Effect of Relatively Low Levels of Porosity on the Plasticity of Metals and Implications for Profilometry-Based Indentation Plastometry
R Reiff-Musgrove, W Gu, JE Campbell, J Reidy, A Bose, A Chitrapur, Y Tang, M Burley, TW Clyne
Jul 05, 2022
Herein, the effect of dispersed (relatively low levels of) porosity within a metal on its plastic deformation is examined. Stainless steel samples, made via additive manufacturing, are used in the work. It's found that porosity...
Indentation Plastometry of Welds
W Gu, J Campbell, Y Tang, H Safaie, R Johnston, Y Gu, C Pleydell-Pearce, M Burley, J Dean, TW Clyne
Feb 14, 2022
This investigation concerns the application of the profilometry‐based indentation plastometry (PIP) methodology to obtain stress–strain relationships for material in the vicinity of fusion welds. These are produced by The...
Indentation Plastometry for Study of Anisotropy and Inhomogeneity in Maraging Steel Produced by Laser Powder Bed Fusion
This work concerns the use of profilometry‐based indentation plastometry (PIP) to obtain mechanical property information for maraging steel samples produced via an additive manufacturing route (laser powder bed fusion). Bars are...
Indentation Plastometry of Particulate Metal Matrix Composites, Highlighting Effects of Microstructural Scale
R Reiff-Musgrove, M Gaiser-Porter, W Gu, JE Campbell, P Lewis, A Frehn, AD Tarrant, YT Tang, M Burley, TW Clyne
Jan 26, 2023
Herein, it is concerned with the use of profilometry‐based indentation plastometry (PIP) to obtain mechanical property information for particulate metal matrix composites (MMCs). This type of test, together with conventional...
Use of Profilometry-Based Indentation Plastometry to Study the Effects of Pipe Wall Flattening on Tensile Stress–Strain Curves of Steels
Herein, the flattening and subsequent tensile testing (in the hoop direction) of steel pipes used for transmission of oil and gas are concerned. A particular focus is on the use of a novel indentation plastometry test (PIP)...
A Constitutive Stress–Strain Law for Metals with Sigmoidal Curves
A formulation is proposed for true stress–true strain relationships in the plastic regime that exhibit sigmoidal shapes, such as those of certain metastable austenitic stainless steels (MASS). It contains two terms, broadly...
Profilometry-Based Indentation Plastometry Testing for Characterization of Case-Hardened Steels
S Ooi, R Reiff-Musgrove, M Gaiser-Porter, M Steinbacher, I Griffin, J Campbell, M Burley, M Warwick, H Vaka, C Fang, TW Clyne
Mar 18, 2023
An attraction of the profilometry‐based indentation plastometry (PIP) procedure is that, while it involves interrogation of volumes sufficiently large to ensure that bulk properties are obtained, it still allows stress–strain...
