Scanning electron micrographs of the 410 martensitic steel depicting the carbide population. (a) As-received specimen, and (b) specimen crept to failure, 49 hours at 200 MPa/620° C.

Schematic of the effect of cell distortion of a BCC cell along the c-axis and corresponding x-ray patterns for the BCC and BCT unit cells
Grahic Jump Location
X-ray patterns obtained for the as-received 410-martensitic stainless steel and two creep samples
Grahic Jump Location
Magnetic hysteresis curves of the as-received and creep-tested specimens. Intermediate Creep: 100 hrs @ 500° C, 100 MPa; Full Creep: 49 hrs @ 620° C, 200 MPa. Magnetic measurements were made at room temperature and zero nominal stress.
Grahic Jump Location
Magnetic hysteresis curves of the as-received and creep tested specimens for the 12.7 mm diameter 410-martensitic stainless steel, showing differences detected for different locations on sample. Measurements were made at room temperature and zero nominal.
Grahic Jump Location
SEM micrographs of regions in the necked area of the 12.7 mm diameter 410 stainless steel rod. Sample was exposed to creep rupture at 100 MPa/620° C for 120 hours. Arrows point to locations of voids. Carbides were found within the grains and the grain boundaries.
