Abstract:

A method is described by which tensile and long time creep properties may be correlated to hot hardness. The procedure was used on PH15-7MO - RH950 and Rene 41. The tensile and creep rupture properties were plotted against the time. Temperature parameter P T C log t with values for the constant C of 18 or 20 and where T is the absolute temperature in R degrees and T is a measure of the test time in hrs. A similar plot or hardness was made against the parameter P. Cross plotting the curves obtained yielded a straight line, which indicated the existence of a valid correlation. Author
