Microstructure and properties of 2B16 aluminum alloy electron beam welding joints after artificial aging

The effects of artificial aging on mechanical properties and damping capacity of ZA84 magnesium alloy with rare earth element (RE) were studied.

The microstructures and tensile properties of artificial aging and natural aging a new aluminum matrix sliding bearing alloy TZS88 were investigated by SEM,metallograph analysis,hardness and tensile tests.

The production process institutions of 6005A-T6 aluminium alloy sheet and plate were determined as following: the quenching temperature is 520℃,the temperature and time of artificial ageing is(165±5)℃ 8 h.

Effects of artificial ageing on the hardness distributions and strength were analyzed for 6063 aluminum alloy joints welded by varying heat inputs.

By artificial ageing,the grain boundaries could be appeared while the grain size is kept unchanged.

In this paper,the microstructure and mechanical properties of 6063 Al alloy at different aging temperature and time has been studied The research results showed that the aging process(175℃×1 5h+200℃×3h)is available to obtain higher hardness of thin walled fashioned alloy Its hardness can reach over 75HV after aging treatmen

Solid Solution Treatment and Artificial Aging of Mg-Al-Mn-RE Alloy;

The results are as follows: Microstructure of artificial aging and seasoning are both α(Al) matrix,Sn-phase and compounds;compared with the seasoning of TZS88 alloy,the tensile strength of the alloy using manual aged process increases by around 5 percent,and the hardness increases by 0.
