Texture Evolution in Low Carbon Steel Fabricated by Multi-directional Forging of the Martensite Starting Structuree
It has been clarified that deformation and annealing of martensite starting structure can produce ultrafine-grained structure in low carbon steel. This study aims to investigate the texture evolution and mechanical properties of samples with martensite structure deformed by two different forging processes. The martensitic steel samples were forged by plane strain compression and multi-directio...
متن کاملKinetics of SIMA AZ80 Magnesium Alloy
Semi-solid feedstock of AZ80 magnesium alloy modified by [trace] rare-earth Y element 10 (0, 0.2, 0.4, 0.8 wt.%) were fabricated by [strain-induced melting activation] (SIMA) in the form of 11 extrusion and partial remelting. The effect of Y addition on the microstructure evolution of [the] 12 extruded and [isothermally heat] treated alloy was observed by [using an] optical microscope (OM), 13 ...
متن کاملUltralow Temperature Anelasticity of Aluminum-Magnesium Alloys
Results of internal friction measurements on the commercial aluminum-magnesium alloys 5052,5086 and 5486 are reported here over the temperature range 50 mK to 300 K, and compared with published data on alloy 5056. Effects of heat treatment and explosive bonds on the internal friction are evaluated. The quality factor of proposed multi-layer aluminum-alloy spherical resonant-mass detectors of gr...
متن کاملCorrelation between the surface chemistry and the atmospheric corrosion of AZ31, AZ80 and AZ91D magnesium alloys
* Corresponding author. Tel: 34 1 3944348; Fax: 34 1 3944357 E-mail: [email protected] ABSTRACT X-ray photoelectron spectroscopy (XPS) was used in order to investigate the correlation between the surface chemistry and the atmospheric corrosion of AZ31, AZ80 and AZ91D magnesium alloys exposed to 98% relative humidity at 50oC. Commercially pure magnesium, used as the reference material, reveale...
متن کاملFatigue behaviour and fractography of extruded AZ80 magnesium alloys in very high cycle regime
In order to investigate the fatigue properties of extruded magnesium alloy in very high-cycle regime, rotary bending fatigue test was performed in ambient atmosphere at room temperature using the hourglass shaped specimens of AZ80 alloys extruded (Fspecimen) and treated by an artificial aging after extrusion (T5-specimen). From the experimental results, both specimens show a clear step-wise S-N...
