- TITLE: INFLUENCE OF SINTERING TEMPERATURE ON THE STRENGTH PROPERTIES OF THE POWDER STRUCTURAL MATERIAL FROM THE SYSTEM FE-C-P
- ABSTRACT: In the present study the influence of phosphorus over the strength characteristics of the powder construction materials of triple system Fe-С-Р is detected. Research samples are subjected to a base iron powder type - ASC 100.29. To the iron matrix 0,2÷1,0%C and 0,3÷0,45%Р is added. Pressing is carried out with the effort of 600MPa and sintering is conducted at 950÷1250ºС for 30 min at a protective environment of dissociated ammonia. The density of the samples after sintering is in the range 7,10÷7,12g/cm 3. In tables and graphics are presented experimental results for tensile strength, yield strength and elongation.
