Compositional Effects on the Chemorheological Properties and Forming Behavior of Aqueous Alumina-Poly(vinyl Alcohol) Gelcasting Suspensions
… etc.) and suspension rheology on deposition behavior was investigated. Continuous printablity was achieved for tip diameters ranging from dt = 0.254 -- 1.370 mm for all mixing rates (Rmix 5 -- 300 rpm) and suspension compositions (i.e., fAl2O3 = 0.45, &phis;PVA = 0.275, [Ti] 0 -- 6.30 x 10--3 …

Retrogression-reaging and hot forming of AA7075
The retrogression-reaging (RRA) and hot forming behavior of AA7075 were studied. AA7075 is a high-strength alloy used in applications where weight is of particular importance, such as in automobiles. Like many of the high-strength aluminum alloys, AA7075 requires elevated temperature forming to …

Segregation and embrittlement in metallic interfaces : bounds, models, and trends
… [1], wear resistance [2], and superplastic forming behavior [3], in addition to changes in many other properties. These materials are thus of technological interest as structural materials. However, the excess free energy associated with grain boundary formation drives rapid grain growth in …

Processing Behavior of Thermoplastics Reinforced with Melt Processable Glasses
This work was concerned with evaluating the behavior of thermoplastics reinforced with melt processable phosphate glasses processed by techniques including injection molding, compression molding, and thermoforming. Thermoplastic resins consisting of polyphenylene sulfide (PPS), polyetherimide (PEI) …

Three essays on spatial econometrics with an emphasis on testing
… and interactions play a crucial role in forming behavior, but also because of the challenging problems inherited from spatial dependence in Econometric models. Misspecifications of spatial dependence in regression models lead to misleading inferences and policy implications. In this …

Thermisches Kunststoffnieten - Verfahrensablauf, mechanische Eigenschaften, Versagensverhalten
Bauteilkonstruktionen mit integrierten Kunststoffnietverbindungen nehmen aufgrund der steigenden Anzahl artfremder Werkstoffkombinationen im Rahmen von Hybridbauweisen kontinuierlich zu. Als nicht lösbare und punktuell wirkende Verbindung wird das Kunststoffnieten insbesondere aufgrund seiner …
