“…The DBTT has been determined as the abscissa corresponding to the average value M between the upper (U) and the lower (L) values in the plot. The DBTT of several steels have been determined by FIMEC [19]. Table 2 compares the DBTT values of three martensitic steels obtained from FIMEC and Charpy tests performed by using standard ISO-V and sub-sized (3 mm × 4 mm × 27 mm) KLST specimens.…”

The paper reviews the fundamentals of indentation theory for punches with cylindrical geometry, presents a deep-indentation finite element (FE) simulation and discusses an experimental technique for flat-ended cylindrical indentation. This technique is based on the use of cylindrical punches with diameters up to 1 mm and allows pressure-penetration curves to be drawn from which yield stress and elasticity modulus can be determined. Several materials have been tested including pure metals, steels and refractory alloys; yield stress has been determined and compared with literature values. By testing at different temperatures it was also possible to determine the ductile-to-brittle transition temperature (DBTT) for some alloys that show such phenomenon.

“…Experiments have been performed on several metals (Table 1). From tests performed at different temperatures it is also possible to have an indication about the ductile-to-brittle transition temperature (DBTT) for those metals which show such phenomenon [19]. The specific characteristics of FIMEC are:…”

“…Under these conditions, the following relationship, valid for several metal alloys [18], can be applied to estimate the yield strength (σ y ) and the load p y evaluated through FIMEC test: The values of p y /3 and σ y for the base metal and welded joints are compared (see Table 2). The same Table also shows the welding efficiency of the welded joints, assumed to be the ratio between yield strength of welded joint and of the base metal.…”

A Weldability Study of Al–Cu–Li 2198 Alloy

et al. 2014

View full text Add to dashboard Cite

Al-Cu-Li alloys, conceived for automotive and aeronautic applications thanks to the high mechanical resistance/density ratio, exhibit weldability issues common to all light alloys. In this paper, the weldability of Al-Cu-Li 2198 alloy was studied by comparing features of welds carried out by two processes, the traditional arc welding and the friction stir welding (FSW). Welded joints were submitted to optical and SEM metallographic examinations with EDS microanalysis measurements. Mechanical characteristics were evaluated through microhardness tests and the instrumented indentation test FIMEC (Flat-top cylinder Indenter for MEchanical Characterization).

“…The FIMEC test (Donato et al, 1998) is based on the penetration, at constant rate, of a flat punch of small size (a diameter of 2 mm and a height of 1.5 mm). During the test, the applied load and the penetration depth are measured, therefore load vs. penetration (LP) diagrams can be recorded.…”
