brinell hardness
Metals; Heat treatment
A hardness number determined by applying a predetermined load to the surface of a test material by using a hardened steel ball. Diameter of the depression is measured, and hardness is calculated as ...
scleroscope
Metals; Heat treatment
A hardness test performed on a Shore Scleroscope Hardness Testing machine. This type of testing is used primarily for large parts that cannot be tested under Rockwell or Brinell.
shore hardness
Metals; Heat treatment
A hardness test performed on a Shore Scleroscope Hardness Testing machine. This type of testing is used primarily for large parts that cannot be tested under Rockwell or Brinell.
flame hardening
Metals; Heat treatment
A heat treating method used to harden the surface of some parts where only a small portion of the surface is to be hardened, because the part might distort with conventional carburizing or heat ...
austempering
Metals; Heat treatment
A heat treating process for ferrous alloys achieved by quenching at a rate fast enough to avoid formation of ferrite or pearlite, and is done from the austenitizing temperature into a heat extracting ...
