Sintered materials testing in law temperature

Abstract

Alloying elements have an important affect upon the mechanical properties of the Sintered Materials. Latest research in the field of powder metallurgy show concern over attempts fatigue. Have been made to predict the endurance limit to fatigue for predicting the effect of residual porosity and the tensile strength. It was found that the surface finish of the samples has a great influence on the fatigue strength. The sample containing pores - those caused by transient liquid phase by the Mo particle - the adverse effect of such flaws on the fatigue strength, which was also found by testing the fatigue. strength. The test of compression at low temperatures is made between (100-120) K and are respected the conditions foreseen by the technical norms of execution of the performed trials at low temperatures. The test at compression at low temperatures consists, as in the case of the environment, in applying the compression charge until the apparition of the first fissure
