Abstract

This paper presents the influence of heat treatment modes on product quality parameters. The experiments were carried out on Cu-DHP pipes at various annealing temperature and time. Grain size and mechanical properties dependence on annealing mode were plotted for phosphorus-containing copper. Laboratory results were taken into account for setting process parameters and were industrially tested.
