Determination of the Effects of Elevated Temperature Materials Properties of Several High Temperature Alloys
This investigation was conducted to determine mechanical properties of several high performance alloys at room and elevated temperatures. The effects of temperature (up to 1900 F) and exposure (up to 1000 hours) at temperature on the tensile, compressive, bearing and shear properties were determined from measured stress-strain information in both the elastic and plastic range. The following materials were considered: 301 extra hard stainless steel; Ph157Mo(TH 1050); AM 355; Rene 41; and N-155. All material was from 0.050-inch sheet, except the material for the 1/8-inch diameter shear pins, which were fabricated from 1/4-inch plate. Heat treatment was in accordance with existing specifications for the materials, or other procedures approved by ASD to develop the optimum strength properties. Descriptions of the test specimens, equipment, and procedures are included. Test results are reported in tables and in curves showing the effects of temperature and time on the various mechanical properties.
