Lecture 1. Material Properties 1. Background
ieda.ust.hk3 3. Properties of materials We shall concern ourselves with three types of issues: (a) Mechanical properties of materials (strength, toughness, hardness, ductility, elasticity, fatigue and creep). (b) Physical properties (density, specific heat, melting and boiling point, thermal expansion and conductivity, electrical and magnetic properties)

Grain Size and Its Influence on Materials Properties
www.heat-treat-doctor.comGrain size effect on properties Grain size has a measurable effect on most mechanical properties. For exam-ple, at room temperature, hardness, yield strength, tensile strength, fatigue strength and impact strength all increase with decreasing grain size. Machinability is also affected; rough machining favors coarse grain size while finish machining

CERAMICS: Properties 1 (Physical, Chemical, Mechanical)
www-personal.umich.eduMECHANICAL PROPERTIES Properties depend both on temperature and degree of crystallinity. 1. Mechanical properties versus melting temperature: Generally strength and modulus go up and down together. Modulus (E) at 25C linearly related to melting temperature (Tm). (Ceramics = 30-350 GPa, Metals = 50-200 GPa, Polymers = <50 GPa) 2.

Mechanical Analysis of Soil - Memphis
www.ce.memphis.eduIdentification of soil properties presents challenges to geotechnical engineers. Unlike steel or concrete, the material properties and behavior of soil are difficult to predict due to its variability and limitation on investigation. Mechanical Analysis of Soil As complex as it is, soil can be described simply.
