摘要： The invention concerns a method of improving the dynamic properties of compacted and sintered products having a density between 6.8 and 7.6 g/cm3, preferably between 7.0 and 7.4 g/cm3. According to this method an iron based powder, graphite and a solid particular lubricant having a vaporizing temperature less the sintering temperature, preferably less than about 800° C. is compacted and sintered and the maximum particle size of the lubricant is selected so that the largest pores of a compacted and sintered product prepared from the composition are equal to or less than the largest pores obtained in a compacted and sintered product prepared from the composition without lubricant. The invention also concerns composition of an iron based powder, graphite and a solid particular lubricant having a vaporizing temperature less the sintering temperature, preferably less than about 800° C. and a maximum particle size less than about 0.3 of the maximum size of the iron based powder as measured by laser diffraction measurement.

摘要： An iron-chromium based brazing filler metal is provided which exhibits an excellent wetting behavior on a stainless steel base material. The brazing filler metal produces a brazed joint which exhibits high strength and good corrosion resistance. The brazing filler metal is suitable for brazing stainless steel and other materials where corrosion resistance and high strength is required. Typical examples of applications are heat exchangers and catalytic converters. The iron-chromium based brazing filler metal powder according to the invention comprises: between 11 and 35 wt % chromium, between 0 and 30 wt % nickel, between 2 and 20 wt % copper, between 2 and 6 wt % silicon, between 4 and 8 wt % phosporous, between 0-10 wt % manganese, and at least 20 wt % iron.
