strength - What is the physical reasoning behind metal becoming . . . 12 I was wondering that if a proper process of heat treatment (heating to a temperature above upper critical temperature, then soaking and then quenching) is applied to a metal like steel, then what happens within the metal itself on microscopic level which makes it more strong and hard but decreases its toughness?
materials - Brittle = highly stiff but not very strong - Engineering . . . Brittle is characterized by sudden failure without fore-warning as exhibited by the more flexible material I think "stiff is a better word to describe a "strong" but brittle material The design of the modern car is well balanced in between flexibility and rigidity, so it can dampen the impact force during a collision, but not deform to an extent that causes excess body harm and threaten the
heat treatment - Is hardened steel better than tough steel . . . Toughness is a bit more difficult to quantify than strength but in general is the ability to resist impact and resistance to brittle fractures Ductility plays a part in toughness as it tends to help a material to resist crack propagation For simple steels heat treating is usually a balance between hardness and toughness
Whats the Difference Between LT and T Directions? What is the difference between LT and T directions in MMPDS (formerly MIL-Handbook 5)? I hand understood that forming metal orients its grains, destroying the isotropic nature of 'pure metal' and
How to find yield strength and Young Modulus from S-S curve What you will need to do depends on the application and the underlying theoretical assumptions E g , for the young's modulus you can compute tangent moduli at each point and take the average, or compute the secant modulus between two points
Difference between elastic limit and yield stress The elastic limit is of the material that behaves elastically in the stress vs strain curve The yield stress is of the material, beyond which, the material is said to be out of its elastic range
