Projects in the Manufacturing and Materials Joining Innovation Center are broken down into four focus areas:
1. Material Performance: Materials are designed to have specific properties to carry out a certain role. Welding can alter or eliminate some of these properties. Ma2JIC projects aim to control and understand welding techniques, joint design, and/or service conditions so that the materials can maintain the designed properties.
2. Modeling: Experimental testing takes time and can result in high costs. The emphasis of modeling is a high priority of Ma2JIC projects. Physical models are used across multiple disciplines to quantitatively understand the temperature, stress, and microstructure evolution during welding. These techniques accelerate the development and implementation of materials and processes.
3. Process Innovation, Development, and Additive Manufacturing: Continuous process improvement is vital to high productivity and achieving high quality. As industry, materials, and applications change; modified and new joining techniques need to be developed. Ma2JIC takes into consideration new technology, process limitations, and industry requirements to optimize the joining process.
The fundamental challenges associated with AM processes used to fabricate metallic materials are nearly identical to those in joining and include heat/fluid flow, residual stress control, phase transformations under non-equilibrium conditions, and resultant properties. Thus, the researchers within Ma2JIC are ideally positioned to address these challenges as new materials are attempted to be fabricated with a wide range of AM processes.
4. Weldability Testing and Evaluation: The difficulty to join materials increases as the complexity of materials increases. Failure can occur when joining new materials due to the lack of weldability knowledge of the material. Ma2JIC research teams examine the material weldability to determine methods of joining these materials that result in high quality joints.
