| Abstract Scope |
Microwave casting is a modern technique of material casting. It utilizes microwave energy as a heat source for the melting and processing of materials. Microwaves transform radiation directly into heat energy inside the material, eliminating the need for external heating appliances. The casted structures are often used in engineering applications and may be exposed to dynamic loading conditions. So, it becomes important to measure the modal parameters of structural components after casting to avoid their dynamic failure. Nickel is widely used in various engineering applications due to their exceptional strength, corrosion resistance, and sustainability in extreme temperature conditions. In this regard, in the present work, specimens of Nickel of size 140 × 35 × 2 mm3 are cast using in-situ and ex-situ microwave casting. After casting, the specific damping capacities of microwave-processed specimens are measured experimentally using modal analysis. The natural frequencies and structural loss factors are also compared. |
