Effect of thermo-mechanical processing on the low impact abrasion and low stress sliding wear resistance of austenitic high manganese steels

Wear, 2019
The low impact abrasion and low stress sliding wear properties of two thermo-mechanically processed austenitic high manganese steels (Fe17Mn and Fe17Mn3Al) have been studied.

A MECHANISM OF CORNEAL ABRASION*

Optometry and Vision Science, 1970
ABSTRACT A patient overwore her contact lenses intentionally until an abrasion occurred so that the experimenter could study the tissue changes. On the basis of the observations, an hypothesis for the cause of abrasion is suggested, and several precautionary measures for avoiding abrasions are
