I have a question about source hardening: what is the reason for a decrease on the yield strength in the case of the 1-(Un-irradiated) Body centre cubic (bcc) 2- (irradiated) face centre cubic (fcc)
What is the context of the question, i.e., what is the environment of the materials? And what type of material - steel?matt222 said:I have a question about source hardening: what is the reason for a decrease on the yield strength in the case of the 1-(Un-irradiated) Body centre cubic (bcc) 2- (irradiated) face centre cubic (fcc)
Material yield strength is the amount of stress or force that a material can withstand before it starts to deform permanently. This is an important mechanical property that helps determine a material's suitability for a specific application.
Material yield strength is determined through a tensile test, where a sample of the material is pulled until it reaches its elastic limit and starts to deform. The amount of stress required to cause this deformation is then recorded as the material's yield strength.
The main factors that affect material yield strength include the type and composition of the material, its heat treatment and processing, and any external factors such as temperature, pressure, and loading conditions.
Material yield strength and tensile strength are two different mechanical properties. While yield strength represents the stress at which a material starts to deform permanently, tensile strength is the maximum stress a material can withstand before breaking. Yield strength is typically lower than tensile strength.
Material yield strength is important in engineering and design as it helps determine the safety and reliability of a structure or product. By knowing the yield strength of a material, engineers can select the appropriate material for a specific application and design products that can withstand the expected loads and stresses without permanent deformation.
