STUDY ON THE CHROME INFLUENCE ON THE MECHANICAL PROPERTIES AND MICROSTRUCTURE OF THE TUNGSTEN BASED ALLOYS
Journal Title: ACTA TECHNICA NAPOCENSIS, Series: Applied Mathematics, Mechanics, and Engineering - Year 2016, Vol 59, Issue 0
Abstract
In this paper we have presented the studies and the researches done by the authors on the chrome addition effect on the mechanical properties and microstructure of the heavy alloys from the W-Ni-Fe system. The experimental results have shown that the chrome addition up to 3 wt. % in the W-Ni-Fe system, have influenced the density, elongation and the yield limit of the sintered samples. These results could be explained by the segregation observed on the interphase boundaries between the W based matrix and the chromium compounds with the Ni, Fe and O elements. Also, an interphase corrosion is produced from where is explained the lowering of the mechanical properties analyzed.
