The project will be conducted in three phases. To understand the process-structure-property relationships, computational modeling is to be utilized to predict the quantitative mechanical properties such as tensile, yield, elongation and fatigue strength. In this study, the L-PBF AM process will be used to manufacture near net shape AM Ti-6Al-4V test specimens, and evaluate the effect of post-processing heat treatment types on tensile and fatigue properties, compared to the baseline Ti-6Al-4V alloy bar, forging and casting material properties. Therefore, the effects of heat treatment types coupled with part thickness and resulting mechanical properties need to be thoroughly investigated. For example, annealing heat treatment provides lower tensile properties compared to the solution heat and aged heat treatment. On the other hand, the tensile properties are also depends on heat treatment types. Therefore, tensile properties are higher for a part with small grains even though both part had same heat treatment types. The thickness of the part affects the grain size of the part during solidification as such the grain sizes are smaller for the small thickness compared to the thick part. The current standard ASTM F2924 of the AM Ti-6Al-4V alloy mechanical properties in all direction requires minimum tensile properties (130 ksi UTS/120 ksi YS/10% Elong) regardless of heat treatment types and part thicknesses. The use of AM titanium alloy replacement of a currently used traditional titanium alloy in the US Army helicopters with a same traditional alloy heat treatment types may not provide an increased utilization of the AM titanium alloy and may cause additional performance risk since heat treatment for AM titanium alloy is not optimized. In the past few decades, there is an increasing interest to produce metallic AM parts for structural and non-structural applications, as these materials show acceptable performances compared to the traditional materials with shorter lead times, less material usage and near net-shape parts. Recent developments in AM technology and AM Standards offer great potential to implement AM produced part in the US Army. Current applications mainly focus on secondary structures or other non-critical applications. The quantitative process-structure-property relationships will be determined with computational modeling with respect to build orientation.ĭESCRIPTION: Additive Manufacturing (AM) is a new production technology that enables reduced manufacturing steps, part consolidation and production of near net shape parts from 3-D model data. The resulting mechanical properties and microstructures will be compared to the traditional Ti-6Al-4V alloys bars, forgings and castings. These heat treatments are Mill-Anneal (MA), ANNeal (ANN), Solution Treat and Age (STA) and Beta Solution Treat and Overaged (BSOA). Tensile testing, smooth bar high cycle fatigue testing and microstructural analyses are to be performed on Laser Powder Bed Fusion (L-PBF) manufactured near net shape Ti-6Al-4V specimens having four heat treatment types after Hot Isostatic Pressing (HIP).

SLOAN ROYAL DUAL FILTER BYPASS 1.0 URI PLUS
Sloan G2 Optima Plus Flushometers activate via multi-lobular infrared sensor to provide the ultimate in sanitary protection and automatic operation. A battery powered infrared sensor sets the flushing mechanism after the user is detected and completes the flush when the user steps away. Touchless sensor operation eliminates the need for user contact to help control the spread of infectious diseases. The flushometer is provided with an override button to allow a courtesy flush for individual user comfort. Sloan installed batteries speed installation and provide years of metered flushing to control the use of water and energy.
