Experimental and numerical crushing analyses of thin-walled magnesium
The weld itself did not influence the failure and the energy dissipation of the respective structure. For the alloy and process development of wrought magnesium, prospective improvements towards higher dissipated energy can be realised by increasing not only the strength but also the hardening rate of the material.

Manganese steel wear liners
Austenitic manganese steel – steel alloyed with more than 10% manganese – is work-hardening. That means that high impacts – like those in a crushing chamber for example – cause the formation of a extremely hard surface layer that is two to three times harder than the rest of the alloy If impacted enough, this results in a hard exterior layer backed by a …
Crushers
Crushers. It is difficult to define exactly the meaning of the terms crushing and grinding, or crushing and pulverization; the finer crushing stages may embody a certain amount of pulverizing or grinding, but in the main, crushing may be said to cover the reduction of stones or ores to a size of ½ inch, and in some cases slightly less.
