A phase-sensitive eddy current system was used to measure the presence of ferrite in an austenitic stainless steel matrix. Measurements were made on pressed powder specimens and on a weld in Type 304L stainless steel. The data obtained showed that small amounts of ferrite, on the order of 1 to 3%, could easily be detected. Variation in ferrite with position within the weld was also detected with good reproducibility. Absolute values for the ferrite content were not obtained as accurate standards for calibration were not available. (auth)

A computer program to solve the conservation equations of twodimensional elastic-plastic flow has been implemented at LLL on the CDC 7600 machine. The program, named HEMP, is written in an expanded FORTRAN IV language. This user's manual explains the operation and use of the program. A section is provided that will aid in converting the program to other machines and systems. (auth)
