sON THE COVER:
An engineer checks the
placement of laser spots prior to
fully automated processing. Laser
peening of jet engine fan,
compressor, and (potentially)
turbine blades enables greater
fatigue lifetimes and reduced
inspection intervals. Courtesy of

Development of Ti 2 AlNb Alloys: Opportunities and Challenges W. Chen, J.W. Li, L. Xu, and B. Lu Ti 2 AlNb offers a well-balanced property profile for application in aerospace engines to significantly reduce weight. Overcoming Barriers of Magnesium Ignition and Flammability Frank Czerwinski The use of magnesium in commercial aircraft cabins is being reevaluated to save weight, as it is the lightest structural metal. Materials in Space: Exploring the Effect of Low Earth Orbit on Thin Film Solid Lubricants M.T. Dugger, T.W. Scharf, and S.V. Prasad Challenges facing materials used in space have not changed significantly over the past few decades, but today’s requirements have a different focus than those used in the heyday of space exploration. This article considers the effect of atomic oxygen exposure on thin film solid lubricants.
