“…(i) the high simplicity of the apparatus and data treatment; (ii) the possibility to get information about the local material properties on a scale large enough to include many grains; thus, data represent bulk characteristics and are not influenced by those factors which dramatically affect micro-and nano-indentation tests; (iii) the large versatility in industrial applications such as the control of welding quality [20,21], the on-line monitoring of forging or extrusion processes, etc.…”

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.

“…All TIG and the 12 mm EB welds show coarse grain formation which is typical for solidification micro structures that form during the welding cycles [9,10,12]. Both 5 mm beam welds do not show this severe grain coarsening.…”

“…Fusion welding may be performed either by electron beam (with and without filler wire), laser beam, hybrid MIG/ laser [5][6][7], or by tungsten-inert-gas (gas tungsten arc) welding with filler wire. Mechanical properties and microstructure of some electron beam (EB) and tungsten-inert-gas (TIG) welds of reduced activation 8-9Cr-WVTa steels (like EUROFER) and 9Cr-MoVNb steels (like P91) have been already investigated in the past, even after neutron irradiation [8][9][10][11][12][13][14][15][16][17][18][19][20].…”

“…For the manufacturing of the HCSB using LAFM steel, different fabrication methods, such as machining, hot isostatic pressing (HIP), welding, etc., will be utilized. Among these, knowledge on joining technologies for LAFM steel is still insufficient even though many interesting results about welded joints of LAFM steel have been recently published [2][3][4]. In addition, since welding technologies would be the key factors for successful TBM fabrication, the development of various welding methods, such as electron beam welding (EBW), laser, tungsten inert gas (TIG), submerged arc welding (SAW) and shielded metal arc welding (SMAW), is on-going.…”
