Vacuum Carburizing
of Powder Metallurgy Steels
A classic. This article presented the fundamentals of vacuum carburizing
of PM steels and discussed the challenges
that issues such as density, changes in material composition and
machining played on case depth development. Derived from empirical
experiments, the fundamental formulas to determining case depth
as a function of time, temperature, carbon potential and density
are presented.

Heat Treatment of Fasteners - Tips for Equipment Operation
Most heat
treat shops have at least two different styles of furnaces: high-temperature
furnaces that are used for normalizing
and austenitizing; and low-temperature furnaces for annealing,
stress relief and tempering. In addition, they have one or more
quenching systems. The important process variables are discussed
in this article for these heat treatments including temperature,
time, atmosphere and cooling rates.
