The mechanical behaviors and damping capacities of the binary Mg−Ga alloys with Ga content ranging from 1 to 5 wt.% were investigated by means optical microscope (OM), scanning electron (SEM), X-ray diffraction (XRD), hardness test, tensile test dynamic analyzer (DMA). (HV0.5) increases increase content, which can be described as HV0.5=41.61+10.35c, solid solution strengthening effect Δσs alloy has a linear relationship cn, where c is molar fraction solute atoms n=1/2 or 2/3. exhibits...
To achieve the objective of enhancing yield strength (YS) quenching and partitioning (Q&P) steel without compromising tensile ductility, a stepped (SP) strategy was proposed for Q&P treatment on medium carbon silicon-rich steel. The optimized involves two-stage partitioning, first stage is conducted at temperatures above martensite start (Ms) temperature, followed by second carried out lower temperature an extended period, involving isothermal partitioning. Experimental results demonstrate...
GH4169 is primarily strengthened through precipitation, with heat treatment serving as a crucial method for regulating the precipitates of alloy. However, impact aging temperature on microstructure and properties has not been thoroughly studied, hindering effective regulation its properties. This study systematically investigated effects evolution mechanical alloy using various techniques such OM, SEM, XRD TEM. The results indicate that raising leads to an increase in sizes both γ″ γ′ phases...

The effects of Ga addition (1, 2, 3 and 5 wt-%) on the corrosion behaviour high strain rate rolled Mg–Ga alloys are firstly investigated by weight loss measurement electrochemical testing. Solute atoms can reduce potential but improve resistance alloy with content lower than wt-%. Mg–3Ga sheet is most corrosion-resistant 0.52 mg cm−2 day−1 for 7 days immersion in 3.5% NaCl solution. improvement be ascribed to enhanced compactness film associated addition. affects DRX degree, degree not...

The as-solutionized Mg-4Zn alloys, one candidate material for biological implantation, are featured with the Portevin-Le Chatelier effect during tensile testing strain rate of 6.67 × 10−7 s−1, which leads to higher corrosion and acceleration stress cracking. With increase strain, new slip bands generated proliferation dislocations is very rapid in bands. microgalvanic occurs between (anode) low dislocation density region (cathode). 0.1 wt% Sr addition can reduce impact on alloy, resulting...
The hot deformation behavior and microstructure evolution of TC18 titanium alloy under different conditions were studied by means compression, SEM EBSD. flow stress curves corrected friction temperature rise (double-corrected), the constitutive equation processing map established. results indicate that after correction rise, is lower than original stress. dynamic recrystallization (DRX) primary softening mechanism alloy. DRX content increases with decrease strain rate increase temperature....
In the course of basic research, thermal compression experiment is affected by many factors, this causes deviation stress-strain curve to measured. The effects temperature increase and friction on titanium alloy TC18 were investigated, strain-stress has been corrected, accurate constitutive equation hot working diagram are constructed, analysis was done microstructure's change rule. outcomes demonstrate: with TC18, actual stress lower than that Recrystallization dominates microstructure...
