Abstract
VDC is an air-hardening 5% chromium die steel recommended for a wide range of hot work applications requiring resistance to heat and abrasion, and is particularly useful for white metal die casting and extrusion applications. It is equivalent to AISI TYPE H13. This datasheet provides information on composition and hardness as well as fracture toughness. It also includes information on heat treating, machining, and joining. Filing Code: TS-45. Producer or source: Latrobe Steel Company.
Abstract
PLATINUM is a soft, ductile, white metal which can be readily worked either hot or cold. It has a wide range of industrial applications because of its excellent corrosion and oxidation resistance and its high melting point. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: Pt-1.

This article discusses the problem of identifying metals and alloys as a material for the manufacture of folk jewelry in the Middle East and North Africa in the 19th-20th centuries. Changes in the composition of metal in traditional jewelry in this period are analyzed. General recommendations are given for determining the material of jewelry and approximate dating of items.
Abstract
Recommendations for shop cleaning and priming practices are broken down into seven categories: methods of surface preparation, methods of application, workmanship, supervision, inspection, priming, and fabrication. Surface preparation methods discussed include solvent cleaning, hand cleaning, power tool cleaning, flame cleaning, brush-off blast cleaning, commercial blast cleaning, white metal blast cleaning, and pickling. Application methods considered include brush, spray, hot spray, airless spray, roller, and dip.

For the purpose of discussion the platform and the alignment must be regarded as two separate sites which might in the future prove to have been related. Taken together the metal objects from the two sites represent a remarkable collection, not only by their context and numbers but also by the range of metals represented. Whilst the majority of the objects are in copper alloy (almost certainly bronze) there are also objects in iron, a white metal (some definitely tin, others, lead) and a single gold object.
Kedulan Site is the buried and ruined 9th century Mataram Hindu Kingdom temple, located in Tirtomartani Village, Kalasan District, Sleman Regency, Yogyakarta Special Province. This temple was incidentally discovered by sand diggers on 24 November 1993 under several meter thick of fluvio-volcanic deposit of the modern Merapi. Several technical studies were needed to carefully excavate the temple, including geology and geophysical approaches. One of the geophysical method have been applied was ground penetration radar (georadar). This method uses radar technology to obtain a continuous profile of the shallow sub-surface and thus allows scientists to image soil substratums based on differing dielectric constants. Georadar investigation by Department of Geological Engineering, Faculty of Engineering, Universitas Gadjah Mada, was conducted on 4 December 2007. The main purpose was to identify the location of the outer stone fence as an estimation to define the temple site area to be excavated. About one line was chosen to cross the site in north-south direction in a distance of 328 m. Two runs were completed on the same line but different courses, i.e. forward and backward, where one was checked with another. The result indicates the presence of the outer stone fence was possibly buried in a depth of 7 m. It was located about 40 m distance outside the inner stone fence. Assuming the fences were quadrangle relative to the main temple, hence it is estimated that the site area to be excavated is about 13.830 m² and total 96.808 m³ gravels and sands to be removed.
