= were similar to volume fraction of ferrite measured per ASTM E562. This influence of ramp-up to temperature during tempering has been quantified. The ramp-up time in the furnace prior to the establishment of steady state heat more » treatment conditions contributes to the extent of heat treatment performed.

As such, furnace temperature uniformity and control of furnace loading during tempering is critical to obtain the desired mechanical properties. Tempering success is dependent on both tempering time and temperature. Heat treatment procedure qualification (HTPQ) schema to demonstrate heat treatment success and to pre-qualify other alloys and section sizes requiring lesser hardenability have been developed. Quenching and hardenability concepts were also investigated. Use your rod near the starting portion of the game and start fishing ASAP. Typical austenitization temperatures and holding times used by steel foundries far exceed what is required for transformation to austenite. Time-temperature profiles of furnace control thermocouples can be very different from the time-temperature profiles observed at the center of casting loads in the furnace. Furnace load time-temperature profiles in steel foundries exhibit significant differences depending on heat treatment equipment, furnace loading practice, and furnace maintenance.

Foundry heat treatment trials to develop heat treatment procedure qualifications have shed light on the relationship between heat treatment theory and current practices. These studies highlight the relationships between critical heat treatment process control parameters and heat treatment success.
