Abstract The high‐temperature oxidation of additively manufactured and chemically vapor infiltrated (3D‐printed SiC) has been compared to chemical deposited (CVD) SiC. 100‐h isothermal exposures were conducted at 1425° 1300°C 1 atm under both dry air steam environments. A SiC reaction tube was utilized reduce silica volatility. After 1300°C, on the 3D‐printed surface, which intrinsically rougher than CVD scales 70%–90% thicker convex regions concave/flat regions. In regions, large cracks...
This work introduces a meshed debonding model intended for use with tristructural isotropic (TRISO) fuel particles. The ability to better examine the potential effects of interface between coating layers will enable host investigations stress state when complex loading and interactions coated particles are taking place. In this work, is discussed in detail. Then, simulations presented show capabilities limitations model. First, traditional high-temperature gas reactor TRISO particle...
This work presents a discussion on series of finite element analyses that assess stress evolution in the coating layers tristructural isotropic (TRISO) particles contact with each other while embedded matrix. The initial simulations were applied uniaxial pressure versus matrix elastic modulus. These predicted increasing silicon carbide TRISO decreasing second set focused effects heating and cooling associated dimensional change state layers. general finding was there no significant...
