Small punch tests to estimate the mechanical properties of steels for steam power plant: II. Fracture toughness

Creep damage in small punch creep specimens of Type 304 stainless steel

“…Development of the method has been driven by the need to measure in-service degradation of mechanical properties with a limited volume of available material [2]. In the past decade, the small punch test has been used successfully to characterize the mechanical strength, impact toughness, and fracture properties of materials with specimens measuring only 0.5 mm in thickness by Bulloch [3][4][5], Dobes [6][7][8], Baek et al [9], Fleury [10,11], Ule [12], and Komazai et al [13], Yang and Wang [14] presented a numerical model in which the primary and the secondary creep stages were calculated but creep damage was not considered.…”

Assessment of the constitutive properties from small ball punch test: experiment and modeling

“…As example of the extrinsic reasons, we stress the need to reduce as much as possible the dose to personnel for post-irradiation testing. Among the test techniques employed to characterize the constitutive behavior and the fracture properties of irradiated materials, the ball punch test has been extensively used [5][6][7][8]. For the time being, only test recommendations for small punch tests have been issued that are not always followed by the workers.…”

Mechanical characterisation of a P91 weldment by means of small punch fracture testing

“…(3) with T charpy replacing T SP . It is important to note that in Ha and Fleury's work a difference of not more than 10 C is reported between FATT charpy and T charpy as derived from mean energy [6]. In the present work, T charpy values for base metal and weld metal are calculated as À65 C and À42 C, respectively.…”
