Application of creep small punch testing in assessment of creep lifetime
Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2009Abstract In this contribution, the problem is investigated, whether the dependence of the time to rupture on the acting force in small punch tests can be analyzed in the same way as the dependence of time to rupture on the applied stress in conventional tensile creep tests.

Small Punch Creep Test: An Overview
Metals and Materials International, 2020Small punch creep (SPC) test has an important role in the remaining life calculation of in-service components functioning at high temperature and harsh ambience. Since the extraction of conventional full scale specimens from the components in service impairs its integrity, SPC test can be used as an alternative technique. This test method requires very

A direct assessment of creep life based on small punch creep test
Theoretical and Applied Fracture Mechanics, 2019Abstract The uniaxial creep test (UCT) has generally been used to identify creep properties of materials. However, it consumes an enormous amount of testing time and requires a substantial specimen volume. The small punch creep test (SPCT) is introduced as an alternative test method to overcome the shortcomings of the UCT.

Small Punch Testing for Creep: Progress in Europe
Volume 9: Eighth International Conference on Creep and Fatigue at Elevated Temperatures, 2007 The small punch or disk bend test has particular value in life prediction of operating equipment since the test requires very small amounts of material (a common test specimen disk is 0.5 mm thick with a diameter of 6 to 10 mm), and usually the required volume of material can be acquired from operating equipment in a virtually nondestructive manner ...

A Direct Methodology for Small Punch Creep Test
Experimental Mechanics, 2015Small punch creep test (SPCT) has strong advantages in practice compared with traditional uniaxial creep test because a small sheet specimen (10 × 10 × 0.5 mm) can be obtained from in-service facilities or mechanical components without damage. In this paper, a novel investigation is proposed to directly interpret SPCT results in consideration of ...

Determination of creep behaviour of Ti60 alloy by small punch creep test
Materials at High Temperatures, 2016AbstractThe small punch (SP) creep test has distinct advantages in the creep property assessment of materials at elevated temperatures. However, there are few creep properties of Ti alloys obtained by the SP creep test in the current literature. In this paper, the SP creep behaviour of Ti60 alloy has been evaluated under various loads in the range 550 ...

Small punch creep testing: Review on modelling and data interpretation
Materials Science and Technology, 2013In many situations where the characterisation of the mechanical behaviour of a specific material is required, source material for manufacture of conventional test specimens may be at a premium. Examples include the validation of new alloys for use in the power industry, the description of the heat affected zone (HAZ) of weldments 1 or performing a ...

Notch sensitivity of Sanicro 25 in small punch creep test
Theoretical and Applied Fracture Mechanics, 2019Abstract Small punch creep tests of unnotched and notched 8 mm discs of new austenitic steel Sanicro 25 were performed at 700 °C. Side notches through the disc thickness proposed by Lacalle of different lengths ranging from 3.0 to 4.5 mm were applied for this study.

Qualification of P91 welds through Small Punch creep testing
Journal of Nuclear Materials, 2011 The deployment of the martensitic alloy P91 in future nuclear plant components operating in the creep regime depends very much on the performance of joints, found occasionally susceptible to failure in fossil fuel fired plant A completely novel approach is proposed to assess the integrity of P91 weldments which relies on the determination of the creep ...
