FE Materials Science

material processing, properties, and attributes

toughness measure of a material's ability to yield and absorb highly localized and rapidly applied stress
tough a material that is ___ withstands occasional high stresses without fracturing
Charpy test measures toughness by applying sufficient impact to cause failure to a notched specimen
creep continuous yielding of a material under constant stress
creep test test where low tensile load of constant magnitude is applied to a specimen and the strain is measured as a function of time; measures creep
Brinell Hardness Test test to measure hardness of specimen; diameter of depression is correlated to hardness
hardness measure of a material's resistance to plastic deformation; capacity of a surface to resist deformation
endurance/fatigue limit stress level threshold at which a material will withstand an almost infinite number of loadings without experiencing failure
fatigue failure failure in which a material is stress-loaded repeatedly even without it ever exceeding the ultimate strength
ductility ability of a material to yield and deform prior to failure
brittle characteristic of a material that can only support small strains before failing catastrophically
strong characteristic of a material with a high ultimate strength
weak characteristic of a material with a low ultimate strength
hard characteristic of a material with a high modulus of elasticity
soft characteristic of a material with a low modulus of elasticity
Gold great reducing agent
Potassium great oxidizing agent
hard working forming process in which material's temperature is above its re-crystallization temperature
cold working forming process in which material's temperature is below its re-crystallization temperature
quenching forming process in which a formed part is submerged in a gas or liquid; prevents the material from forming undesirable characteristics often aiming for hard steel
hard working forming process in which internal defect and imperfections are eliminated; has a greater ductility; withstands large strains with out strain hardening
cold working forming process that promotes hardness and toughness; uniform microstructure
annealing forming step in which the temperature of the formed part is raised slightly about its recrystallization temperature to relieve stresses, increase grain size and recrystallize grains
