An evaluation of the suitability of ERTS data for the purposes of petroleum exploration
This experiment was designed to determine the types and amounts of information valuable to petroleum exploration extractable from ERTS data and the cost of obtaining the information using traditional or conventional means. It was desired that an evaluation of this new petroleum exploration tool be made in a geologically well known area in order to assess its usefulness in an unknown area. The Anadarko Basin lies in western Oklahoma and the panhandle of Texas. It was chosen as a test site because there is a great deal of published information available on the surface and subsurface geology of the area, and there are many known structures that act as traps for hydrocarbons. This basin is similar to several other large epicontinental sedimentary basins. It was found that ERTS imagery is an excellent tool for reconnaissance exploration of large sedimentary basins or new exploration provinces. For the first time, small and medium size oil companies can rapidly and effectively analyze exploration provinces as a whole

Combination of Cladding Processes with Subsequent Hot Forming as a New Approach for the Production of Hybrid Components
A new process chain for the manufacturing of load-adapted hybrid components is presented. The "Tailored
Forming” process chain consists of a deposition welding process, hot forming, machining and an optional heat
treatment. This paper focuses on the combination of laser hot-wire cladding with subsequent hot forming to
produce hybrid components. The applicability is investigated for different material combinations and component
geometries, e.g. a shaft with a bearing seat or a bevel gear. Austenitic stainless steel AISI 316L and martensitic
valve steel AISI HNV3 are used as cladding materials, mild steel AISI 1022M and case hardening steel AISI 5120
are used as base materials. The resulting component properties after laser hot-wire cladding and hot forming such
as hardness, microstructure and residual stress state are presented. In the cladding and the heat-affected zone, the
hot forming process causes a transformation from a welding microstructure to a fine-grained forming
microstructure. Hot forming significantly affects the residual stress state in the cladding the resulting residual
stress state depends on the material combination.Mechanical Engineerin
