How can I improve the strength i know that i can greatly
increase the strength of a
material by processes such as
cold working or quenching, but
this causes a loss of
ductility. how can i increase
both the strength and
ductility of a cast iron
material?

Cast iron is hard brittle material and used in certain applications such as motor engine's block. Cold working or quenching are out of consideration due to the nature of the material. |

how do you measure ductility can ductility and conductivity
be really measure? If so,
how?and to be more specific
what is the ductility and
conductivity of stainless
steel, carbon steel, aluminum,
and copper?

conductivity is easy. Measure the resistance of the metal - conductivity = 1/ resistance ductility is a little more complicated. you would do a tensile test (pull a sample apart) establishing the force used against the extension of the material until it breaks. There will be a point when the metal "stretches" so much that is will not go back to its original shape from there on it behaves plastic or ductile. this can't be described in one number as it is a range. Look up the values for what you are asking in the internet.... Good luck. |

What is the difference between What does ductility and
malleability mean??
Thanks

*The difference between malleability and ductility is that malleability is the ability to deform easily upon the application of a compressive force, and ductility is doing the same with tensile force. *Ductility is a mechanical property used to describe the extent to which materials can be deformed plastically without fracture. In material science, ductility specifically refers to a material's ability to deform under tensile stress; this is often characterized by the material's ability to be stretched into a wire. Malleability, a similar concept, refers to a material's ability to deform under compressive stress; this is often characterized by the material's ability to form a thin sheet by hammering or rolling. Ductility and malleability do not always correlate with each other; for instance, gold is both ductile and malleable, but lead is only malleable. Commonly, the term "ductility" is used to refer to both concepts, as they are very similar. Go through the "external link" in the source link. |
