What Does SIM Stand For?

SIM stands for Stress Induced Martensite

SIM, or Stress Induced Martensite, refers to a specific phase transformation that occurs in certain alloys, particularly in shape memory alloys, when subjected to stress. This phenomenon involves the transition from austenitic to martensitic phase as a response to applied mechanical stress, resulting in unique properties such as enhanced shape recovery and improved mechanical performance. SIM plays a critical role in the functionality of materials used in various applications, including medical devices and smart actuators.
