The Hardening Power Apparently Lags In the cooling- curves of the five series of steel which we have just discussed, running from the softest basic
This paper may be regarded as a report of progress of an investigation into the influence of prior exposure to different high temperatures, under different
Loss of Hardening-Power at and near V.—We know that steel is hardened by quenching from a certain red-heat or from any higher temperature; but that
Retardations If high-carbon tool-steel be heated to very dull redness and then suddenly cooled, for instance by quenching in water, it is not thereby considerably
In working brown iron-ore mines on the system employed at Longdale, namely, stoping from the top down, the usual procedure is to drive a succession
Every constructing engineer and designer knows how often it is desirable to provide a speed-adjustment between parts of a machine performing different functions, or between
To have a complete text for a Method for the Determination of Phosphorus we must first discuss the interaction with other elements: The Effect of
