An investigation on the tribological behavior of AZ91 and AZ91 + 3 wt% RE magnesium alloys at elevated temperatures

Materials & Design, 2014
The wear behavior of AZ91 and AZ91 + 3 wt% RE magnesium alloys was investigated under a normal load of 20 N at the wear testing temperatures of 25–250 °C and sliding speeds of 0.4 and 1 m s−1. As the sliding speed increased from 0.4 to 1 m s−1 at the wear temperature of 25 °C, the wear rates of AZ91 and AZ91 + 3 wt% RE alloys decreased by about 8% and ...

Producing Ultrafine-Grained AZ91 from As-Cast AZ91 by FSP

Materials and Manufacturing Processes, 2010
In 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, 2013
The 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 ...

Comparative study of tensile and high-cycle fatigue properties of extruded AZ91 and AZ91–0.3Ca–0.2Y alloys

Journal of Materials Science & Technology, 2021
Abstract Mg–Al–Zn–Ca–Y alloys with excellent ignition and corrosion resistances—termed SEN alloys (where the letters “S,” “E,” and “N” stand for stainless, environmentally friendly, and non-flammable, respectively)—have been developed recently. In this study, the microstructure, tensile properties, and high-cycle fatigue properties of an extruded Mg ...

Effect of Heat Treatment on Hardness Behavior of AZ91 and AZ91 Reinforced Carbon Nanotube

Applied Mechanics and Materials, 2015
In the present work the effect of heat treatment on the hardness behavior of AZ91 and AZ91 reinforced carbon nanotube were investigated under FESEM, Xrd and Rockwell hardness tester. Cnt was embedded homogenously into the matrix due to successfully mechanical alloying using planetary milling.
