Abstract
A brass material and a process for the preparation thereof, which comprises an alloy of 61 to 65% by weight of copper with the remainder being zinc; the material evidencing a structure in which the recrystallized phases .alpha. and .beta..sub.1 are present in a discrete fine mixture having grain sizes of less than 5 .mu.m. The component of the .beta..sub.1 phase comprises at least 10% of the structure and is arranged in the form of discrete particles in the grain boundaries of the .alpha. phase.
Claims5
In a brass material, the improvement in that said material comprises an alloy of 61 to 65% by weight of copper with the remainder being zinc;
- said material evidencing a structure in which the recrystallized phases .alpha. and .beta..sub.1 are present as a discrete fine mixture having grain sizes of less than 5 .mu.m, the component of the .beta..sub.1 phase comprising at least 10%, of the structure and all of said phase being arranged in the form of a superfine distribution of discrete particles in the grain boundaries of the .alpha. phase.
