Physical Traits
The tendency of a material to fail suddenly.
Brittleness
This fuels the "Whisper Momma" Forge.
What is Propane?
The measure of the rate at which heat will flow through a material.
What is Thermal Conductivity?
The ability of a material to resist indentation, scratching or abrasion
What is hardness?
Carbon steel with 5% to 30% Carbon content.
What is Low Carbon Steel?
The resistance of a material to a force which is acting to pull it apart.
Tensile strength
Rapidly Quenching the high carbon steel from 1,600 (+/-) deg. F. increased these physical properties?
What is hardness and brittleness?
The ability of a metal to withstand a sharp, high-velocity blow without fracture.
What is Impact Strength?
The resistance of a material to a repeated or alternating stressing without failure:
Fatigue strength
Metals where iron is the main element.
What are Ferrous metals? (or maybe plain carbon OR mild steel...)
The physical effect of a stress, usually evidenced by stretching or other deformation of the material.
Strain
Hardness tester used in the machine Shop Lab to test softer metals such as aluminum or brass.
What is the Brinell Hardness Tester?
The rock, earth, or raw material in which we find metals.
What is Ore?
The stress point at which permanent deformation results.
Yield strength
A type of steel alloyed primarily with Chromium and Nickel.
What is Stainless Steel?
The ability of a material to be permanently deformed without failure:
Ductility
The scale we used to evaluate hardness with the hardness tester in the Machine Tool Lab.
What is the Rockwell "C-Scale" of hardness?
The ability of a material to resist the chemical attack by other elements and chemical compounds.
What is Corrosion Resistance?
The increse of a body (size or dimension) due to a change in it's temperature.
What is Thermal Expansion?
The general ability of a metal to withstand the shock of a rapidly applied load.
What is Toughness?
The maximum pulling force to which the material can be subjected without failure.
Ultimate Tensile Strength
These two things are required to forge weld.
What is Heat and Pressure?
Copper and Zinc in a 60%/40% respective ratio make this.
What is Brass?
The maximum stress to which a material can be subjected without permanent deformation or failure by breaking.
Elastic limit
A carbon Steel with 0.30% to 0.45% carbon content.
What is Medium Carbon Steel?
