Testing of Small-Sized Specimens

September 26, 2014

Author(s)

Enrico Lucon

An extensive review of the current state-of-the-art of small specimen test technology (SSTT) has been presented, covering a number of experimental techniques aimed at characterizing the mechanical properties of materials and components through the use of

Fracture Toughness Characterization of High-Pressure Pipe Girth Welds Using Single-Edge Notched Tension SE(T) Specimens

August 28, 2014

Author(s)

Enrico Lucon, Timothy S. Weeks, James Gianetto, W. R. Tyson, D. Y. Park

The safety and reliability of large-diameter pipelines for the transport of fluid hydrocarbons is being improved by the development of high-strength steels, advanced weld technologies and strain-based design (SBD) methodologies. Strain-based design imposes

Author(s)

Enrico Lucon

This Certification Report documents the procedures used to develop certified values of maximum force (Fm) and absorbed energy (KV) for the following KLST-type miniaturized verification Charpy V-notch impact specimens: SRM 2216 (low-energy level, Fm = 2

Certified Miniaturized Charpy Specimens for the Indirect Verification of Small-Size Impact Machines

June 27, 2013

Author(s)

Enrico Lucon

Small specimen test techniques are becoming ever more popular as the need increases to characterize mechanical properties by use of the smallest possible amount of material, due to various restrictions on material availability, irradiation, testing space

Effect of Electrical Discharge Machining (EDM) on Charpy Test Results from Miniaturized Steel Specimens

December 11, 2012

Author(s)

Enrico Lucon

Electrical Discharge Machining (EDM) is a manufacturing process whereby a desired shape is obtained through electrical discharges between an electrode and a workpiece, separated by a dielectric fluid. EDM produces a damage layer on the surface of the

Impact Testing - Yesterday and Today

November 13, 2011

Author(s)

Enrico Lucon, Christopher N. McCowan

The Charpy impact test is a standardized high strain rate mechanical test which determines the amount of energy absorbed by a material during impact fracture. This test is widely applied in industry, since it is easy to prepare and conduct, and results can

Evaluation of Bias for Two Charpy Impact Machines Using the Same Instrumented Striker

May 1, 2011

Author(s)

Christopher N. McCowan, Enrico Lucon, Raymond L. Santoyo

Two Charpy machines were used to test NIST verification specimens at three energy levels: low energy (≈ 15 J at -40°C), high energy (≈ 100 J at -40°C) and super-high energy (≈ 240 J at room temperature). The study evaluates the differences observed for the

Verification of the performance of the 100 kN table-top model test frame used for tensile testing

February 7, 2011

Author(s)

Enrico Lucon

The so-called 20 kips frame (MTS table-top machine), equipped with a 100 kN load cell with serial No. 850, was used in the period April-December 2010 to perform tensile tests on several steels. The main purpose of these tests was to establish benchmark

Acceptance of new batches of 9310 steel for the Charpy Machine Verification Program

Author(s)

May Ling Martin, Enrico Lucon

During FY2021, one of the NIST Charpy Contractors returned some 9310 steel blanks (rough-machined, oversized, unnotched specimens) that presented visible black surface defects (similar to gouges, some with raised strips of steel). On a couple of these
