Precipitates and intermetallic phases in precipitation hardening Al–Cu–Mg–(Li) based alloys
The present study contains a critical review of work on the formation of precipitates and intermetallic phases in dilute precipitation hardening Al–Cu–Mg based alloys with and without Li additions. Although many suggestions for the existence of pre-precipitates in Al–Cu–Mg alloys with a Cu/Mg atomic ratio close to 1 have been made, a critical review reveals that evidence exists for only two tru...
متن کاملStudy on Mg/Al Weld Seam Based on Zn–Mg–Al Ternary Alloy
Based on the idea of alloying welding seams, a series of Zn-xAl filler metals was calculated and designed for joining Mg/Al dissimilar metals by gas tungsten arc (GTA) welding. An infrared thermography system was used to measure the temperature of the welding pool during the welding process to investigate the solidification process. It was found that the mechanical properties of the welded join...
متن کاملThe Effect of Cu Additions on the Precipitation Kinetics in an Al-Mg-Si Alloy with Excess Si
The microstructural evolution during age hardening of a Cu-bearing Al-Mg-Si alloy has been investigated by the three-dimensional atom probe (3DAP) and transmission electron microscope (TEM) techniques, in order to clarify the effect of Cu on the initial age-hardening response. After 30 minutes of artificial aging at 175 8C, the alloy shows a significant increase in hardness. The TEM observation...
متن کاملDevelopment of hard intermetallic coatings on austenitic stainless steel by hot dipping in an Al-Si alloy
The austenitic stainless steel was coated by dipping into a molten Al-12.4%Si alloy at 765oC. The effect of immersion times in the range of 60 to 900 s was investigated with respect to the phase nature, thickness, and microhardness. An uniform layer (~12 m) of Al12(Fe,Cr)3Si2 intermetallic with hexagonal crystalline structure is formed, irrespectively the immersion time. Microhardness of the c...
متن کاملFatigue Behavior of an Ultrafine-Grained Al-Mg-Si Alloy Processed by High-Pressure Torsion
The paper presents the evaluation of the mechanical and fatigue properties of an ultrafine-grained (UFG) Al 6061 alloy processed by high-pressure torsion (HPT) at room temperature (RT). A comparison is made between the UFG state and the coarse-grained (CG) one subjected to the conventional aging treatment Т6. It is shown that HPT processing leads to the formation of the UFG microstructure with ...
