Kirk, D. Dr., Coventry Universitiy, "Principles of Peening Intensity Selection", The Shot Peener, Summer 2015, Volume 29, Issue 3, pp. 26-34
(..) "What peening intensity should I apply to my component? (..)
"Peening intensity" is, of itself, a confusing term. We all know how it is quantified - as the arc height at a particular point on a "saturation curve" produced using one of three thicknesses of Almen strips. But what does that really imply?
Watanabe, Y., Asakawa, M. and Iwanaga, H., "Roll bending technologies for producing highly accurate compression rings for automobile engines", WIRE JOURNAL INTERNATIONAL, July 2015, pp. 58-61
Compression piston rings are produced by four-roll bending using a high-tensile steel alloy. This research was conducted to improve the compression ring dimensions by using FEM analyses and experiments. It was found that distortion and gap defect phenomena were reduced by an adequate setup for the roll.
Wright, Dr. R. N., "Tips from WireDrawing 101® - Wire Drawing Temperature - Part 9", Wire & Cable Technology, July/August 2015, p68
We are in the midst of a series of columns addressing the effects of temperature on lubrication, recovery and re-crystallization, residual stress, dynamic strain aging and martensite formation. In the last column, we introduced the topic of residual stress, with emphasis on phenomenology and impact on wire properties. In this column, we will discuss the difficult subject of residual stress measurement.
