Chapter 9, Problem 10P

The individual turbine blades used in the exhaust region of jet engines must withstand high temperatures, high stresses, and highly corrosive operating conditions. These demanding conditions severely limit the material possibilities, and most jet engine turbine blades have been manufactured from one of the high�temperature superalloys. The fabrication processes are limited to those that are compatible with both the material and the desired geometry. Through the 1960s and early 1970s, the standard method of production was investment casting, and the resultant product was a polycrystalline solid with thousands of polyhedral crystals. In the 1970s, production shifted to unidirectional solidification, where elongated crystals ran the entire length of the blade. More recently, advances have enabled the production of single crystal turbine blades. Investigate this product to determine how the various material and processing conditions produce products with differing performance characteristics.

لانقطة واحدة of Warm working The advantages over cold working are: 1) forces and power are higher,2) more intricate work geometries possible, and 3) need for annealing may be reduced .or eliminated T F Blow molding is an important industrial process for making one- piece hollow plastic parts with thick .walls T Sly The sequence of the Blow Molding is automated and often integrated with downstream operations such .as bottle filling and labeling T لنقطة واحدة
Heat treatment is the controlled heating and cooling of metals to alter their physical and mechanical properties without changing the product shape. When performing the cooling step of the tempering process, knife makers have used material such as clay to cover portions of the blade to slow the cooling rate of the covered steel. Why may this technique be beneficial for making a sword which holds a sharp edge while remaining flexible enough to withstand the forces subjected to it in battle?
