An aluminum rod is a trapezoidal bar-shaped cast form of the liquid metal, which is further reduced to obtain a diameter of 9.6 millimeters up to 32 millimeters by the roller and drawing processes through a series of dies. Aluminum wire rods are used in various applications such as cables and conductors, because of their high electrical conductivity, low weight, and resistance to corrosion.

Welding is a fabrication process to agglutinate metals or thermoplastics using coalescence. The process is economical and it is an efficient method to fuse metal permanently. It finds application in a number of industries such as automotive, transportation, energy, construction, shipbuilding, mining equipment and heavy machinery, and aerospace and defense. The items used in this process are known as welding consumables, and can be broadly categorized as filler metals and flux. The metals that melt with the joining materials, and are consumed in the process are called filler metals. Flux is used to produce a gas shield around the weld pool that prevents oxidation of the hot metal.

Ferritic stainless steels are promising candidates for IT-SOFC interconnect applications due to their low cost and resistance to oxidation at SOFC operating temperatures. However, steel candidates face several challenges, including long term oxidation under interconnect exposure conditions, which can lead to increased electrical resistance, surface instability, and poisoning of cathodes due to volatilization of Cr. To potentially extend interconnect lifetime and improve performance, a variety of surface treatments were performed on AISI 441 ferritic stainless steel coupons prior to application of a protective spinel coating. The coated coupons were then subjected to oxidation testing at 800 and 850 degrees C in air, and electrical testing at 800 deg C in air. While all of the surface-treatments resulted in improved surface stability (i.e., increased spallation resistance) compared to untreated AISI 441, the greatest degree of improvement (through 20,000 hours of testing at 800 deg C and 14,000 hours of testing at 850 deg C) was achieved by surface blasting.

The research under this project focused on a theoretical and computational modeling of dislocation dynamics of mesoscale deformation of metal single crystals. Specifically, the work aimed to implement a continuum statistical theory of dislocations to understand strain hardening and cell structure formation under monotonic loading. These aspects of crystal deformation are manifestations of the evolution of the underlying dislocation system under mechanical loading. The project had three research tasks: 1) Investigating the statistical characteristics of dislocation systems in deformed crystals. 2) Formulating kinetic equations of dislocations and coupling these kinetics equations and crystal mechanics. 3) Computational solution of coupled crystal mechanics and dislocation kinetics.
