Title: Laser peening: A tool for additive manufacturing post-processing

Abstract

Additive manufacturing (AM) is rapidly moving from research to commercial applications due to its ability to produce geometric features difficult or impossible to generate by conventional machining. Fielded components need to endure fatigue loadings over long operational lifetimes. This work evaluates the ability of shot and laser peening to enhance the fatigue lifetime and strength of AM parts. As previously shown, peening processes induce beneficial microstructure and residual stress enhancement; this work takes a step to demonstrate the fatigue enhancement of peening including for the case of geometric stress risers as expected for fielded AM components. We present AM sample fatigue results with and without a stress riser using untreated baseline samples and shot and laser peening surface treatments. Laser peening is clearly shown to provide superior fatigue life and strength. We also investigated the ability of analysis to select laser peening parameters and coverage that can shape and/or correctively reshape AM components to a high degree of precision. We demonstrated this potential by shaping and shape correction using our finite element based predictive modeling and highly controlled laser peening.

Non-destructive residual stress distribution measurement in nano-structured ultrahigh-strenght gear steels.

Conference Qian, Y ; Almer, J ; Lienert, U ; ...

The well-established enhanced fatigue performance associated with beneficial compressive residual stresses has been broadly applied in the development of new engineering materials, particularly gear and bearing steels. Residual stress enhancement processes, such as shot/laser peening, have also been investigated to maximize their benefits on fatigue strength. However, the measurement of residual stress distributions still heavily relies on the conventional X-ray technique, involving destructive material removal, tedious data correction and time-consuming data collection, which slows new material design and process optimization. To overcome this problem, we employ novel, non-destructive synchrotron techniques with high-energy x-rays to measure the distribution of residual strain/stressmore »« less
Lasershot peening--a means to strengthen metals

Thesis/Dissertation Chen, H-L

Lasershot peening is an emerging modern process that impresses a compressive stress into the surfaces of metals, improving their operational lifetime. Almost everyone is familiar with taking a strip of metal or a wire and bending it multiple times until it breaks. In this situation, when the metal is bent, the surface of outer radius is stretched into a tensile state. Under tension, any flaw or micro-crack will grow in size with each bending of the metal until the crack grows through the entire strip, breaking it into two pieces. Flexure of metal components occurs in most applications. The teethmore »« less

Microstructural variation through weld thickness and mechanical properties of peened friction stir welded 6061 aluminum alloy joints

Journal Article Abdulstaar, Mustafa A., E-mail: mustafa.abdulstaar@gmail.com ; Al-Fadhalah, Khaled J. ; Wagner, Lothar - Materials Characterization

The current study examined the effect of microstructure variation on the development of mechanical properties in friction stir welded joints of 6061-T6 aluminum alloy, which were subsequently processed by shot peening (SP). Following to FSW, fatigue specimens were extracted perpendicularly to the welding direction. Surface Skimming to 0.5 mm from crown and root sides of the joint was made and SP was later applied on the two sides using ceramic shots of two different Almen intensities of 0.18 mmA and 0.24 mmA. Microstructural examination by electron back scattered diffraction (EBSD) indicated variation in the grain refinement of the weld zone,more »« less

Investigation of Laser Peening Effects on Hydrogen Charged Stainless Steels

Thesis/Dissertation Zaleski, Tania M.

Hydrogen-rich environments such as fuel cell reactors can exhibit damage caused by hydrogen permeation in the form of corrosion cracking by lowering tensile strength and decreasing material ductility. Coatings and liners have been investigated, but there were few shot-peening or laser peening studies referenced in the literature with respect to preventing hydrogen embrittlement. The surface compressive residual stress induced by laser peening had shown success in preventing stress corrosion cracking (SCC) for stainless steels in power plants. The question arose if the residual stresses induced by laser peening could delay the effects of hydrogen in a material. This study investigatedmore »« less

On the effect of deep-rolling and laser-peening on the stress-controlled low- and high-cycle fatigue behavior of Ti-6Al-4V at elevated temperatures up to 550?C

Journal Article Ritchie, IAltenberger, RKNalla, YSano LWagner, RO - International Journal of Fatigue

The effect of surface treatment on the stress/life fatigue behavior of a titanium Ti-6Al-4V turbine fan blade alloy is investigated in the regime of 102 to 106 cycles to failure under fully reversed stress-controlled isothermal push-pull loading between 25? and 550?C at a frequency of 5 Hz. Specifically, the fatigue behavior was examined in specimens in the deep-rolled and laser-shock peened surface conditions, and compared to results on samples in the untreated (machined and stress annealed) condition. Although the fatigue resistance of the Ti-6Al-4V alloy declined with increasing test temperature regardless of surface condition, deep-rolling and laser-shock peening surface treatmentsmore »« less
