Lanxide Process
The Lanxide process, also known as pressureless metal infiltration, is a way of producing metal-matrix composite materials by a process of partial reaction; the process involves a careful choice of initial alloy (usually aluminium with about 3% magnesium and about 10% silicon), and then the maintenance of conditions in which the polycrystalline reaction product has a mechanical composition such that metal is drawn up through it towards the oxidiser by capillary action, so the composite material grows downwards. The process can be used for near-net-shape casting, including in protocols where the final casting has a cavity in the shape of the casting pattern - in that case, the metal is poured into the cavity, which has been arranged to lie in the middle of a quantity of "filler" corresponding to the reaction product, and wicks itself to fill the pores in the filler. The normal application is to produce alumina-reinforced aluminium; the process also allows the growth of ceramic laye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Near-net-shape
Near-net-shape is an industrial manufacturing technique. As the name implies, the initial production of the item is very close to the final, or ''net'', shape. This reduces the need for surface finishing. By minimizing the use of finishing methods like machining or Grinding (abrasive cutting), grinding, near-net-shape production eliminates more than two-thirds of the production costs in some industries. Processes The following are various near-net-shape processes categorized by material.

Lotus Elise
The Lotus Elise is a two-seat, rear-wheel drive, mid-engined roadster conceived in early 1994 and released in September 1996 by the British manufacturer Lotus Cars. The Elise has a fibreglass body shell atop its bonded extruded aluminium chassis that provides a rigid platform for the suspension, while keeping weight and production costs to a minimum. It is capable of speeds up to . The Elise was named after Elisa Artioli, the granddaughter of Romano Artioli who was chairman of Lotus and Bugatti at the time of the car's launch. Production of the Elise, Exige and Evora ended in 2021, to be replaced by a new family of models. Series 1 The 1996 Lotus Elise weighed . Because of this low weight, it was able to accelerate 0- in 5.8 seconds despite its relatively low power output of . Braking and fuel consumption are also improved by the car's reduced weight. Cornering is helped by a low center of gravity height of 470 mm (18½"). Series 1 was designed by Julian Thomson, then ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
