Innovative Additive Manufacturing Process for Successful Production of 7000 Series Aluminum Alloy Components Using Smart Optical Monitoring System

2020-01-13004/14/2020

Aircraft components are commonly produced with 7000 series aluminum alloys (AA) due to its weight, strength, and fatigue properties. Auto Industry is also choosing more and more aluminum component for weight reduction. Current additive manufacturing (AM) methods fall short of successfully producing 7000 series AA due to the reflective nature of the material along with elements with low vaporization temperature. Moreover, lacking in ideal thermal control, print inherently defective products with such issues as poor surface finish alloying element loss and porosity. All these defects contribute to reduction of mechanical strength. By monitoring plasma with spectroscopic sensors, multiple information such as line intensity, standard deviation, plasma temperature or electron density, and by using different signal processing algorithm, AM defects have been detected and classified. For composition analysis, the ratio of the maximum intensities of Mg(I)/Al(I) shows a strong trend with the amount of Zn and Mg in the powder, and the results are extremely promising regarding the ability to use the online spectra for real time determination of the composition of the AA7075 powders with high accuracy. A test matrix based on DOE was built and response surface analysis was performed to get a regression formulae. The formula was utilized to control porosity during the process. Minimizing porosity level, process parameters can be further optimized and verified with the regression formulae. Having optimized process parameters, a preliminary design of in-process control system is followed, incorporating spectral signal data, such as Mg(II)/Mg(I), peak-line intensity ratio of Mg/Al, and so on.

Investigation of Dry Sliding Wear Behavior of AA8011 Reinforced with Zirconium Oxide and Aluminium Oxide Hybrid Composites Processed through Multi-Direction Forging

2019-28-005710/11/2019

The Cardinal goal of this research work is to fabricate hybrid composites of AA8011 with reinforcement particles of Zr2O3 and Al2O3 which was taken in equal (5wt%) weight percentage. The hybrid composites were cast in a square shape (50x50x50 mm size) under the optimal stir casted process parametric condition, further, it was taken for the forging process. The prepared specimens were induced for uni-direction (x), bi-direction (x and y) and multi-direction (x,y, and z) forging route and the response of microhardness of 53, 68, 81 and 96 VHN were obtained respectively due to microstructural phase changes with an even distribution of particles in the matrix. Thus, the tribological properties of prepared specimens were tested using pin-on-disc Tribometer at room temperature under dry sliding condition of load 5,10,15,20 N and by adjusting the sliding speed as 266 and 531 rpm respectively. The outcomes uncovered all the specimens that the wear rate increments with an increase in load and coefficient of friction show an increase at most extreme load conditions. Wear rate increments with increment in the sliding distance and Coefficient of friction also increment in sliding speed. As a result, it was concluded that multi-directional forged hybrid metal matrix composite was far better than uni and bi-directional forging specimens. The prepared specimen was prescribed for high precision parts inferable from its better tribological executions.

Properties and Limitation of an Oxide Coated Aluminum Brake Rotor

2018-01-187710/5/2018

The electrification of the powertrain and the thereto related recuperation of the electric engine saves the energy in the battery and thus reduces the thermally dissipated brake energy, which leads to lower brake rotor temperatures compared to combustion engine vehicles (ICEVs). These new conditions enable to reconsider brake disc concepts. Including lightweight design in heavy battery electric vehicles (BEVs) and the increasingly reliant corrosion resistance of brake rotors, Aluminum is a promising approach for new brake disc concepts. In the past, Aluminum brake disc concepts have already been deployed. For instance Aluminum Metal-Matrix Composite (Al-MMC) concepts in the Lotus Elise S1 and on the rear axle of the Volvo V40 [1]. The presented concept is a different approach and separates the friction system from the bulk Aluminum brake disc, achieved by coating of the friction rings. By locally reinforcing the friction rings, the good machinability and ductility of the base body is maintained and simultaneously the friction surface is sufficiently protected to resist the frictional loading during a brake application. In this work, fundamental studies on a brake dynamometer were conducted and supplemented by microstructural investigation to identify damage mechanisms and to judge the technical application of the concept.

New High-Performance Materials Tailored Specifically For Additive Manufacturing Processes

F-0074-2018-12814

5/14/2018

ABSTRACT Integrated Computational Materials Engineering (ICME) technologies have served an integral role in understanding, evaluating and designing material microstructures and heat treatments specifically tailored for the unique processing conditions of Additive Manufacturing (AM). Applying their Materials by Design® methodologies, QuesTek Innovations has expanded their ICME framework under US Army Small Business Innovation Research (SBIR) funding to adapt their high performance Ferrium® C64® gear steel to AM processes, demonstrating printability across multiple systems, achievement of AMS minimum tensile properties, and positive response to heat treatment. Under Office of Naval Research and US Navy SBIR funding, QuesTek has designed and is developing high performance, aluminum alloys that are both printable and demonstrate properties of wrought 6000 and 7000 series alloys. AM builds and testing to date have demonstrated crack-free printability, high strength and good corrosion resistance. QuesTek is also demonstrating its high strength titanium alloys in wire and powder AM processing and showing a 20% increase in strength at a given ductility versus Ti-6Al-4V. These technologies, among several other AM alloy development programs at QuesTek, are advancing into TRL 4 and beyond. QuesTek's work in stainless steel in AM is also covered.
