1.9 An alloy of 120g of lead (Pb) and 80g of tin (Sn) is melted and cast. At 100 C, two phases are found. There is 126.3g of the lead-rich phase and 73.7g of the tin-rich phase. It is known that the lead-rich phase contains W Pb =95% of lead. The constitution of
LEAD A. Commodity Summary Lead ore is mined domestically in several states. Seven lead mines in Missouri, along with mines in Alaska, Colorado, Idaho, and Montana yield most of the total ore production. (BOM, 1995, p. 94) In 1990, primary lead was
A 50 wt% Pb-50 wt% Mg alloy is slowly cooled from 700 C (1290 F) to 400 C (750 F). Use Magnesium-Lead Phase Diagram from Question 2. (a) At what temperature does the first solid phase form? (b) What is the composition of this solid phase? (c) At
Lead is extracted from its ore by reduction with carbon. Considerable effort has to be made to separate the lead ore from zinc ores. In recent years, lead has become one of most highly recycled materials in general use. Uses of lead Over 80% of all lead produced
An alloy is heated to a certain temperature (always below its melting point) and then cooled in different ways and at different rates to achieve various degrees of hardness and strength. When high-carbon steel is heated above 760° C (1,400° F) and then cooled suddenly, for example, it becomes hard and brittle.

I n the aerospace industry, themost common aluminum al-loys used are 7XXX wrought products. The thickness of parts used range from 0.6 mm to 250 mm. Aluminum alloy 7075, 7050 extrusions are used exten-sively for stringers, and other struc-tural components.
According to the Li‐Mg phase diagram, magnesium and lithium phases (α‐Mg, β‐Li) coexist in a Mg 0.5 Li 0.5 alloy. Because each grain exhibited the same contrast in SEM and the same O content in EDS mapping, we conclude that each grain exhibits the same Mg and Li fractions and that β‐Li phase is primarily present in the grain boundary region between α‐Mg grains (Figure 1 b,c).
