Specimen size effect on fracture toughness of Pyrowear 53 steel for planetary gears

Abstract A fracture toughness is one of the critical parameters for Pyrowear 53 steel which is widely used in planetary gears of aircraft vehicles. Due to a limited volume of planetary gears, it is impossible to directly assess their plain strain fracture toughness K Ic . Therefore, the main aim of...
