase the strain hardening by generating dislocations while indirectly increasing the precipitation strengthening by refining the size and increasing the number density of the T1 phase. The mechanical properties and fracture mode of materials are related to the dislocation density and the type, size, distribution and number density of the precipitated phase. |
