Description

The objective of this study was to perform mechanical testing on large scale heats of the advanced ODS 14YWT alloy to investigate the effects of processing parameters on mechanical properties. Mechanical properties tests were conducted on two heats of the advanced ODS 14YWT ferritic alloy: the 14YWT-SM11 was produced by extrusion at ORNL and OW4 was produced by HIP at UCSB. The 14YWT-SM11 showed very high tensile strength compared to OW4, but showed less ductility as a result. The fracture toughness transition temperature of 14YWT-SM11 was determined in two orientations and showed T{sub 0} = 48 C in the favorably ... continued below

Description

The objective of this study was to perform mechanical testing on large scale heats of the advanced ODS 14YWT alloy to investigate the effects of processing parameters on mechanical properties. Mechanical properties tests were conducted on two heats of the advanced ODS 14YWT ferritic alloy: the 14YWT-SM11 was produced by extrusion at ORNL and OW4 was produced by HIP at UCSB. The 14YWT-SM11 showed very high tensile strength compared to OW4, but showed less ductility as a result. The fracture toughness transition temperature of 14YWT-SM11 was determined in two orientations and showed T{sub 0} = 48 C in the favorably strong L-T direction while shifting by 63 C to T{sub 0} = 111 C in the weaker T-L direction. The fracture toughness transition temperature for OW4 was not determined but appeared to be within the range observed for 14YWT-SM11. The fracture toughness of 14YWT-SM11 at room temperature was 86.8 MPa{radical}m and 93.1 MPa{radical}m, which was much higher than that of OW4 (27.4 MPa{radical}m). The strain rate jump tests conducted on OW4 indicated that the creep properties were similar to MA957 at 750 C.
