By hot extrusion at 250°C and electrical pulse treatment (EPT) of 40 ?s duration 10 min processing time, a homogeneous matrix microstructure with an average grain size 0.91 ?m abundant Mg17Al12 phase was obtained in SiCp/AZ91 magnesium composite. Moreover, SiCp were helpful to promote the accumulation crystal defects precipitation phase. After 250°C, yield strength (YS) ultimate tensile (UTS) c...

In this study, single pass rolling (SPR) with varied reductions was conducted on pre-homogenized AZ91 alloys (H alloys) and ECAP-processed (HE alloys). The effects of reduction the microstructures mechanical properties HR (pre-homogenized rolled) HER (ECAP-processed were investigated. results showed that possessed much finer superior than alloys, which significantly influenced by reduction. bec...

Abstract Magnesium and its alloys are excellent implant material candidates with their biodegradable structure mechanical properties close to human bone. In order provide the desired strength in applications, corrosion resistance of materials is expected be high. this study, improve AZ31 AZ91 magnesium alloys, an electrostatic hydroxyapatite coating process was applied, optimum conditions were ...
