摘要：
Creep behavior of chromium steel (X20CrMoV 12 1) and of the low-alloy steel (14MoV 6 3) was studied at elevated temperatures. The tests were performed (i) in small punch arrangement at constant force and (ii) in conventional uniaxial mode at constant tensile stress. Time to fracture and the minimum deflection rate in small punch tests are related in a similar manner as the corresponding quantities in conventional creep tests. A formula is established for re-calculating the minimum creep rate from the minimum deflection rate. (C) 2002 Elsevier Science B.V. All rights reserved.
