“…Accordingly, many studies used the indentation hardness as a characterization method of mechanical properties of compacts (Bonaccorsi and Proverbio, 2006;Chtourou et al, 2002;Kuppuswamy et al, 2001;Tehrani et al, 2010) as well as an evaluation metrics of a compaction process (Chtourou et al, 2002).…”

For processes involving particulate materials, mechanical properties of green compacts are of great interest when they are final or intermediate products. Optimal quality of green compacts is achieved usually with empirical approaches, i.e., unexpected issues in processes or products' quality are usually mitigated by time and resource consuming trial-and-error methods. Issues of the powder compaction are commonly observed when there are problems in feed materials or operational conditions even without any substantial change in a formula. Such divergent behavior of particulate materials is especially problematic for product developments and reliable operations. It has been widely accepted hypothesis that properties of particles are determinants of mechanical behavior of powder during compaction and the quality of resulting compacts. With recent developments in nanotechnology, characterization and engineering of individual particles at a microscopic or sub-microscopic scale are now feasible. Leveraging recent technological advancements, there has been a good progress in regard to quantitative understanding of mechanical relationships between properties of particles, particle system and final product. This review highlights the recent developments and gaps in engineering mechanical quality of powder compacts in conjunction with the characterization of particle systems and compaction at multiple scales.

Scratch testing using nanoindentation helps to characterize material’s wear resistance and the accompanying material removal, and deformation mechanism. The effect of load and repeated scratching on pure zinc was investigated in this study. Surface examination post scratching revealed the formation of long chips at lower loads, which can be attributed to ductile-like behavior. Ploughing dominated at higher loads, while micro-cutting was active at lower loads. The material removal factor (fab) is an indicator of the prevailing wear mechanism. A good correlation appeared between the observed wear mechanism and the calculated fab, wherein interplay of ploughing and micro-cutting was observed. The decrease in wear rate as the number of passes increased and the decreasing value of fab are indicative of the strain hardening behavior during repeated scratching. The presence of intergranular fracture slip and twinning on the deformed surface is indicative of the material’s response to induced stress.
