a harder material. Using conventional methods to machine hard metals and alloys means increased demand of time and energy and therefore increases in costs; in some cases conventional machining may not be feasible. Conventional machining also costs in terms of tool wear and in loss of quality in the product owing to induced residual stresses during manufacture. With ever increasing demand for manufactured goods of hard alloys and metals‚ such as Inconel 718 or titanium‚ more interest has gravitated

The alloy steel is a material very resistant capable of withstanding forces of grate magnitude either tension or compression. Steel is not an element; it is an alloy of iron containing less than 1% carbon to make it stronger. The process of steelmaking had multiple changes in the last century to meet regulations based on the political

Superbowl commercial uses elements of the rhetorical triangle to persuade audiences into buying the Ford F-150 half-ton truck. Ford using military grade aluminum alloy for the body of the F-150 and using high strength steel for the frame revolutionized the half-ton truck category. The transition between steel and military grade aluminum alloy is a crucial change in the automobile industry. The advertisement provides an impressive example of logos by telling the audience the F-150 has a five star safety
