I. DESCRIPCION DEL CASO. • CASO 11.1: METALSA hace de la calidad su forma de vida “Bendita sea la crisis”, dice Antonio Zárate, director general de METALSA, al recordar 1982, año en que las ventas fueron las más de la década de los ochenta. Era el último año del sexenio de López Portillo y la economía había caído en un bache que no podía imaginarse tan sólo un año antes. “Las ventas se nos cayeron a la mitad”, señala Zárate. En esa época fue necesario cerrar las plantas durante...

reactions occur, changing the conditions makes them go faster. In metals it is common that some metals react more easily than others. The more quickly they react the more gas is given off. The substances in which the most reactive metals react are: Acids, Oxygen and Water. The most common reactive metals group is the Alkali. In the periodic table of elements, we can see there are metals which are more reactive than others. Some metals are more reactive than others; they are put in an order of reactivity...

the mechanism involved in HM adaptation. Introduction Heavy metals have been defined as the group of elements that have densities higher than 5 g cm23, and 53 chemical elements fall in this category. However, according physical, chemical or toxic properties, several definitions have been proposed to describe a heavy metal. Interestingly, the concept can include elements lighter than carbon, but excludes some of the heaviest metals. In an ecological scenario, a heavy metal could be considered...

However, this goal is difficult to achieve, economically, because of the complicated chemical and...

Corrosion attacks all engineering materials, especially metals. Corrosion is any chemical action which harms the properties of a material. It reduces the life material and increases the cost of a structure. For example, a steel bridge must be repainted regularly to protect it from rust. Various metals have therefore been developed to resist corrosion. Among them are the stainless steels. These metals contain from 12 to 35 % chromium which forms a very thin layer or film of chromium oxide on the surface...

surfaces. The two main reasons for colored pool water are oxidized metals and algae. A turbid green pool water condition is usually attributed to algae. To gain a better understanding of algae treatment see the section on algae.

Green, red, brown, and black are some of the more common colors produced by dissolved metals. Green color is usually produced by either copper or iron....

RESISTENCIA A LA TRACCIÓN Fully Cold Worked versus Fully Annealed Metals. The above discussion has considered ideal plastic metals, which, by definition, do not work harden during deformation and show a constant yield stress when the linear strain is increased as in a tensile or compressive test. Metals that have been sufficiently cold worked would behave in approximately this manner. However, fully annealed, and, in reality, most metals will have a tendency to work harden during deformation and will...

METAL A metal (from Greek "μέταλλον" – métallon, "mine, quarry, and metal") is an element, compound, or alloy that is a good conductor of both electricity and heat. Metals are usually malleable and shiny, that is they reflect most of incident light. In a metal, atoms readily lose electrons to form positive ions (cations). Metals are often extracted from the Earth by means of mining, resulting in ores that are relatively rich sources of the requisite elements. Ore is located by prospecting techniques...
