General Motors-AISI AAC Advanced High Strength Steel Repairability Study Phase I Final Report Introduction The introduction of Advanced High Strength Steels (AHSS) to light vehicle body structure applications poses a significant challenge to organizations involved in the repair of vehicle structures. AHSS are typically produced by nontraditional thermal cycles and contain microstructural components whose mechanical properties can be altered by exposure to elevated temperatures. This temperature

The flour produced from the cassava plant‚ which on account of its low content of noncarbohydrate constituents might well be called a starch‚ is known in world trade as tapioca flour. It is used directly‚ made into a group of baked or gelatinized products or manufactured into glucose‚ dextrins and other products. Starchy foods have always been one of the staples of the human diet. They are mostly consumed in starch-bearing plants or in foods to which commercial starch or its derivatives have been

524 SILICON CARBIDE Vol. 22 SILICON CARBIDE 1. Introduction Silicon carbide [409-21-2] (SiC) is a technologically important material that is one of the small number of unusual materials that were first created synthetically and then subsequently discovered in nature. Silicon carbide was first observed in its natural form in 1905 by the Nobel-prize-winning chemist Henri Moissan‚ who discovered it in the meteor that created the Diablo Canyon in Arizona. The transparent mineral‚ now known as
