Silicon Carbide Dispersion Strengthening of Magnesium …

In this study, the silicon carbide dispersion strengthening of magnesium using the mechanical alloying (MA) method was investigated. The experimental results are summarized as follows. By increasing the milling energy of the ball mill in which the p Al 2 O 3 /Mg MA powder of a previous study was fabried, the density of the SiC p /Mg was able to be increased to a value higher than that of

A comparison of techniques for the metallographic …

Metallographic preparation of thermal spray coated samples is often difficult because hard and soft materials, which normally require different polishing techniques, are commonly present in a single spraycoated sample. In addition, the microstructures of many spray- deposited materials make them prone to pull-out damage during cutting, grinding, and polishing operations. This study compares
