抄録

On the basis of the experimental results obtained so far by the authors, investigations have been made in an attempt to develop alloys of good properties with a relatively small content of beryllium.<BR>In each of the alloys with 1 to 1.5% beryllium and 1% or less cadmium, tin, antimony or zinc, the initial hardening rate and attainable hardness are increased, the mechanical properties are improved and the activation energy of precipitation is lowered on aging by addition of 0.3 or 0.5% of indium. In the case of alloy containing around 0.3%CeLa, the addition of indium exerts a bad influence on the age-hardening property, reducing the attainable hardness greatly. It may be considered that stable intermetallic compounds between CeLa and indium are formed, and thus most of these elements are stabilized in such a state that has almost nothing to do with the precipitation process. A study of a series of Cu-Be-Zn alloys containing up to 30%Zn, with or without indium addition, has also been made. The addition of about 0.5% indium makes them less sensitive to over-aging, and improves mainly their Kb (Spring limit Kb means maximum surface stress of the thine plate specimen, by which 0.1 mm permanent strain occurs on the gange mark, and is calculated by the equation Kb=1.5ftE⁄l2. (f: bending strain at the loaded point in mm, t: thickness in mm, l: the distance between the fixed point and the loaded point, and is selected by l2=4000 t.)) values in general.
