Component annealing base

Abstract: Apparatus for supporting a charge in a high temperature annealing furnace which comprises a plurality of components arranged in combination for easy replacement of any component or the entire assembly. The apparatus includes a refractory tray which is sealed from the gaseous atmosphere of the heating chamber by a unique arrangement of the component parts of the base assembly including separable top and bottom plates and a compartmented seal trough.

Connection for a lightweight steel frame system

Abstract: The invention is directed to a lightweight steel frame system having end nailed connections where lightweight steel structural members frame into support members. The end nailed connection is made by driving fasteners through the support member and directly into the connection end of a lightweight steel structural member without the need for using additional connection hardware. Where the lightweight steel structural member is a roof or floor truss, the support member may include a leveling member to facilitate positioning each roof truss at an elevation set point to produce a level roofline along the finished structure.

Kinetics of the martensite transformation in athermal Fe-C-Ni-Cr alloys

Abstract: An investigation was conducted to study the martensite transformation kinetics of athermal Fe-C-Ni-Cr alloys. The transformation rate was found to be dependent on alloy composition and was a function of i) the rate of change of chemical free energy with temperature, and ii) the energy expended in deforming the austenite surrounding a growing martensite embryo in order to accommodate the transformational volume and shear strains. Increasing either of the two factors leads to an increase in transformation rate. Also, it was found that the magnitude of the contribution of the deformation energy to the overall nonchemical free energy associated with the transformation depends on the alloy system and specific composition.
