Quenching-rate determination for standard steel tensile specimens

A vertical tube furnace and a four-channel digital storage oscilloscope have been used to determine quench rates for standard tensile specimens of a martensitic stainless steel 1.4914. The quenching media examined were air, oil and water. Theoretical calculations were made, based on convection heat-...

Beschreibung
Zusammenfassung:A vertical tube furnace and a four-channel digital storage oscilloscope have been used to determine quench rates for standard tensile specimens of a martensitic stainless steel 1.4914. The quenching media examined were air, oil and water. Theoretical calculations were made, based on convection heat-transfer approaches, which quantify the heat flow from the specimen surfaces during cooling. Experimental data are in reasonable agreement with predicted values. Graphs. 7 ref.--AA
