light alloys, metals


Although the determination of the strength of metals and alloys at ordinary temperatures is an everyday matter, very little work has been done to determine their strength and elasticity at very low temperatures. Mallock and Schaefer have investigated certain metals at the temperature of liquid air, and have deduced formulae to express the relation between elasticity and temperature, while Andrade has given an expression for the flow of metals under large constant stress. This work was intended in part to find out if their formulae would apply to the very light alloys used here. Another object was to find, if possible, a still lighter alloy than any on the market, which would be strong enough to be used a s an engineering material, and not be atacked too strongly by water and weak acids.
