Producing Ultrafine-Grained AZ91 from As-Cast AZ91 by FSP
Materials and Manufacturing Processes, 2010In this investigation SiC particles were added to as-cast AZ91 magnesium alloy and AZ91/SiC surface nanocomposite layer with nano-grain structure was produced via friction stir processing (FSP). Effects of process parameters, such as the rotational and traverse speeds, the FSP pass numbers and the rotational direction of FSP tool on the powder ...

Corrosion Behavior of AZ91/AZ91-0.4%Nd Alloys in 3.5wt.% NaCl
Applied Mechanics and Materials, 2013The microstructure and corrosion behavior of commercial AZ91/AZ91-0.4%Nd alloys were investigated by OM, immersion test and weight-loss method. It was found that the number of Nd element in the AZ91 magnesium alloy has effect on the grain refining efficiency, the coarse β-Mg17Al12 phase distributed along the grain boundaries transformed into granular ...

Nowadays, magnesium alloys are increasingly used in automotive and aerospace applications mainly due to their light weight combined with reasonable mechanical properties. However, magnesium (alloys) matrix composites are manufactured in order to improve some of the monotonic mechanical properties. In the present work, the AZ91 (Mg-Al-Zn) alloy was used

Dry sliding wear behavior of globular AZ91 magnesium alloy and AZ91/SiCp composites
Wear, 2017Abstract Dry sliding wear behavior of rheocast AZ91 magnesium alloy and AZ91/SiCp composites reinforced with 5 and 10 vol% SiC particles were investigated under normal loads of 10–250 N and sliding speeds of 0.1, 0.3, 0.5 and 1 m/s using pin-on-disc configuration against a 1045 steel disc counterbody. In this work, rheocast alloys and composites have
