Effects of Crystal Orientation on the Crack Propagation of Sapphire by Sequential Indentation Testing

Effects of Crystal Orientation on the Crack Propagation of Sapphire by Sequential Indentation Testing

Single-crystal sapphire (α-Al2O3) is a hard and brittle material. Due to its highly crystalline nature, the fracture behavior of sapphire is strongly related to its crystal structure, and understanding the effects of crystal structure on the crack propagation of sapphire is essential for the success...
