tungsten heavy alloy iron-nickel-mecaniscas very high characteristics and method for making such alloys.

摘要

MEANS ALLOY TUNGSTEN HEAVY ALLOYS - NICKEL - IRON VERY HIGH MECHANICAL CHARACTERISTICS AS WELL AS A METHOD FOR PRODUCING SUCH ALLOYS. These alloys are characterized that phase TUNGSTEN ALFA is shaped like butterfly wings dimensions of between 0.01 and 1 micron and phase GAMMA binder has a free JOURNEY MIDDLE less than 15 microns. The procedure involves SUFFER THE PRODUCT TO sinter and RECOCIDP AT LEAST THREE CYCLES operations consisting FOR EACH OF THEM IN TO FOLLOW THE CORROSION OF HEAT TREATMENT. THE invention applies in obtaining ALLOYS WITH A Rupture Resistance between 1300 and 2000 HPA AND PARTICULARLY INTENDED FOR USES OF VERY HIGH APPLICATIONS.
