Introduction After the initial molding of the ceramic, whether by slip casting or dry pressing, it is still necessary to densify the compacted powder samples (green bodies) to form a continuous 3D structure and thus to
16. THE SONIC OR ACOUSTIC LOG 16.1 Introduction
homepages.see.leeds.ac.uk16.1 Introduction The sonic or acoustic log measures the travel time of an elastic wave through the formation. This information can also be used to derive the velocity of elastic waves through the formation. Its main use is to provide information to support and calibrate seismic data and to derive the porosity of a formation. The main uses are:

Their numbering system is not included in the 200, 300 or 400 groups. Precipitation hardening stainless steels contain alloying additions such as aluminum which allow them to be hardened by a solution and aging heat treatment.

As hot metal tends to oxidize, sufficient protec-tion from oxidation must be provided by the welding process to prevent this detrimental reaction with ambi-ent oxygen. Some metals are far more sensitive than others, in which case protection from oxidation becomes more demanding.

nvlpubs.nist.govUnderstanding the microstructure of AM materials, i.e. parts made by AM processes, is important for industry to have confidence in AM parts. The focus of this report is to assess the existing microstructure standards for metals to determine if the existing standards are sufficient for characterizing AM metals.
Introduction to Friction Stir Welding (FSW) - NASA
ntrs.nasa.govFSW Background Friction Stir Welding is a solid-state process that was patented in 1991 by The Welding Institute (TWI) of Cambridge, England [5]. This patent is now expired. Since its invention the process has generated significant interests in the R&D community. By 2007, 1800 patents had been issued relating to Friction Stir Welding [6].
