On the Relation between Material Property and Part Performance by Ma Mingtu* in Crimson Publishers: Peer Reviewed Material Science Journals
The relation between material property and part performance is discussed. Concepts about material property and part performance are expounded. The factors influenced part performance is listed. It is of importance to deeply understand the idea about the relation between material property and part performance in practice.
Material property is mechanical property including yield strength, tensile strength, elongation, reduction of area, impact toughness etc. With these parameters as the characterization of material property is good or bad. Material property is usually related to material compositions, microstructure. Parts performance refers to some related indicators which meet application requirements of parts, such as the stiffness of parts, strength, fatigue strength and fatigue life, and so on. The function of the parts usually is characterized by “performance” in English. Which is related to the properties of the material, also is related to the manufacturing process of parts. With the development of material science and technology and the deep understanding of people for the material microstructure, material properties concept and category are extended. For example, the toughness of the material is not a simple to characterize with impact value; Now many parameters i.e. The fracture toughness, dynamic fracture toughness, formability, hydrogen embrittlement and delayed fracture resistance have been introduced. Metallurgical technology property and application technology performance of materials, such as smelting, casting, rolling, welding, etc. should been also considered.
