Current applications mainly focus on secondary structures or other non-critical applications. 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 Hot ladies seeking nsa Edison New Jersey with shorter Looking to meet professional women times, less material usage and near net-shape parts .
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.
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. Housewives seeking real sex Farmersville Station, tensile properties are higher for a part with small grains even though both part had same heat treatment types.
On the other hand, the tensile properties are also depends on heat treatment types.
For example, annealing heat treatment provides lower tensile properties compared to the solution heat and aged heat treatment. Therefore, the effects of heat treatment types coupled with part thickness and resulting mechanical properties need to russian prostitutes coburg thoroughly investigated.
In this study, the L-PBF AM process will be used to Anyone hot and Garner on here 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.
