..., or by a thermit reaction for joining heavy sections such as rails. Portability is a great advantage. Electric arc welding processes use electricity to produce the intense heat necessary for welding ( Fig. 1.6 ). Some electric arc processes use a consumable electrode that melts and becomes part of...

... strengths. Before 1895, there was no process for producing low-carbon chromium to be added to iron, an important factor in chromium steels. At this time, German chemist Hans Goldschmidt invented the thermite process, a process that combines chromium ore with aluminum powder to generate enough heat to...

..., which possess good elevated-temperature properties and can be welded easily but are not heat treatable. Tin and zirconium additions also strengthen the alpha phase, but they are not classified as alpha stabilizers, rather being classified as neutral additions. Additions of molybdenum, vanadium, iron...

... atomization, next in importance are chemical processes of powder production. These include reduction of oxides, precipitation from solution or from a gas, thermal decomposition, chemical embrittlement, hydride decomposition, and thermit reactions. The most widely used processes within this category include...
