با سلام ، اگرچه می دونم که باید فارسی بنویسم، ولیکن تصمیم گرفتم مطالب و استانداردهایی را در احتیار دوستان قرار بدهم که متاسفانه فرصت ترجمه کردن آنها را ندارم.
THE SUCCESSFUL EMPLOYMENT OF METALS in engineering applications relies on the ability of the metal to meet design and service requirements and to be fabricated to the proper dimensions.The capability of a metal to meet these requirements is determined by the mechanical and physicalpropertiesofthe metal
Physical properties are those typically measured by methods not requiring the application of an external mechanical force (or load). Typical examples of physical properties are density, magneticproperties (e.g.permeability), thermal conductivity and thermal diffusivity, electrical properties (e.g.,resistivity), specific heat, and coefficient of thermal expansion. Mechanical properties, the primary focus of thisVolume, are described as the relationship between forces (or stresses) acting on a material and the resistance of the material to deformation (i.e., strains) and fracture. This deformation, however, may or may not be evident in the metal after
the applied load is removed. Different types of tests, which use an applied force, are employed to measure properties, such as elastic modulus, yield strength, elastic and plastic deformation (i.e., elongation), hardness,fatigue resistance, and fracture toughnes
