<p>Measurements of the thermal expansion of alpha and of beta brass in compositions such as Muntz metal, naval brass, etc., which normally are in equilibrium are given. Fundamental variations in behaviour as regards thermal expansion at temperatures up to 600 degrees C. were noted, due to the transformation in the beta constituent. Manufacturers of brass never quench 60:40 brasses, and data are given which show the ill effects of quenching. It is found that naval brass and manganese bronze which are quenched in such a manner as to leave the beta grains s
